How to Use this Handbook
Among the Liberal Arts and Sciences courses, the Basic Courses in Natural
Sciences: "Laboratory in Physics," "Laboratory in Chemistry," "Laboratory in
Biology," and "Laboratory in Earth Science" are all practical-style classes focusing
on experiments and observations.
Therefore, students are expected to operate equipment and instruments, handlechemicals and biological and mineral samples by themselves, and actively
participate in the classes through field observations. Such classes allow students
to acquire a great deal of academic knowledge which is not possible in a lecturestyle class but also provides a valuable opportunity to interact with faculty members
and Teaching Assistants (TAs) through one-on-one instruction. On the other hand,
students must always be aware that there are significant risks associated with theclass, such as accidents. Of course, these classes are designed for students who
have just started the first year of university. As long as students conduct theexperiments following the safety precautions, students will be able to enjoy theclasses without any worries.
This handbook is roughly composed of two major sections: Common Safety
Precautions in all laboratories and Specific Safety Precautions in each laboratory.
First, carefully read and understand the common precautions written on pages 1
and after. In this section, basic safety information such as the procedure of firstaid and extinguishing a fire, as well as important information on what to do in an
accident. Next, carefully read the relevant pages of the class you will attend. Thesepages contain precautions and instructions on how to handle equipment and otheritems to ensure safety tasks in each class. Be sure to read and understand thecontents of this handbook before starting experiments, and conduct experimentswith an awareness of safety. Of course, just by reading this handbook carefully
safety of the experiment is not 100% guaranteed. Each student is required tounderstand the contents of the class well. To better understand the content of theclass, reading and understanding the textbook and handouts used in class will bealso important. Safety precautions may be included in the textbook, and given
verbally or on a whiteboard during class. Please follow them carefully.
Because the contents of this handbook will serve as a basis for the safety
education necessary for future advanced experiments and practical training inspecialized courses and graduation research. We hope you will use this handbook
effectively, enjoy the class safely and spend fulfilled university life.

Common Precautions

1. General Precautions for Laboratory Experiments
No Eating or Drinking
Eating and drinking are strictly prohibited in the laboratory.
Organizing the Experimental Table
Keep the laboratory desk tidy and clean, and only put necessary items for an
experiment such as the laboratory equipment, a textbook, a laboratory notebook,writing materials, and calculators.

Where to Place Personal Belongings
Bags, coats, umbrellas, and other personal belongings should be placed on
shelves or other designated places. When a locker is available, personal
belongings should be stored in it. Do not place luggage on the floor in the lab,as it may obstruct traffic or evacuation, and cause accidents.
Explanations at the Beginning of the Experiments
At the beginning of experiments, the instructor will explain the contents of theexperiment as well as the things to be considered as a risk assessment. You
should understand the explanations before you start the experiment. Some
precautions might be explained during the experiment.
Description of Precautions
Precautions are also described in the textbook. These precautions should bestrictly observed when conducting experiments.

12. Waste from Laboratories
As overall, Nagoya University is committed to waste reduction and recycling. Waste
at the university is classified as (A) general waste and (B) experimental waste.
Each type of waste must be treated and disposed of appropriately. The waste
generated by experiments is classified as experimental waste, and it is strictly
prohibited to bring other waste and unnecessary items into the laboratory due tothe limited number of waste containers in the laboratory. Each of those types ofwaste is prescribed in the Nagoya University General Waste Collection andTreatment Guidelines and the Nagoya University Waste, etc. Treatment Methods.
You need to understand and follow these guidelines and methods for handling ofwaste, which is one of the basics for future experimental practice at Nagoya
University.
Waste Classification（A）General waste: Waste which is generated from activities such as studies,etc.
(Including paper, plastics, and other materials which are not used inexperiments. Naturally, this means items that are not contaminated by chemicals
or experimental samples).
（B）Experimental waste: Waste which is generated from experiments.
(Note that this includes regardless the chemical pollution.)

2

（A）Disposal of General Waste
Dispose of the waste separately according to the method prescribed in the Nagoya
University General Waste Collection and Treatment Guidelines. Be careful tosurely separate these containers from the experimental waste containers provided
in the laboratory. Only limited types of general waste containers are provided in
the laboratories. The other types of waste should be disposed of in the designatedcontainers on campus.

（B）Disposal of Experimental Waste
The presence or absence of pollution or contamination of chemicals etc. is not acriterion for classification as general waste or experimental waste. Whendisposing of damaged laboratory equipment, it should be treated as
experimental waste even if it is unused. For each type of chemical waste, waste
container, glass waste, metal waste, paper, plastic, etc., subdivide the waste
into the following categories according to the type of adherent (contained)chemicals and experimental samples used: those containing cyanide, heavy
metals (lead, copper, etc.), halogenated organic solvents, infectious biologicalsamples, etc., and dispose of them in the designated containers. The primaryand secondary washing solutions of instruments that have been handled withchemicals should also be treated as experimental waste. Dispose of these inaccordance with the Nagoya University Waste, etc., Treatment Methods.
Students should follow the experiment text, laboratory notices, etc., wash theequipment when necessary, and dispose of the waste in special containers in thelaboratory. Cleaning solutions for laboratory equipment should also be disposedof in the designated waste containers until the second time. Depending on thecontents of the experiments, the necessary waste containers are provided in thelaboratory. The containers should not be filled above 80% of their capacity. If
you need to change the container, ask an instructor.

43. Handling of Electrical Equipment and Devices
Handling of Electrical Equipment and Devices in the Laboratory

Grounding of Electrical Equipment
Since the low-voltage sides of the power distribution equipment and electricaldevices used in the experiment are not all grounded (earthed), you must be
careful to avoid electric shock. Avoid wiring using an overloaded power strip, andthe rated current value of the connected electrical equipment (or the total
current value if there are multiple devices) should not exceed the allowablecurrent value of the table-top, etc.
Electrical Hazards and Fires Caused by Electrical Leak
When we handle some electrical equipment, we should pay particular attention
to avoid electrical shock and fire caused by electrical leak. The details of thisare mentioned later.

Responding to the Failure of Electrical Equipment
Power Disconnection
If the power supply disconnects due to a tripped breaker or a fuse blowing, do
not try to repair or restore the power supply by yourself. The power should beturned on again after receiving inspection as it were and permission from theperson in charge.
Malfunction of Equipment
If any electrical equipment is not working properly, notify the person in chargeof the experimental theme before turning off the power switch. After the person
in charge has inspected the cause of the malfunction and repaired theequipment, and after receiving permission, use the equipment again.

Preventing Electrical Hazards
Basic Knowledge of Electric ShockElectrical shock hazard can lead to serious, even life-threatening, accidents, so
the greatest care must be taken when handling electrical equipment inexperiments. It could be considered the degree of damage caused by an electric
shock is determined by the magnitude of the current flowing through the humanorgans . The effects on the human body of electric shock from 60 Hz alternating
current are classified into the following stages.
１mA
No pain, just feel
５mA
Considerable pain
10mA
Unbearable pain
20mA
Muscle contraction is so severe, unable to break free from thecircuit on own
50mA
It is quite dangerous
100mA
Fatal consequences
The resistance in the human body is low, estimated to be about 500Ω at most.
If there were no skin contact resistance, the current flowing through the humanbody would be as much as 200 mA in the event of a 100 V electric shock, which
would be fatal. Therefore, the effect of electric shock on the human bodydepends on the resistance between the high-voltage side and the skin incontact, and the resistance between the human body and the ground potential.
To prevent electrical shock hazard, it is important not only to take care not totouch exposed metal parts that are energized, but also to conduct experiments
by eliminating causes of low resistance in contact areas and current paths, suchas wet hands or skin, wet floor, or body parts touching the ground wire.

Precautions to Prevent Electrical Hazards
Water Spillage and Electric Shock

Do not handle electrical equipment with wet hands, feet, or at the time yourfeet are wet or the floor is wet.
When using water or ice in some experimental themes, special care must be
taken.

Sufficient Understanding of Wiring

Fully understand the electric devices and wiring used to ensure that you cantake the proper actions promptly in the event of an accident.

Exposed Metal Parts

Be careful not to touch exposed metal parts of electrical circuits such as power
supplies, wiring, and terminals.

Operation of Electrical Equipment


Do not operate electrical equipment with tools, writing utensils, etc. in yourhands.

Disconnection of Power Supply at the Time of Wiring

Always turn off the power switch and unplug from the power supply box or walloutlet before wiring, rewiring, or un-wiring an electrical circuit.

Capacitor Discharge

7Since capacitors may be used in the electrical circuits inside electricalequipment, allow a little after switching off to discharge the capacitors whenchanging or disconnecting the wiring.

Precaution Against Electrical Fires and Burns Accidents
Electrical Fires and Burns Accident in Laboratories
Electrical leakage and poor connection in electrical circuits possibly
become the causes of electrical fires and burns. The following points
should be noted to prevent such accidents.


Except in cases of special instructions, such as computer-related equipmentthat is not switched off, unplug it from the power supply box or wall socket
after the experiment and do not leave it plugged in.
Tighten the screws at the terminal connections of electrical circuits
sufficiently so as not to cause a poor connection. Particularly, sufficient careshould be required with experimental equipment that will be energized for along period of time.
Pay attention not to burn yourself by touching high-heat parts.

How to Deal with in Case of Getting a Burn
In case of getting a burn, firstly cool the burn by running tap water. It would
be better if slightly above the burn, not directly, could be poured running water.
If the burn has gotten with clothes on, cool the burn over clothes with runningwater. Use the tap water from the sinks provided in each laboratory. At the sametime, ask someone nearby to contact the faculty members and receive
instructions.

Fire Extinguisher
１) Fire extinguishers are located in the corridors of each building and in thelaboratories.
２) Check the installation locations and learn how to use them so that they canbe used immediately in the event of a fire.
(1) Remove the safety pin.
(2) Disconnect the hose with the dominant hand and point it toward the fire.
(3) Squeeze the lever tightly.
(4) Extinguish the fire from the periphery of the burning part toward thecenter.

Source: the website of Nagoya University Environment, Health & Safety Office３) There are two types of fire extinguishers in the laboratory: powder
extinguishers and carbon dioxide extinguishers. Carbon dioxide
extinguishers are partially painted green. Either type of extinguisher can beused for most fires, but if metallic sodium or metallic magnesium starts toburn in a chemistry laboratory, a powder extinguisher must be used. When
extinguishing fires nearprecision equipment suchas computers, the use of acarbondioxideextinguisher is desirable
to prevent damage to theequipment. When using acarbondioxideextinguisher to extinguisha fire in a wooden productsuch as a laboratory tableor furniture, be aware thatthe fire may reignite after
a while even if the fire iscarbon dioxide fire extinguisher

6. How to Prevent Disasters Caused by Experiments -Actual
Examples of Disasters in Experiments
Experiments in Laboratory in physics, chemistry, biology, and earth sciences will be
the first experiments that students experience at the university. Therefore, extreme
care is taken with regard to the content of each experiment and the experimental
equipment and chemicals used to prevent accidents from occurring, and even if an
accident does occur, to minimize the risk of injury as possible is also paid attention.
However, no matter what measures are taken to prevent accidents, there are no"absolutes," and a certain number of accidents have occurred in experimental
classes of Liberal Arts and Sciences. In order to prevent such accidents, it isimportant to know what kind of accidents and disasters actually occur, so that ithelps to be able to minimize them.

Disasters Due to the Experiments at Nagoya University
The statistics and examples of recent experimental accidents at Nagoya University
are described below, so they could be a reference for preventing accidents inexperiments.
Laboratory Accidents at Nagoya University

Since these accidents mainly occurred in chemical and biological experiments,
special attention should be paid to them. The following is a list of specificexamples of accidents, their causes, and countermeasures.

15

Accidents Involving Glass
１) When a person tried to pass a glass tube through a hole in a rubber tube ora rubber stopper, the glass tube was broken, causing lacerations on the handbecause the hand holding the glass tube and the hand holding the rubber
capillary or the rubber stopper were far apart.
２) A person shook a mixture of ether and water in a separation funnel hard,which caused the glass to break under pressure, resulting in a cut on the
thumb of the right hand. After first aid treatment at the Health Service
Center, a person received three stitches at the Nagoya Diani Red Cross
Hospital.
３) A person tried to grab a broken measuring flask that had been knocked overby catching in the hand, and a person cut the left middle finger in the shapeof a hook with the broken part. 3 stitches and going to the hospital fortreatment for about one week were needed.
４) When a person tried to open an old reagent (pyruvic acid) in an ampule witha hot bulb, the internal pressure increases due to heating, causing an injury
by bursting the ampule and sticking the glass into one’s hand.
５) When a person put one’s hand in the sink of the experimental table, a finger
was cut with a piece of glass that had fallen into the water.
Countermeasure
These accidents could have been avoided by understanding the strength ofglass, using common sense in handling such as not applying more force thannecessary, inspecting glassware used in experiments, wearing protective
gloves when handling glass, and organizing the laboratory table.

Accident Involving Electricity
１) As a screw at the end of the power cord came off, short-circuited withanother wire, and burned the coating, the switchboard was turned off andthe fire was extinguished. There was no human casualty.
２) While changing the wiring of the experimental circuit, an excessive current
flowed to the cord of a table tap on the table due to a wiring error, which
generated heat, melted the sheath, and caught fire. The switch was turned
off and the fire was extinguished with a fire extinguisher.
Countermeasure
These accidents could have been prevented by having sufficient knowledge ofthe experimental equipment and electrical circuits used in advance, and byinspecting the experimental equipment and circuit wiring to be used.

16

Others１) (Gas leak) The main gas valve was damaged, and there was a considerable
amount of gas leakage so that the smell of gas could be recognized even in
the corridor.
２) (Fire accident) While drying sand samples in a heat-resistant acrylic
container at 100°C in a dryer, a part of the dryer became locallyoverheated, causing the container to melt and fall on the heating line,
igniting a fire that was extinguished with a fire extinguisher.
３) A student got burned by knocking over a hot oil bath in an experiment.
Countermeasure
It is necessary to understand that high-temperature heat sources and firesources can cause burns and fires and to manage and handle them with care.
Accidents can be prevented by inspecting equipment, checking heat-resistanttemperatures, and taking measures such as cooling hot objects to a safe
temperature before handling them. In addition, in preparation for theoccurrence of a fire that can be extinguished with a fire extinguisher, it isnecessary to inform everyone about the location and use of fire extinguishers
on a daily basis.

17

Examples of University-wide Education Courses

CASE 1
During a chemistry experiment, a chemical (unknown type) unintentionally adhered
to a person’s arm. The person was treated at a hospital for blisters, which required
the person to attend a hospital for two days.

CASE 2
During a chemistry experiment, while attaching a safety pipette filler to a volumetricpipette, the volumetric pipette broke off and pierced the left hand, causing a cut.

CASE 3
During a chemistry experiment, when removing a rubber dropper from a glass
pipette, a lateral force was applied and the top of the pipette broke off, pierced his
right hand, and injured a cut.

CASE 4
During a chemical experiment, a chemical adhered to the hand. The person
unconsciously rubbed his or her right eye with his or her hand. The eye was rinsed
with water, but his or her eye became slightly swollen and he or she felt that thevision was limited. After visiting an ophthalmologist, the eye was cured later.

First-aid (Treatment)
How to Stop Bleeding
Normal bleeding will stop naturally if the wound is kept under pressure.
For massive bleeding, call an ambulance.
Avoid direct contact with the wounded person's blood to prevent infection.
A plastic bag can be used as a glove.
Direct Pressure Method to Stop Bleeding
Press a cloth directly to the wound. Use a clean, thickly
folded cloth.
Choose a cloth that can sufficiently cover the wound.
Burn１) In case of relatively minor burns① Immediately cool with running water for at least 15 minutes, then apply
clean gauze.
② Do not apply any medicine, and be careful not to break the blisters.
③ If the burn is covered with clothing, cool it with running water over theclothing. If the clothing is sticking to the skin, do not forcibly remove it andseek medical attention.
２) In case of severe burns① In case of extensive burns, wrap the body with a clean sheet, etc. and takethe person to a hospital immediately.
② Burns may occur in the airway when hot air due to a fire or gas explosion isinhaled. If nose hairs burn, or if the inside of the nose or throat tingles, seek
medical attention.
Chemical Accident※※

If a chemical gets on the body, flush the body with tap water or shower forat least 20 minutes. Do not rub with a brush.
If a chemical gets into the eye, keep the eye crackling and moving up, down,
left, and right for at least 15 minutes in a washbowl with running cleanwater. If alkaline chemicals get into the eye, it is necessary to wash
thoroughly, so wash the eye for about 30 minutes. After that, see anophthalmologist.
※ Also refer to the "Laboratory in Chemistry " section of this manual.

22

Fractures, Dislocations, Sprains
１) A fracture is suspected when there is severe pain or deformity at the injured
area. In this case, fix the injured part with a splint so as not to pressure on
it, and go to a hospital for examination.
２) Dislocations should also be fixed with a splint or triangular bandage andpromptly taken to an orthopedic surgeon.
３) When a strong force is applied to a joint, a sprain occurs the surrounding
tissues (ligaments) are torn or make hyperextension, causing pain andswelling. The affected area should be cooled and kept at rest. If the swellingand pain are severe, see an orthopedic surgeon.
４) In case of Achilles tendon ruptures, should fix the part with a splint, and takea person to a hospital.

23

8. In the Event of a Major Earthquake, etc.
Emergency Exits for the Laboratory
The recognition of emergency exits should be always
required.

When instructed to evacuate, follow theguidance of instructors and TAs and evacuate thebuilding in good order without panicking. Follow theevacuation signs (arrows) in the corridors. Leave yourbelongings in the laboratory when evacuating. Avoid a
private conversation. If someone is injured, help him or
her out of the building.
Earthquake Early-warning Issued
When an earthquake early-warning is issued, stop the experiment immediately
and return the chemicals and equipment in use to the designated chemical cabinet(where they were originally placed) without panic. Turn off the water supply andunplug the electrical outlets. After that, follow the instructions of the instructor
and evacuate calmly.

If an Earthquake Occurs During the Experiment
If you feel a strong earthquake, do not panic and go outside the laboratory. If it
is not possible to go outside the room, move as far away as possible from thecabinets for chemicals and equipment, and wait in a safe place where objects will
not fall until the shaking stop. Since chemicals and other harmful materials might

Laboratory in Physics

Aims and Safety Precautions for Physics Experiments
Laboratory in Physics is one of the physics subjects for first-year science students.
Particular emphasis is placed on "hands-on" experience of various experiments byconducting experiments on one's own.
None of the experimental topics in the class are particularly hazardous, as long as
the experiments are conducted carefully. However, as with experiments on any
subject, it is not always safe to do anything without prior knowledge. Eachexperiment has the possibility of accidents, even if the probability is very small. It
is extremely important to understand the content of the experiment well, toanticipate possible dangers, and to conduct the experiment with a moderate senseof urgency in order to prevent accidents.
The following is a list of accidents and disasters that can be expected when
conducting physics experiments, as well as precautions to prevent them. Please
read the contents carefully, understand them, observe the precautions, and try to
prevent accidents from occurring. In the event of an accident, contact an instructor
immediately for instructions.

1. Introduction
Before Starting the Experiment
Clothes for Experiments
No specific lab coats are specified for physics experiments. Each student musttake care to dress appropriately for the experiment and be careful not to cause
accidents. For example, avoid excessively revealing clothing even in summer, andremove overcoats and thermal jackets in winter. In addition, metal jewelry should
be removed to prevent electric shock.
Preliminary Study for the Experiment
Students should have a good understanding of the contents of the experiment,
the experimental equipment used, and the possibility of accidents occurring,using the experimental text and video materials so that you will be able torespond quickly and appropriately in the event of an accident.

Video materials http://elearn.ilas.nagoya-u.ac.jp/lms/pex_e/

Preparation Before Starting the Experiment
Before starting the experiment, it is most important to read the experimental
guidelines carefully, compare them with the experimental apparatus, andfamiliarize yourself with the experiment and its operation in order to prevent
accidents during experiments. However, do not wire the experimental apparatus,
turn on the power, or operate the equipment until the instructor or TA in charge
has explained them.

27Precautions during an Experiment
Arrangement of Experimental Equipment
When conducting experiments, the experimental desk should be organized, theexperimental equipment arranged, and the electrical circuits wired, which are to
make it as easy as possible to operate the experiment. This is also necessary toensure the safety of the experiment.
Co-experimenter
Experiments are usually conducted by two persons. You must experiment withattention not only to yourself but also to your co-experimenter.

Other Experimenters
Only the person experimenting knows how the experiment is progressing in aparticular experimental set. Therefore, carelessly approaching otherexperimental desks or talking to the experimenter in the middle of an experiment
may cause accidents.

28

Precautions at the End of the Experiment
Experiment Completion Procedure
After the measurements and observations are completed, the experiment shouldbe terminated according to the indicated procedure.
The procedure varies with each experimental topic. For example, some power
supplies may or may not be turned off, and some electrical equipment andcircuits may or may not be unwired.
Computer Termination
The computer must always be terminated according to the indicated procedure.
Must be careful if failure to exit according to the correct procedure or to turnoff the power can destroy the system.
Handling of Power Supply Boxes and Wall Outlets
Except for the equipment that is instructed not to be turned off, all power supply
boxes and wall outlets other than those used for the computer should be
unplugged at the end of the experiment. However, the power supply box should
not be switched off.
Disposal of Experimental Waste
Dispose of all used and unnecessary items and replaced defective parts
separately in designated garbage boxes, etc.
① Combustibles such as paper, cloth, etc.
② Incombustibles such as lead wires, wires, fuses, glass pieces, etc.
③ Aluminum foil
④ Batteries29

2. Handling of Electrical Facilities and Equipment
Electricity Distribution and Equipment
In physics laboratories, 100 V AC voltage is usually supplied from the wiring ductin the ceiling to the power supply box on each experimental desk. In someexperiments, the power is supplied to the power boxes from wall outlets.
Students must not touch the electricity distribution equipment upstream fromthe power supply boxes and wall outlets.
High Voltage for Electrical Equipment
Some of the electrical equipment used in the experiment generates high voltages
inside. In these devices, be careful never to touch the high-voltage parts. Even
if the high-voltage parts are not exposed, be careful not to leak current into theequipment.

3. Handling of Radioactive Materials and Radiation
Radiation Sources Used in Experiments
Radiation Source to be Used
In the experimental theme "Measurement of radiation, "theradioactive isotopes strontium-90 (90Sr, a half-life of 28.8
years) and yttrium-90, 90Y, a half-life of 64.1 hours) are usedas radiation sources. They are sealed source and radioactive
materials in an aluminum dish container are capped on the top
by an aluminum thin film of approximately 0.015 mm (15 μm).
Radioactivity Intensity of the Radiation Sources
The radioactivity intensity of the radiation sources is approximately 1.5 kBq (0.04μCi) and approximately 3.7 kBq (0.1 μCi), respectively. Beta rays (electrons) of
the maximum energy of 0.546 MeV are emitted from 90Sr and beta rays of the
maximum energy of 2.28 MeV are emitted from 90Y.
Along with the beta rays, gamma rays of 1.76 MeV at the intensity of 0.01% arealso emitted from 90Y. In addition, X-rays are generated as secondary radiation
as a result of bremsstrahlung when beta rays collide with aluminum, etc.

31

Handling of Radiation Sources in Experiments
Prevention of Radiation Exposure and Contamination
Care must be needed to minimize radiation exposure to the human body as muchas possible and to ensure that contamination by radioactive materials neveroccurs.
Handling of Sealed Radiation Sources
As sealed radiation sources are used in the experiments, no contamination would
occur unless the seal is broken to leak the radioactive materials externally.
Nevertheless, since the aluminum film used for the seal is as thin as
approximately 15 μm, radiation sources must be handled with the greatest
possible care not to break the aluminum film. Do not touch the film on the
top of the source container, poke it with tweezers or writing utensils,
drop the source or otherwise impact it.
Abnormality Notification and Instructions
If you suspect that the aluminum coating has been damaged or contaminated byradioactive materials, contact an instructor, or other staffs immediately andreceive instructions.
Do not take measures on your own.
Minimizing Radiation Exposure
Since the radioactivity of the radiation sources used in the experiments is weak
and most of the radiation emitted is beta rays, and gamma rays and secondary
X-rays are at the level of natural counts, no special shielding is required.
However, care should be taken not to keep the radiation sources in close contact
with the body for long periods.
Minimization of the Time of Use
Take care that the radiation source is used only for short periods. Do not leave
the radiation source unattended on the experimental table. After bringing out
a radiation source, immediately attach it to the measurement table and return itto the designated place immediately after the measurement is completed.

32

Stronger Radioactivity
While in the handling of radiation sources of the level of radiation intensity usedin this experiment, no precautions other than those mentioned above arenecessary, the followings are precautions for handling stronger radioactivity.
① To minimize radiation exposure, the following points should be considered.
Place a shield between the radiation source and the human body
Keep the long distance between the radiation source and the human body
Reduce the time of exposure to radiation
These are called the three principles of radiation protection.
② The blood-forming tissues, gonads, and lens of the eye are the organs of the
body most vulnerable to the effects of radiation. Do not put your eyes close
to the radiation source to look into.

33

4. Handling of Cryogens (Dry Ice and Liquid Nitrogen)
Chemical Agents Used in the Experiment
Cryogens Used in Experiments
Cryogens are materials used to achieve low temperatures necessary forexperiments.
Their temperatures are low and their form while in use may be different from thatat room temperature. Accordingly, the physical and chemical properties of thematerials must be fully understood and care must be needed to handle them. In
the experiment theme "Specific heat of solids" and "Physical property experiment using liquid nitrogen," a mixture of ice and water (at 0 ℃) and liquid
nitrogen (-196 ℃) are used. While precautions on an everyday level, such as
avoidance of long-time contact with skin to prevent frostbite, are sufficient forhandling the mixture of ice and water, the handling of liquid nitrogen and its
hazards are described on the following pages.

34

Handling of liquid nitrogen
Precautions in Handling it
Liquid nitrogen is a colorless, tasteless, odorless, low-temperature liquefied
gas, and its temperature under atmospheric pressure is -196℃, which is its
boiling point. The density of liquid nitrogen is 0.81 g/cm3, and when vaporized
it becomes 1.25 x 10-3 g/cm3, so 10 mL of liquid nitrogen will have a volume ofabout 6.5 L when vaporized. Therefore, attention is required because there arerisks of oxygen deprivation bursting the sealed container. To prevent oxygen
deprivation, ventilate the room sufficiently, and be sure to check the decreasein oxygen concentration with an oxygen analyzer. When pouring liquid nitrogen
into a container at room temperature (the act of pouring is performed by theteaching assistant (TA) or instructor in charge), the liquid nitrogen may vaporize
explosively and fly out, so hands and faces must be kept away. Be aware thattouching liquid nitrogen or cooling equipment with bare hands can cause severe
frostbite.
Handling of Liquid Nitrogen in the Experiment Subject of "Low-temperature
Properties of Materials"
Liquid nitrogen is stored in a Dewar, which is exclusively designed for its storage,in the laboratory. All liquid nitrogen containers are handled by only the TAs or
instructors in charge, so do not touch them. When liquid nitrogen is needed for
pouring into or replenishing each experimental container, please ask your TA or
instructor for transferring or refilling of the liquid nitrogen into the container
required for each experiment. Never add liquid nitrogen to the aforementioned
container yourself.

35

Prevention of Suffocation Accidents
Oxygen Deprivation due to Vaporization of Cryogens
When liquid nitrogen vaporizes and is released into the air in large quantities, itcauses the oxygen concentration to drop and suffocate. The oxygen
concentration in the air is 21%, but the "safe limit" is 18%, and below this levelis called "oxygen deprivation," in which oxygen deprivation symptoms appear.
When a person suffers severe oxygen deprivation, he or she is unable to leave
the room or open a window on own. If the oxygen level drops below 6%, it causes
death. In general, a person who collapses due to oxygen deprivation will not beable to recover until first aid is administered within 3 to 6 minutes after theaccident. The table below shows the approximate effects of a decrease in oxygen
concentration on the human body.

lower level
One of the reported cases of a fatal suffocation accident was a case in which alarge amount of liquid nitrogen was spilled out in a closed room. Because it isvery dangerous, leftover liquid nitrogen should not be used for any purpose otherthan experiments. Thoroughly ventilate the room while using the refrigerant, anduse an oxygen analyzer to check whether the oxygen concentration in the roomis decreasing.
Handling of Leftover Liquid Nitrogen
Any leftover liquid nitrogen during the experiment should be allowed toevaporate into the air naturally outdoors, and should never be poured into
containers such as plastic bottles. Because it can cause rupture, frostbite, orother accidents.

5. Handling of Lasers
The Hazards Level of Lasers and Lasers Used in Experiments
Classification of Lasers by Hazards Level
Laser light is a phase-aligned, highly directional light with a higher energy
density than light from ordinary light sources. Therefore, high-power lasers not
only direct light but also reflected and scattered light may cause blindness andburn. The table below classifies lasers according to their hazard level. For
example, a red laser pointer often used, is classified as Class 2. Even a Class 2
laser can cause eye damage if irradiated to the eyes for a long period, laser lightmust not be looked at directly. The higher the class has the higher output and ismore dangerous. When using lasers of Class 3 or higher, protective goggles must
be worn.

Overview of Hazard Assessment
Essentially safe or made safe by technical design. Almost nonhazardous under normal operating conditions. Maybe hazardous
when observed or disassembled in the beam by optical means suchas lenses.
The output of1 mW or less. Although not essentially safe, in thecase of this class of laser light, the eye will be usually protectedwith the eye's aversion reaction (blinking) even if it accidentallyenters into the eyes. Observation with a lens or other opticalmeans within the beam or prolonged exposure maybe dangerous.
In principle, the output of 5 mW or less. The observation in the
beam is potentially dangerous. If the beam is focused using a lensor other means and entered into the eyes, it may cause damage.
The output of 0.5 W or less. Direct or specular reflected lightshould never be observed in the beam, as it is always dangerous
and causes damage. Irradiation of the skin should also be avoided
as much as possible.
High-power lasers exceeding 0.5 W are dangerous not only interms of direct light and specular reflection but also in terms ofdiffuse reflection. It is dangerous not only to the eyes but also to
the skin and may cause fires.

Laser to be Used
In the experimental theme "Polarization", semiconductor lasers (wavelength:
635 nm, output power: 1 mW or less, equivalent to Class 2) are used.

37

Precautions for Handling Lasers
Attachment, Removal, and Adjustment of a Laser
To prevent direct or multiple reflected laser light from entering the eyes of theexperimenter or yourself, the laser is turned off and no light is emitted whenalways mount or dismount the laser on the optical bench. Adjust the opticalsystem as much as possible while the light is not emitted, and then turn on the
output after terminating it securely with a beam block, etc..
Eye Height and Eye Angle
Do not place your eye at the height of the optical path plane created by the
direct or reflected light of the laser. When checking the beam shape or adjusting
the optical system, shine the laser beam on white paper, etc. and observe thescattered light from a suitable distant position at some angle from the optical
path plane. Never look directly into the light or reflected light.
Jewelry and Accessories Worn, Especially Worn on the Hands
When adjusting optical systems with laser beams emitted, laser beams may hit
the glass surface of necklaces and wristwatches, or its belt parts, rings, andother wearing jewelry, and the reflected beams may fly in unexpected directions
and enter your own eyes or the eyes of other experimenters. Remove these items
from yourself when making an adjustment.

Eye Damage due to a Laser
Laser Wavelengths and Eye Damage
Laser beams with visible light (400 nm to 780 nm) and some infrared light (780
nm to 1,400 nm) are focused on the retina by the eye's optical system (cornea
and lens) and have an energy density that is approximately 100 times greater,
destroying the retina and causing visual impairment. Destroyed retinal cells do
not regenerate. Laser beams with ultraviolet light (200 nm to 400 nm) and someinfrared light (from 1,400 nm) are absorbed by the cornea, lens, and othertissues, causing corneal burns and cataracts with vision loss. Ultraviolet andinfrared light is more intense than they appear, so care must be needed.

38

6. Precautions in Handling Various Types of Experimental Equipment
Glass Equipment
Vacuum Glass Equipment
Some experimental themes use glass
vessels whose interior is in a near-vacuum
state such as measurement tubes for
specific charges of electrons. Note thatthese glass devices are constantly under 1
atmospheric pressure (i.e., approximately 1
kg of force per cm2) from the outside. In
such equipment, if a part of it breaks, theentire of it is destroyed at once, which isextremely dangerous. Therefore, care must
be needed to avoid shocks to vacuum glass
equipment and to prevent any sharp object
such as pens and rulers from touching it.

atmospheric pressure

Thermometers and Glass Containers
Ordinary glassware such as thermometers and glass containers can also cause
serious and unexpected injuries unless it is handled with care.

Laboratory in Chemistry

Aims of “Laboratory in Chemistry” and Safety Precautions
The aim of the course “Laboratory in Chemistry” is to enhance your interests anddeepen your understanding of chemistry by performing experiments and considering
the experimental results well. Since chemistry is a discipline that deals with theproperties and changes of substances, you will handle some substances handled in
the course that are highly reactive. These substances are often more dangerous
than ordinary ones around us.
For safe experiments, it is important to assess the occurrence and severity of therisks and, to take precautionary measures for preventing accidents and minimalizing
the risks. Experiments in “Laboratory in Chemistry” use small amounts of chemicals
and are relatively safe. Even so, there are always risks of accidents especially when
you handle chemicals in the wrong way. Therefore, you must pay maximum attention
during experiments. Since the biggest causes of accidents are lacking knowledge,
ignorance and carelessness, please read and understand the following safety
guidelines carefully before starting experiments.

40

1. Introduction
Proper Lab Clothing
Safety Goggles
Since the chemical exposure to eyes causes a severe
health problem, safety goggles are required to be wornin the chemical lab. Protection of normal eye-wear isinsufficient for lab use. Safety goggles should be wornover standard eye-wear. Contact lenses hold chemicals
and cause further damage. For this reason, eye-wear isstrongly recommended to be worn with safety goggles
rather than contact lenses.
Laboratory Clothing
A clean lab coat should be worn when performing
experiments. Wear a dedicated lab coat over clothes thatare comfortable to work in. Avoid wearing stockings or
exposing clothes (such as skirts or shorts) as they may
cause chemical injuries in case of spills of chemicals
adhesion.

Laboratory Gloves
Latex gloves should be used for experiments. If you areallergic to the material and find it difficult to wear the
gloves, please ask your instructor.
Shoes
Wear shoes that are comfortable and cover the entire
foot. Unstable shoes (high-heeled shoes and slippersetc.) are prohibited. Partly opened shoes (sandals andpumps etc.) are also prohibited. Slippery wet shoes
should be dried when entering the laboratory (shoematt).
Hair
Long hair can come into contact to chemicals or a hot
plate. Long hair is also a hazard around rotating
equipment. Long hair should be tied back with a hairband,
etc.

41

General Precautions in a Laboratory
Entering the Laboratory①

Wear a lab coat and protective goggles before entering the lab, and keepthem on until leaving the lab.
② Check emergency exits, evacuation routes, fire extinguishers, emergency
showers, and eye washers. Also, remove any obstacles on the aisle.
③ Check the instructions for the day (written on a whiteboard or given orally)
and make sure you understand them. If you have any questions, ask yourinstructor or teaching assistants (TAs).
④ Check apparatus and chemicals. Prepare in advance if something is missing.

Keep the laboratory clean and organized.
Do not leave any items on the floor or near emergency exits, fire
extinguishers, or emergency showers or keep standing near them, as it may
cause accidents or hinder evacuation. If water or chemicals are spilled on
the floor, wipe them up immediately.
Refrain from talking privately or walking around the room unnecessarily.
Handle chemicals with utmost cares. For handling of chemicals, refer to thesection "2. Handling of Chemicals and Poisonous Substances."
Waste (chemicals, glasses, papers, etc.) should be separated and disposedof in designated waste containers.
Follow the precautions for handling machines and instruments. For someequipment that requires special attention, refer to the section "3. Handlingof experimental equipment. "Always follow the instructions for experiments, such as "conduct in a fumehood". In principle, chemicals placed in a fume hood should be handled in thehood.

After the Experiment①②③

Wash hands thoroughly with a soap.
Wash used lab coats, towels, etc. promptly.
If you notice any accidents or something unusual, record them as muchdetailed as possible on your lab notebook and report them to your instructoror TAs.
④ It is forbidden to take out chemicals, instruments, equipment, etc. that are
installed in a laboratory.

42

2. Handling of Chemicals and Toxic Substances
In chemistry experiments, various hazardous chemicals may be used, such as
harmful substances (e.g., poisoning or injuring), flammables, allergens, carcinogens
and environmental pollutants. When conducting such experiments, utmost careneeds to be taken to protect your health. You should also bear in mind that organic
solvents such as alcohol and acetone are highly flammable and can catch fire easily
if they come close to a heat source or an electrical spark. Chemicals must also be
disposed properly according to the rules, otherwise they will have a serious impact
on the environment. Thus, to handle chemicals safely, we must know their properties
first and follow the rules. Before handling chemicals, read the contents of thissection carefully and understand the risks and proper handling of chemicals.

⑥

Do not take out a larger amount of chemicals than necessary for theexperiment.
Do not bring your face close to chemicals to smell or swallow them.
Point the opening of a test tube or a casserole away from you or any otherpersons during heating or stirring a solution, as the contents may spill.
Follow the text procedures unless you get permission for a modified
procedure from the instructor.
Close the lids of chemical bottles and pipettes to the original positions
immediately after use.
Organic solvents dissolve plastics and acid solutions corrode metals andelectronic devices. Such chemicals should be handled carefully as not to
expose them to skin or stationery and equipment.

Heating of Chemicals
Flammable organic solvents should be used away from hot plates because they
will ignite. Hot plates should always be cleaned from chemicals spills, even if not
flammable, as they may cause toxic gases by thermal decomposition.
Spilt Chemicals
When a flammable liquid is spilt, turn off the heat sources first. A small amountof liquid should be immediately wiped up with tissue paper or a dust cloth. Small
amounts of solids should be swept up with a small broom. The cloths used to wipe
off chemicals should be handled with laboratory gloves provided and be disposedof in designated boxes. Refer to “Waste from Laboratories” on p.2 in“Common issue” If you spill a large amount of chemical that cannot be wiped
up with a cloth, immediately ask for instructions from the instructor.

43

Disposal of Chemicals
Dispose of used chemicals in the following manner.
Disposal of Liquid Waste
At Nagoya University, liquid waste of experiments must be properly sorted,
collected, and disposed of. Liquid waste includes the solutions used in theexperiment and the first and second rinse of the apparatus and they should becollected and disposed of as follows.
When a plastic beaker for liquid waste is provided on a bench, collect the liquid
waste in it during the experiment and dispose of it in a plastic container (photo
below) after the experiment. After the disposal of a solution, glassware shouldbe rinsed with a small amount of deionized water twice, and properly dispose of
the rinsing solution is required. Plastic containers for liquid wastes are in eachlaboratory and are designated for a specific solution (organic, heavy metal,
cyanide, etc.). Liquid waste should be disposed of properly according to the
instructions announced in each lab. The maximum filling level of the container is
80 % of the capacity.

【Flowchart for Separation of Liquid Lab Waste】（On-campus only）
https://www.esmc.nagoyau.ac.jp/limit/eng/61_Laboratory_waste_treatment/Liquid_Waste_20200608.pdf

Disposal of Solid Chemicals
Small quantities of solid chemicals can be disposed of in a “Non-Infectious
Industrial Waste” box according to the instruction of instructors. If you need todispose of a large amount of solid chemical, ask the instructor for instructions.
Compounds obtained by synthesis should be wrapped in weighing paper andsubmitted to the designated plastic tray in the laboratory.

44

Risk Assessment of Hazardous Chemicals
To prevent accidents, it is necessary to evaluate the chemical hazards (riskassessment) and to understand the potential health or environmental effect of achemical. Information on chemical hazards can be easily obtained from the labels ofchemical containers or from documents issued by chemical producers. This section
introduces the SDS and GHS, which are often used to identify the chemical hazards.
Risk Assessment
Nagoya University requires that a risk assessment must be conducted for all
chemicals which you are going to use. A check sheet, which is available from the
URL link below, will help you to summarize the chemical hazards of each chemical
reagent and to confirm corresponding safety measures.
Chemical Risk Assessment Check Sheet
https://www.esmc.nagoyau.ac.jp/risk/Check_sheet_for_chemical_substance_risk_assessment.pdf
SDS (Safety Data Sheet)
An SDS is a document with information on the chemical hazards, which can beobtained from chemical producers. Information on chemicals used in theexperiments can be found by searching the internet with keywords like “Thename of the chemical, SDS”. An SDS includes information such as theproperties, hazards, protective measures, and precautions for handling ofchemicals in the following 16 sections. You are expected to understand inadvance the hazards and handling precautions of the chemicals that will be usedin the experiment.

GHS（Globally Harmonized System of Classification and Labelling of Chemicals）
GHS is a system of the classification and labeling of chemical hazards andtoxicity that is adopted by countries around the world. There are nine pictograms
under GHS that visually convey hazards. These pictograms are used not only forchemicals, but also for labels of daily items such as bleach. By knowing thepictograms and their meanings, they will provide clear warnings and thehazardous properties of chemicals.

Handling of Poisonous and Deleterious Substances“Poisonous and Deleterious Substances Control Act (in Japan)” was implemented
to control harmful substances from the viewpoint of health and hygiene. In order toprevent accidents and crimes associated with harmful substances, the law
stipulates the types of poisonous ( 毒 物 ) and deleterious ( 劇 物 ) substances,supplemental records of purchase, use and disposal, and secure storage in a lockedcabinet. The handling of poisonous and deleterious substances at Nagoya
University is regulated by the “Nagoya University Guidelines for the Managementof Poisonous and Deleterious Substances” and the “Poison Handling Guidelines
for Nagoya University Liberal Arts and Sciences Laboratory Work” (see links onp.65) “Poisonous and deleterious substances” can only be used under thesupervision of responsible instructors in the designated laboratories. Students whotake the Liberal Arts and Sciences laboratory courses are allowed to conduct
experiments handling the minimum necessary amount of poisonous and deleterious
substances under the guidance and supervision of authorized instructors and are
obliged to comply with the regulations and instructions.
Poisonous and Deleterious Substances Used in Class
The poisonous and deleterious substances used in the class are listed in the
textbook or will be introduced in the laboratory. Students are required to follow
the instructions for each chemical given in the textbook and explained by the
instructor. It is strictly prohibited to use more amount than necessary, to takechemicals out of the laboratory, or to allow outsiders to enter the laboratory(violation of regulations and laws). The laboratory is locked after the course.
When you find a loss of chemicals or any violations such as taking chemicals outof the room, let the instructor know immediately.

The Difference Between Poisonous and Deleterious Substances
Poisonous (毒物) and deleterious (劇物) substances in Japanese law are judged
on the basis of their poisoning potential to health from the knowledge listed
below. Poisonous and deleterious substances differ in their judgment criteria,
and the criteria of poisonous substances is designated as higher toxicity thandeleterious substances. In addition, since chemicals which are not designatedas poisons or deleterious substances by law may have similar toxicity, it isnecessary to be careful when handling any chemicals.
① Animal testing →a) Acute toxicity (LD50 values by oral, dermal, and inhalation)b) Corrosiveness to skin,c) Serious damage to mucous membranes such as eyes
② Human exposure → Toxicity examined and judged from accident cases, etc.
③ Others → Toxicity/irritation based on the knowledge of physicochemical
properties such as reactivity, in vitro tests, etc.

47

3. Handling of Experimental Equipment
Read the textbook and the instructions carefully to fully understand how to handle
the equipment and devices. The following is a list of cases of risks and accidents.
Heating
Unless otherwise specified, the chemicals are heated by a water bath ( a waterfilled beaker heated on a hot plate). The temperature of the hot plate surface ishigher than 600 °C when heated. Hot plate used in labs present potentials ofrisks such as burns and fires. Pay attention even after the heater is off because
it remains hot for a while, and it is hard to see the surface temperature.
Centrifuge
When you operate the centrifuge, test tubes in a rotor should always bebalanced. Put 2 (or 4) test tubes with roughly the same weight/amount ofsolution in them. Never open the lid of the centrifuge during operation.

High Voltage Power Supply
High voltages are applied to a hydrogen discharge lamps and sodium-vapor
lamps. Be careful not to touch the naked electrodes to avoid electric shock.

PipetteNever point the open end of a pipette toward yourself or others. When you takea solution in a pipette, pipette out it to a test tube or a beaker immediately. Do
not keep a solution in a pipette or move around the lab with a solution in apipette. A narrow pipette such as a hole pipette or a Pasteur pipette is fragileand should be handled with care.
Broken Glassware
To prevent and minimize the broken glass injury, broken glass should not be
handled with hands without protective equipment. When glassware is broken,
inform students around you not to approach and ask the instructor for cleaning.
Since small pieces glass are hard to find especially when they are wet, use
dustpan and brush for cleaning.

48

4. In Case of an Accident (Laboratory in Chemistry )Any accident in the lab should be reported to the instructor regard less its degreeof injury. Refer to the specific instructions shown below as well as in p.19”FirstAid and Life-saving Treatment”.
In Case of Skin Contact
In case of a small amount of an acid, alkali, or metal salt aqueous solution ororganic solvent such as acetone methanol, rinse the area thoroughly with water.
Other organic compounds should be immediately wiped off with tissue paper andcontact your instructor for the instructions. If a large amount of a chemical(especially corrosives) is on your body, remove the clothing on which thechemical has adhered and use an emergency shower to wash affected area (seep. 51).
If the chemical causes skin irritation during experiment, inform the instructor of
the type of chemical and receive treatment from a surgeon or dermatologist.
If you notice any skin irritation, blisters, or other abnormalities after returning
home, have medical examination immediately and report it to your instructor.

In Case of Eye Contact
Immediately rinse eyes thoroughly with plenty of tap water (see p. 50). Ask
students nearby or the instructor for help. Even if the symptoms are mild, be sure
to see an ophthalmologist.
If Swallowed
Immediately inform the instructor or ask students nearby to do so. Clarify thetype and amount of the chemical. Swallow of any chemicals other than diluteacids-alkalis (0.01M) requires medical treatment.
If Inhaled
If you feel nausea, headache, or dizziness after inhaling chemical vapors, go outof the room immediately and breathe fresh air. Ask someone around you to notify
the instructor and seek instructions.

If Injured
If any chemicals are on the wound, wash them off with a large amount of water
first. Depending on the size of the wound and the degree of bleeding, havemedical treatment at the infirmary or by a surgeon.

49

In Case of Skin Burn
Cool the burn under running water regardless of the degree of the burn. Ask
someone around you to notify the instructor.
In Case of Fire
Shout "Fire!" and move away from the fire. Clear away any combustibles near
the fire with students around you. The fire extinguishers are equipped in all labs
and on the corridor. As the scale of the experiment in the course is small, mostfires can be extinguished with fire extinguishers. Those who are not involved in
firefighting should take distance from the fire. However, if the flames reach theceiling, stop firefighting, evacuate the laboratory immediately followed byinstructions of the instructor, and activate the fire alarm.

If Clothes Catch FireA person nearby is responsible to notify the instructor immediately. Use
emergency shower to distinguish the fire. Never try to take off your clothes orroll on the floor to put out the fire.

50

5. Safety Equipment
Be sure to check the location of safety equipment in the laboratory and familiarize
yourself with its use.
Fume Hood (Local Ventilation System)
Fume hoods are installed in the room between the lab 1 and 2. The work area ofa fume hood is ventilated to use substances that may produce harmful gases orodors. Experiments which should be performed in it are given in the textbook.

Eye Wash Water Tap
Eye wash water taps are installed in the sink of each laboratory. When chemicals
contact the eyes, they should be rinsed with a large amount of water.

Emergency Shower
Emergency showers are installed on the wall of corridor. They can be operated
simply by pulling the lever. If your clothes catch fire or a large amount of achemical contacts your skin, use emergency shower.

Laboratory in Biology

The following describes common precautions to bear in mind when conducting
experiments. Be sure to understand the experimental procedures, etc., and follow
the basic rules of proceeding with the experiment with care to prevent accidents.
In Laboratory in Biology, a wide variety of living organisms and instruments arehandled. The individual precautions required for each lab theme will be explained in
the guidance before the start of the practical training. It is necessary for students
to attend the class without delay and fully understand the points to be noted.

52

1. Introduction
Personal Belongings
Since personal belongings will interfere with experimental operations, placethem in the designated area before class starts or in a locker for Liberal Arts
and Sciences students, and bring only the minimum necessary items to thelaboratory, such as pens, pencils, and lab notebooks.
Eating and Drinking in the Laboratory
Do not eat or drink in the laboratory. If you need to hydrate, keep a beverage inyour locker and go drink it if necessary.

White CoatWhite coats may be required due to the possibility of skin or clothing
contamination from various reagents, pigments, or animal blood. In such cases,
an announcement will be given in the guidance including how to obtain them, so
please follow it.

53

2. Handling of Chemicals
Although highly hazardous chemicals such as poisonous or deleterious
substances are rarely used in Laboratory in Biology, when using such chemicals,
listen carefully to the instructor's instructions and take extra care not to getthem on your skin or clothing. In addition, use the chemicals safely by wearing
gloves, if necessary. In the event of skin or clothing contamination by reagents,
etc., your instructor or teaching assistants (TAs) will provide first aid, so raise
your hand immediately to let them know. If a white coat or protective goggles
are required, it will be announced in the guidance including how to obtain them.
In addition, dispose of the chemicals in an appropriate manner following the
instructor's instructions.

54

3. Handling of Individual Equipment and Instruments Used inLaboratory in Biology
Microscopes
In Laboratory in Biology, each person often uses one microscope individually forobservation. Because microscopes are used by several faculties day after day,the utmost care must be taken to prevent breakdowns. If you notice any problems
with the microscopes, notify your instructor or TAs immediately. The microscopes
are stored in storage boxes in a dedicated locker, and the boxes must be carried
to each student's lab testing bench when used. Since the microscopes are quite
heavy, care should be taken when taking them out from the locker (especially for
those who use the microscopes stored in the upper section), and the bottom of
the box containing the microscopes should be held firmly with both hands whencarrying them. Do not use the handles on the top of the storage box, as they may
come off. Also, since the microscopes are precision instruments, take care toprevent vibration and shock because they are vulnerable to them. Detailed usage
instructions will be given at the beginning of the course, so be sure to understandthem very well and be careful not to handle the microscopes incorrectly. At theend of the experiment, make sure that no glass slides remain on the microscope,and return it to the locker in the designated method.

RazorsRazors for preparing samples for microscopic observation will be provided at the
beginning of the class and collected at the end. Razors must be placed in thedesignated container when collected. Razor blades are extremely sharp, so
accidents such as cutting fingers can easily occur. Use razors only whennecessary, and always keep them visible even when not in use. Handle them with
sufficient attention.

Cover Glass and Slide Glass
The cover glass used for microscopic observation is an extremely thin glass plate,
18 mm square and 0.15 mm thick, and is easily broken. Broken pieces of glass caneasily injure fingers and other parts of the body, and are extremely dangerous if
they enter the body. Therefore, it is necessary to handle it with sufficientattention. Since cover glasses and glass slides are disposable in Laboratory in
Biology, be sure to dispose of them in the designated containers after use, rather
than leaving them on the bench or the like.

55

Tweezers and Dissection Needles
Tweezers and dissection needles used in Laboratory in Biology have thin,pointed tips, so be careful not to bend them. Care should also be taken toprevent stabbing accidents.
Scissors
Scissors used for dissection will be provided by the university. As withmicroscopes, they will be used by several faculties in common, so be careful whenhandling them. Care must also be taken to prevent injury. If an accident occur,
notify your instructor or TAs immediately.
GlovesFor safety reasons, plastic gloves should be worn during the dissection practicein Laboratory in Biology, even though animals uninfected with pathogenic
microorganisms should be used. The use of gloves will be explained in detailduring the practice. When disposing of gloves at the end of the practice,separate them from general waste and dispose of them in designated containers(for biohazardous waste). Never mix them with general waste.
Paper, etc.
Paper used to wipe laboratory equipment and laboratory benches should not be
disposed of as general combustible waste, but in containers designated as noninfectious industrial waste. Paper on which a part of biological materials or
bodily fluids have adhered should be disposed of in containers designated as
infectious industrial waste.

Biohazard
A wide variety of biological materials are used in Laboratory in Biology. Although
we take care not to use materials that could cause biohazards such as bacterial
or viral infections, there is no such thing as sterile biological materials. There isno need to be overly afraid, but care must be taken to wash hands after eachexperiment. As mentioned earlier, eating, drinking, and smoking are prohibitedin the laboratories to prevent the ingestion of infectious microorganisms or
materials contaminated with hazardous reagents. The best way to prevent
accidents is to listen carefully to the instructor's warnings at the beginning ofclass and to follow them.

56

4. Precautions for Field Practice
Clothes
Since it is held on the Higashiyama Campus, it is considered that there is no
particularly big danger. However, it is necessary to dress appropriately foroutdoor activities (clothes easy to move, shoes easy to walk, etc.) and toprepare rain gear in case of rain. In the summer, measures against heat stroke
are also necessary. Only carry items necessary for the practice, and keep any
extra belongings in a designated area or locker.

Rash and Insect Bites
It is possible to get a rash from poison ivy or to encounter wasps, etc., so you
need to be careful. If you notice any danger, tell your instructor or TAs
immediately. And if an accident occurs, cooperate with them to deal with it.

57

Laboratory in Earth Science5

In addition to indoor experiments, outdoor practices are conducted in“Laboratory in Earth Science” . In order to conduct indoor and outdoor
experiments safely, please pay attention to the following points.

58

1. Introduction
Indoor experiments are mainly observations using naked eyes or microscopes anddo not involve any particularly hazardous works. However, the following points
should be noted.
Preparation for the Experiment
Read the textbook in advance to understand the contents and procedures of theexperiment. Also, be sure to follow the instructions given by your instructor. This
prevents most accidents caused by carelessness.
Clothing for Experiments
It is not specified in particular. Wear what is suitable for each experiment.
Depending on the content of the practice, clothes might get dirty by rocks andminerals, so wearing a white coat is recommended.

Organizing the Laboratory
On the laboratory desk, place only the items necessary for the experiment, suchas laboratory equipment and writing instruments, in a place where they will not
fall on the floor. Personal belongings should be put in a place designated by yourinstructor. After the experiment, clean the desk and the floor.

59

2. Precautions for Field Practice
What is Field Practice?
The field practice conducted in Laboratory in Earth Science is a field learning inwhich students visit where rocks appear on the earth's surface(outcrops) andobserve the production of various types of rocks and strata, as well as theminerals and fossils that make them up. Most of the locations where the fieldpractice for Laboratory in Earth Science are conducted are in hilly or low
mountainous areas near Nagoya. Outcrops are located along roads, cliffs indeveloped areas, beaches, and river banks.
Clothing for Field PracticeIn order to conduct outdoor practice safely, first of all, it is necessary to pay
attention to the clothes when participating. Clothing should be of sturdy fabricand suitable for exercise. Choose clothing with less skin exposure for both the
top and bottom. Footwear should be suitable for use on rough road (no heels or
sandals). A hat should be worn to protect your head from the sun. Put personal
belongings in a backpack or daypack so that both hands are available for work.
Keeping both hands free is effective in preventing danger and reducing injury.

60

3. Dangers in Field Practice
When practicing outdoors, you may encounter a variety of dangers. Although theprobability of actually encountering these dangers is not very high, it is important
to know what kind of danger exists. Dangers encountered during field practice canbe divided into those that are specific to Laboratory in Earth Science practice andthose that are related to field activities in general.

Dangers Specific to Laboratory in Earth Science Practice
Accidents Caused by Falling Rocks from Cliffs and Other Outcrops
Rockfalls can occur without warning. It is difficult to escape from falling rocks
after they occur. Therefore, it is important to stay away from cliffs where falling
rocks are likely to occur. The likelihood of a rockfall depends on the shape of thecliff, the type of rock that makes up the cliff, and the degree of weathering of
the rock. For example, a cliff with an overhang at the top, a cliff with weatheredrocks that are in tatters, or a cliff with many rocks lying at the bottom of thecliff (a cliff that has had many rockfalls) should be considered dangerous.
Accidents Due to Falls and Tumbles on Outcrops with Poor Footholds
When working around outcrops, different level of care should be taken thanwhen walking on a normal road. Helmets should be worn when working aroundoutcrops to reduce damage in the event of accidents such as falling rocks orfalls.
Loose Rocks
A stone that is lying in an unstable state. If you put your foot on it, you may lose
your body balance and fall over.
Riverbanks and Seashores
Wet stones are slippery. Especially those with moss or algae on them are, so
extreme caution is required when walking in such areas.
Slopes and Cliffs
It is not advisable to climb up to see the rocks above you. The danger of slippingand falling is more likely to occur to inexperienced people.

61

Use of Hammers
A hammer is used to break rocks and collect and observe rocks, minerals, andfossils, etc. Care should be taken to prevent bruising on the body from thehammer and injury from rock fragments scattered when the rock is broken(especially dangerous if they hit your eyes). You must take care not only ofhimself but also of those around you. When using the hammer, gloves (workgloves) should be worn to prevent cutting hands with broken rocks, andprotective goggles should be worn to protect your eyes.
Damage to Hammer
While using a hammer, damage may occur such as the handle breaking off, thehammer tip slipping off the handle (it is not abnormal for the hammer to comeloose toward the hand), or cracking (the hammer face cracking and chipping). If
such damage is found, notify your instructor in charge immediately. It isdangerous to use the hammer as it is.

62Dangers Present in Outdoor Activities in General
Traffic Accident
Be aware of traffic accidents during practical training. Depending on the courseof the field training, sometimes you may walk on busy roads with no sidewalks.
Sometimes you may have to walk on busy roads without sidewalks.
Sudden Illness
When participating in a field practice, students should prepare their physicalcondition for the day. However, even when you are supposed to be in perfectcondition, you may suddenly feel unwell during the practice. For example,
sunstroke, heatstroke, and sudden abdominal pain could occur. If you feelsomething wrong with your condition, do not overdo it and notify it immediately
to your instructor.

Bad Weather
In case of heavy rain, strong winds, lightning, swollen rivers, high waves, etc.,
the schedule of a practice may be changed or cancelled. Students should follow
the instructions of the instructor carefully.
Dangerous Creatures
Although there are many species of organisms that can harm us, the followings
are some of those that we may encounter in the Nagoya area. The degree of
danger varies from mild dermatitis to life-threatening. For information on how
to recognize these creatures, where they live, and what to do about them, refer
to "Dangerous Creatures in the Outdoors (Yagaini-okeru Kiken-na Seibutsu,
ISBN:9784582540123)" published by Heibonsha, edited by the Nature
Conservation Society of Japan (NACS-J).
Wild/stray dogs (yaken), pit vipers (mamushi), centipedes (mukade), certain
spiders (kumo), hornets (suzume-bachi) and other bees (black ones areaggressive, so wearing a hat to cover the hair on your head will have someeffect), moths such as poisonous moths (dokuga), land leeches (yamabiru),
horseflies (abu), blackflies (buyu), mites (dani), lacquer(urushi) plants, etc.
＊ There are many other plants and animals that are dangerous to eat, but they
are omitted here.
