Definitions(1) Occupational accidents
Occupational accidents are work-related accidents that resulted in an employee’s injury, illness,disability, or death. To qualify for occupational accident compensation, the accident must haveoccurred in the course of duties as an employee of the University of Tokyo.
(2) Compensation
Various forms of compensation are paid for occupational accidents, such as payment in kindfor medical expenses, compensation for lost income, disability compensation, and survivor’s
compensation.

Special-circumstance Occupational Accidents(1) Accidents occurring during breaks
These accidents are eligible for compensation if they resulted from a fault in the facility or
managerial practices.
(2) Accidents occurring during business trips
Since business trips are considered part of an employee’s duties, these accidents are
generally eligible for compensation, provided that they did not result from the employee’s
private activities.

Commuting Accidents(1) Commuting accidents are accidents that occurred during commuting to or from work andresulted in the employee’s injury, illness, disability, or death. Although technically notconsidered occupational accidents, they are treated as the same for purposes of accident
compensation.
(2) Accidents that occurred while deviating from the commuting path are not eligible forcompensation. However, the following activities are considered exceptions.
① Purchasing of daily necessities, and similar activities② Attending job training, school courses (such as evening high schools), and other sucheducational programs③ Voting in elections, and similar activities④ Receiving a medical examination or treatment at a hospital or clinic, and similar activities

Filing for Compensation
Occupational accident insurance claims need to be filed with the local labor standards office by theemployee or a family member, along with a certificate of occupational accident issued by theadministrative office of the employee’s division. In principle, claims must be filed within two years of
the accident, or within five years if applying for disability or survivor’s compensation.

Laboratory Safety: General Rules
Basic Safety Management
Be familiar with the hazards posed by the materials and equipment used in the laboratory, and withthe pertinent safety regulations. Refer to material safety data sheets (MSDS), which are an effective
tool for safety management. Also, consider replacing highly hazardous items with safer alternatives.
↓
Formulate safety measures to prevent hazards from becoming accidents.
↓
Conduct experiments and other lab work only when sufficient safety measures are in place.

Safety Rules for Experiments(1) Keep the laboratory in a tidy state.
(2) Do not leave an excessive quantity of chemicals on lab tables, and do not leave chemical
containers on the floor.
(3) Select goggles and other protective gear suited for the experiment.
(4) Keep a serious attitude when performing experiments.
(5) In principle, extremely hazardous tasks should not be performed at night or on holidays. Also,
conduct such tasks in a group, never alone.
(6) Prepare for accidents by familiarizing yourself with the locations of emergency exits, and thelocations, types, and operation of fire extinguishers.
(7) Whenever equipment must be left operating in an unattended laboratory, implement thenecessary safety measures and post emergency contact information on the room door or inanother highly visible location.
(8) Although university laboratories tend to be perceived as exempt from external laws, they arein fact subject to the same health and safety regulations that apply to the laboratories ofcompanies and other such organizations.
(9) Eating and drinking are not allowed in laboratories.

Laboratory Safety: Management of Hazardous Materials
Chemical Management System(https://utcris.adm.u-tokyo.ac.jp/CRIS_v1_0/index.aspx)
In the past, chemical management practices at the University of Tokyo varied by division andlaboratory. However, a university-wide system was established in 2006 to require the appointmentof a chemical safety manager for each laboratory to oversee the storage and amount of chemicals
used. The purpose of this system is to ensure that chemicals are handled properly in compliancewith the PRTR Act, the Poisonous and Deleterious Substances Control Act, the Fire Services Act,the Industrial Safety and Health Act, and other pertinent regulations.
The new system includes a computerized database to help laboratories to track their use ofchemicals specified by the Industrial Safety and Health Act, a task that used to be performed inquarterly surveys. Since certain chemicals are subject to restrictions on the amount that may be
stored in a particular building and area, make sure that your laboratory does not neglect to enter
data on chemical quantities.
This system can also be used for management of compressed gas cylinders at the Hongo Campus.
At the Kashiwa Campus, however, compressed gas cylinders are comprehensively managed at two
local storage facilities, so use the high-pressure gas management system of the Cryogenic Service
Laboratory at the Institute for Solid State Physics (see “Cryogens and High-pressure Gas” below).

Hazardous Materials
Below are common examples of hazardous materials, many of which are subject to regulations on
their handling and storage. Other materials that pose the same degree of hazard as these mustalso be handled under sufficient safety measures, even when not stipulated by law.
(1) Organic solvents: Types I–III (Industrial Safety and Health Act; Ordinance on Prevention ofOrganic Solvent Poisoning)(2) Specified chemical substances: Types I–III (Industrial Safety and Health Act; Ordinance on
Prevention of Hazards Due to Specified Chemical Substances)(3) Poisonous substances: Poisonous substances and specified poisonous substances(Poisonous and Deleterious Substances Control Act)
(4) Deleterious substances (Poisonous and Deleterious Substances Control Act)
(5) Dangerous substances: Types I–VI (Fire Services Act)
(6) High-pressure gases (High Pressure Gas Safety Act)
(7) Special-material gases (High Pressure Gas Safety Act)
(8) Biohazardous materials(9) Radioactive materials (see “Radiation and Radioactive Materials” below)
The materials listed above must be handled safely as indicated by your division’s safety manual.
Promptly dispose of unneeded chemicals in order to keep them from ending up as unidentified
substances.

13

Before Handling Hazardous Materials(1) Before handling a particular chemical, you must ascertain its toxicity (acute toxicity and chronic
toxicity, including carcinogenicity), flammability, explosiveness, and other such properties.
Refer to the MSDS provided by the supplier.
(2) Before handling a particular chemical, you must check whether it is subject to regulations.
When statutory procedures are required, complete the necessary procedures after consultingwith the Environment, Health & Safety Office.
(3) When planning an experiment involving a material that is highly hazardous (due to toxicity,
flammability, explosiveness, etc.), strive to minimize its use by thoroughly assessing thenecessity of the material, the availability of safer alternatives, and other such considerations.
(4) Safety management for chemicals is to be implemented under the leadership of eachlaboratory’s chemical safety manager. In particular, materials regulated by the Ordinance on
Prevention of Hazards Due to Specified Chemical Substances or the Ordinance on Preventionof Organic Solvent Poisoning in the Industrial Safety and Health Act must be handledappropriately as stipulated by the relevant law. These materials must be handled underdetailed safety management, including the implementation of workplace environmental
monitoring and specialized health exams for workers.

Rules for Handling Hazardous Materials(1) Handling and transport of hazardous materials must be performed only by personnel with
sufficient knowledge of the materials. In principle, administrative workers and other personnel
who have not received training in hazardous materials handling should not be allowed tohandle those materials.
(2) Before using hazardous materials, consider measures to prevent fires and accidents, and takeall necessary precautions. Personnel handling materials that pose a risk of fire or explosion
must wear protective masks and heatproof clothing, and have fire extinguishers close at hand.
Those handling materials that pose a risk of poisoning must wear protective masks, protective
clothing, and other necessary safety gear.
(3) Guard against splashing, scattering, leakage, and loss of hazardous materials. Use only
sturdy containers with lids or stoppers to ensure that the contents do not spill, leak, seep, or
evaporate.
(4) Open-flame heaters must not be used in laboratories that use volatile solvents.
(5) Know the location of fire extinguishers, and have them close at hand when performing tasks
with a risk of fire.
(6) Be sure to close the main gas valve before leaving a room unattended.
(7) Before conducting a hazardous experiment, inform everyone in the vicinity and take thenecessary safety precautions.
(8) When working with hazardous materials, use only the minimum amount necessary. Whenusing a material with unfamiliar properties, conduct a preliminary test on it.
(9) When opening a glass ampoule containing a hazardous liquid, hold it inside a large container
to guard against splashing.
(10) The lids/stoppers of reagent bottles can become difficult to open as they age. If it is necessary
to open such a bottle using a wrench or other tool, place a cloth or other soft material between
the bottle and tool to prevent the bottle from breaking.
(11) Do not dispose of hazardous materials together with general waste. Follow the specified
procedures for chemical disposal.

14

Rules for Storing Hazardous Materials(1) When storing large amounts of hazardous materials, separate them by class and store them inthe proper facility as prescribed by law. Poisonous and deleterious substances must be stored
in locked chemical cabinets.
(2) Always close the lids/stoppers of chemical and liquid waste containers.
(3) Regularly check the storage conditions and amount of hazardous materials in your custody,
and implement the necessary measures for ensuring health and safety.
(4) Generally, store hazardous materials in cool, shaded places away from open flame and otherheat sources. Also, do not mix different materials for storage.
(5) Implement the safety measures needed to prevent containers from breaking as a result of
falling, toppling, or colliding during an earthquake. Also, store different chemicals in separate
locations when there is a risk of fire or explosion due to spilling or mixing in an earthquake.
(6) Loss or theft of hazardous materials may result in serious consequences, so be sure to report
all such incidents to the materials manager.

Material Safety Data Sheets
Below are the types of information included on MSDS. Information marked with an asterisk must be
known by personnel who handle the material.
(1) *Name of material and supplier(2) *Composition, ingredients(3) *Hazard summary(4) *First aid measures(5) Firefighting measures(6) *Measures for responding to leaks(7) *Precautions on handling and storage(8) Measures for protection and preventing exposure(9) *Physical and chemical properties(10) Stability, reactivity(11) *Hazardousness(12) Environmental impact(13) Precautions on disposal(14) Precautions on transport(15) Applicable laws(16) Other information
MSDS can be obtained from the material’s manufacturer or distributor. (http://www.siyaku.com/)15

Laboratory Safety: Hazardous Operations(1) Implement sufficient protective measures and use extreme caution when handling equipment
involving high temperature, high pressure, high voltage, high speed, or heavy weight.
(2) When handling equipment with which you have little experience, carefully prepare for its use
and, if possible, check all parts. Those using equipment for the first time must receive
instruction beforehand from an experienced person.
(3) Equipment requiring proficiency to operate should be handled only after undergoing training inbasic operation, as unskilled use may result in a serious accident.
(4) Always check equipment carefully after use. If any disorder is found, fix it or ensure that thenext user is aware of the situation.
(5) Try to minimize noise, vibration, odors, and other nuisances in your work environment, suchas by improving work processes through the selection of low-vibration devices/tools and otherequipment that does not release high levels of harmful energy.
(6) Always maintain protective gear in optimum condition, and inform all workers of the gear’s
location.
(7) Make sure that all workers fully understand how to use protective gear, and provide them withtraining in proper usage when necessary.
(8) Make sure that protective equipment is disinfected and stored in a clean location after use.

16

Laboratory Safety: Environmental Safety
All campus members involved in educational and research activities need to implement safetymeasures to prevent those activities from having negative effects on the environment within andoutside the university.
(1) The Environmental Science Center leads efforts to minimize the university’s waste output andensure safe disposal. Properly dispose of waste materials in accordance with the Center’s
instructions.
(2) Disposal of chemicals considered harmful must be performed properly, even if the chemical is
not a regulated substance.
(3) Waste materials from medical activities and experiments involving living organisms must beprocessed properly at the source.
(4) Large volumes of sewage, garbage, and paper waste are generated on campus on a daily
basis. Constantly strive to reduce that output and consider measures for addressing theunderlying causes of waste generation.
(5) Actively pursue measures for conserving resources and energy, such as by sorting waste into
recyclable categories (paper, metal, bottles, etc.) and by developing disposal methods that canrecycle liquid waste, waste reagents, etc.
(6) Chemicals that have lost their labels or otherwise become unidentified pose a threat to safety
and entail enormous effort and costs for disposal, so make sure that all chemicals remain
readily identifiable. This can be done by properly managing chemical supplies and waste withan inventory control system, promptly disposing of unneeded chemicals, and keeping
chemical purchases to the minimum amount necessary. Also, chemicals often become
unidentified when kept in sample containers, so be sure to promptly label such containers anddispose of their contents once they become unneeded.

17

Laboratory Safety: Radiation and Radioactive Materials(1) Radiation and radioactive materials must be handled properly in accordance with the division’sradiation safety rules.
(2) Radiation and radioactive materials must be handled only in authorized radiation-control areas.
(3) The fundamental principle for using radiation and radioactive materials is that the resulting
benefits must outweigh the risks involved.
(4) Those who wish to handle radiation (X-rays) or radioactive materials must first register inaccordance with their division’s radiation safety rules, undergo the training seminars held by
the university and their division, and receive a specialized medical exam.
(5) Those planning to use X-ray diffraction equipment or other such devices must complete thenecessary X-ray operator procedures and comply with the instructions of the X-ray operation
supervisor or the person in charge of the equipment in question (safety management isconducted in accordance with the Ordinance on Prevention of Ionizing Radiation Hazards).
Management of synchrotron radiation facilities is regulated under the Radiation Hazard
Prevention Act, so those planning to use such facilities need to register as radiation handlers
under the same procedures for radioactive material handlers.
(6) In the event of an emergency, notify the laboratory supervisor and the on-site person in charge,
and contact the division’s radiation safety manager.
(7) Those who wish to use radiation facilities in other university divisions will need to present
certification of their registration as radiation handlers. To obtain a certificate, contact yourdivision’s radiation management office.

18

Laboratory Safety: Cryogens and High-pressure Gas(1) Cryogens (liquid nitrogen, liquid helium, etc.) and high-pressure gas must be handled properlyin accordance with the Kashiwa Campus high-pressure gas management manual and theKashiwa Campus rules on compressed gas cylinder handling.
(2) Those who wish to use cryogens or high-pressure gas must first undergo the training seminar
held by the Cryogenic Service Laboratory (Institute for Solid State Physics) under the High
Pressure Gas Safety Act. For details contact the Laboratory or visit its website at
http://www.issp.u-tokyo.ac.jp/labs/cryogenic/.
(3) When using cryogens indoors, keep the room ventilated and take other steps to prevent
asphyxiation. The use of an oxygen analyzer or other such safety devices is strongly
recommended.
(4) When handling cryogens, take care to prevent frostbite, such as by wearing protective gloves.
In case of minor frostbite, treat the affected area by immersing it in lukewarm water. In serious
cases, immediately seek medical attention.
(5) When handling high-pressure gas, take care to prevent explosions and other hazards. Notethat sudden opening or closing of high-pressure gas valves can lead to accidents.

Acrylamide Use and Workplace Environmental Monitoring
Acrylamide is classified as a Type II Substances by the Industrial Safety and Health Act (ISHA), andis one of the most frequently used ISHA-specified chemicals at the University of Tokyo. The ISHA
requires organizations using Type I and Type II Substances to carry out workplace environmental
monitoring and have the relevant personnel receive specialized medical exams. Acrylamide cancause skin disorders, neural damage, cancer, and other adverse health conditions. Generally, thelevel of these risks is considerably higher when acrylamide is used in powdered form, as opposedto gels or solutions. For this reason, all laboratories must observe the following rules regarding
acrylamide use.
1. Always strive to use commercially available acrylamide gels or solutions. Use powdered
acrylamide only when special circumstances necessitate its use.
2. When using powder acrylamide (including the making of acrylamide solutions), be sure to record
the amount of acrylamide used in the chemical use management log. Should the record alreadyinclude the data of acrylamide solution, please note this fact in the comment column.

25

Handling of Explosive and Ignitable/Combustible Substances
1. General Precautions(a) Before handling any hazardous material, be sure to fully ascertain all risks that it poses,
including with regard to explosiveness (explosive limits), ignitability/combustibility (ignition point,
flash point), and toxicity (threshold limit value, lethal dose), and consult with an experienced
user. Also, take measures to minimize damage caused by the material in the event of an
accident. Material safety data sheets provide important hazard-related information, so obtainand read a copy of the MSDS issued for the material you plan to use.
(b) The following types of experiments require extra caution.
1. Operations and reactions involving unknown hazards
2. Operations and material handling involving multiple, diverse hazards
3. Experiments involving both ignitability/explosiveness and toxicity
4. Experiments involving reactions near hazardous thresholds (high pressure, high/low
temperature)(c) Comply with the following important instructions when performing any experiment.
1. Always wear safety glasses/goggles. Depending on the nature of the experiment, also use
other appropriate protective gear, such as gloves, face shield, respirator, wire mesh, andsafety screen.
2. Check the location of fire extinguishers. When performing an operation that clearly poses afire hazard, have fire extinguishers close at hand.
3. If your eyes or skin come into contact with a hazardous chemical, immediately flush theaffected area with water for more than 15 minutes and, if necessary, seek medical
attention.
4. Close the main gas valve before leaving the room unattended.
5. Before disposing of a hazardous substance, take the necessary procedures to neutralize it.
(d) Before conducting a hazardous experiment, inform everyone in the vicinity and take thenecessary safety precautions.

2. Handling of Explosive and Ignitable/Combustible Substances
Depending on the ambient conditions, explosive and ignitable/combustible substances may cause
explosions or fires when exposed to heat, flames, shock, friction, contact with other chemicals, orother stimuli. For this reason, handling, storage, and disposal of such substances must be donewith extreme caution, based on full understanding of the hazards involved. The subsections below
provide examples of substances that pose explosion/fire hazards.
2.1 Explosive Substances
Substances that ignite or explode when subjected to heat, flames, shock, or friction, such as:
chemicals with N-O, N-N, O-O, or O-halogen bonds; acetylene and its heavy-metal salts andhalogen derivatives; and heavy-metal salts of oxalic acid (see Appendix 1 p.29 - p.31). The
following precautions must be observed when handling these substances.
(a) Do not handle explosive compounds/mixtures in large quantities.

26

(b) Exothermic reactions may become uncontrollable. Use sufficient caution to avoid this hazard.
(c) Do not use metal spatulas or glass stoppers to handle explosive compounds/mixtures, sincethese utensils can be a source of shock or friction.
(d) Follow the same precautions prescribed for flammable/combustible substances.
2.2 Flammable/combustible Substances
Substances that do not ignite simply from exposure to air, but readily ignite in the presence of anignition source. Flammable substances include ethers, carbon disulfide, acetone, hexane, benzene,
and ethanol. Combustible substances include hydrogen, carbon monoxide, methane, ethylene,ammonia, and other combustible gases. The following precautions must be observed whenhandling these substances.
(a) Take care to prevent accidental release of the gases/vapors of these substances.
(b) Know the flash point, ignition point, explosive limits, and other properties of these substances.
(c) Keep ignition sources away from these substances. Ignition sources include open flames (gastorches, etc.), electrical sparks, red-hot objects, and burning cigarettes.
(d) Before processing glass containers holding these any of substances, be sure to purge themwith air, nitrogen, or water vapor.
(e) Check the location of fire extinguishers. When performing an operation that clearly poses a fire
hazard, have fire extinguishers close at hand.
(f) In general, solvent vapors are heavier than air and hence tend to spread across the floor.
Consequently, even ignition sources located far away may cause the vapors to ignite or
explode, so always be aware of this hazard.
(g) In many cases, the vapor in the upper space of solvent containers is within its explosive limits.
Be sure to keep the containers tightly sealed, and be especially cautious of ignition sources
when dispensing small amounts of the solvent.
(h) When distilling or refluxing flammable solvents, make sure that an adequate flow of coolingwater is maintained and exercise caution regarding chemicals/equipment in the vicinity.
(i)

Ether and other volatile solvents should not be stored in the laboratory for long periods.

2.3 Pyrophoric Substances
Substances that readily generate heat or ignite when exposed to air, such as: organolithium,organoaluminum, yellow white phosphorus, reduced nickel, reduced palladium, silane, andphosphine. The following precautions must be observed when handling these substances.
(a) These substances can ignite upon contact with air, so handle them only in a nitrogen- or argonfilled glove box.
(b) These substances can ignite solvents, so do not place solvents in their vicinity.
2.4 Water-reactive Substances
Substances that generate heat or ignite upon contact with water, such as: alkaline metal, metal
hydride, metal carbide, and organometallic compounds. The following precautions must be
observed when handling these substances.
(a) Take care to prevent these substances from coming into contact with moisture or skin.
(b) Have dry sand on hand.
(c) Before disposing of these substances, take the necessary procedures to neutralize them.

27

2.5 Hazardous Mixtures
In some cases, mixtures of two or more chemicals pose a greater degree of hazard than posed byeach chemical alone. Hazards include the formation of products that are toxic or corrosive, and therisk of fire/explosion. This section focuses on the latter hazard.
Appendix 2 lists chemicals that, when mixed with certain other substances, readily generate heat,
ignite, or form ignitable/explosive substances. Examples of combinations that readily generate heator ignite upon contact include mixtures of oxidizing substances (sodium peroxide, chromium
anhydride, potassium permanganate, calcium hypochlorite, etc.) and combustible substances, andmixtures of oxy-halogen acid salts (potassium chlorite, potassium chlorate, potassium bromate,etc.) and strong acids (concentrated sulfuric acid, etc.). Although not listed, pyrophoric/waterreactive substances (chemicals that generate heat or ignite upon contact with air or water) are alsochemicals that pose mixture hazards.
In order to prevent the accidental mixture of incompatible chemicals, one must become familiar withthe combinations of chemicals that pose mixture hazards, and safely handle those chemicals duringexperiments. Also, it is important to implement measures to prevent fires resulting from theinadvertent mixture of chemicals during an earthquake. This includes taking steps to keep chemical
containers from falling and rupturing (such as by anchoring storage cabinets or installing toppleproof cabinets), and planning a safe storage layout that avoids the potential for fires in the eventthat chemical containers release their contents.
Note that Appendix 2 is not an exhaustive list, as there are innumerable possible combinations ofchemicals. Consequently, never assume that combinations not included in Appendix 2 are harmless.
Before working with an unfamiliar combination, be sure to look up information on its hazards inBretherick's Handbook of Reactive Chemical Hazards and other resources. The chemical hazard
information in this manual was compiled with reference to the 2003 edition of the University ofTokyo Faculty and Graduate School of Engineering’s safety manual.

35

Protective Eyewear
As centers for research, universities use a wide variety of chemicals generally not used foreveryday purposes, including many substances that are toxic or corrosive. These substances pose,
among other hazards, a risk of injuring the eyes, which are highly susceptible to chemical irritation
due to their moist, mucus-membrane surface. In many cases, even minor eye damage can cause
acute pain, and injury of the cornea can easily result in vision impairment. Because of these risks, itis necessary to protect the eyes when handling chemicals. Accordingly, the University of Tokyorequires all employees and students to wear protective eyewear (safety glasses/goggles, etc.)
when handling chemicals.
Other sources of eye injury include dust and flying debris. For example, perforation of the eye byiron-containing fragments can result in siderosis bulbi, a condition in which iron reacts adverselywith eye tissues, sometimes leading to a permanent loss of vision. Consequently, protective
eyewear must also be worn when performing tasks that can produce dust, flying metal fragments,
or other eye hazards. In addition, those who risk exposure to laser beams used in experiments are
required to wear laser safety glasses.

1. Examples of eye injuries(Source: Japan Industrial Safety and Health Association, An Illustrated Guide to Occupational Diseases)

A wire fragment from a wire brush became
embedded in this shipyard worker’s eye during
rust removal work.

An iron fragment became embedded in the lensof this eye, but the worker did not seek medical
attention for two months, despite noticeable
impairment of vision. The injury has been
complicated by a cataract (clouded area).

36

This eye was injured by caustic soda one month
before the photo was taken. The cornea has opacified
and the anterior chamber is hemorrhaging.

This photo, taken soon after the accident, shows an
eye that has suffered chemical burn from exposure to
cement dust. The cornea has opacified. (Stained withfluorescein.)

Condition of the eye 112 days after the accident. The
cornea remains opaque and an ulcer has formed.
Blood vessels have invaded the cornea.

Condition of the eye 15 months after the accident. The
cornea continued to be afflicted with recurrent

2. Types of protective eyewear
Safety glasses
These have the same shape as regular
eyeglasses, except that they feature sideshields to prevent flying materials fromentering from the side.

Fit-over safety glasses
This type can be worn over regular
eyeglasses.

Safety goggles
This type fully shields the eye area. Gastight models also provide protection
against vapors and gases.

3. Other requirements
Although corrective eyeglasses offer some protection from debris flying from directly in front of theeyes, they do not guard against debris approaching from oblique angles. As such, eyeglass
wearers need to protect their eyes by also wearing fit-over safety glasses. Also, those who risk
exposure to laser beams must use protective eyewear suited to the wavelength of the laser. For
further information on protective eyewear, refer to the following resources on the Division forEnvironment, Health and Safety website.

Step Ladder Safety
Sufficient caution must be exercised when using step ladders. This point was stressed at an
accident prevention seminar hosted by the Chuo Labor Standards Inspection Office in May 2005.
As reported by the instructor, many workers have suffered bone fractures and other injuries fromfalling off step ladders, and in one case a fall of just one meter resulted in the worker’s death. Such
accidents have also occurred at the University of Tokyo—in 2004, a person broke a bone fromfalling off a step ladder, and in 2005 another person strained a lower leg muscle when stepping off
a ladder. Because of these hazards, those using step ladders are required to observe the following
precautions.
Step ladder precautions(1) Never work alone when using a step ladder. While on the ladder, have at least one person holdit to prevent falling.
(2) Position the ladder so that its legs are firmly planted on the ground.
(3) Never use a ladder if the spreader locks are damaged or corroded.
(4) Never stand on the ladder top or any parts other than the steps.
(5) Never hold too many objects when on a ladder, as doing so makes it difficult to maintain yourbalance.
(6) Also use caution when stepping off the ladder.
Step ladders and muscle strain
Leg muscle strain can result from skipping steps/rungs while descending a ladder. According tosports medicine experts, muscle strain occurs when a muscle tears from excessive eccentric
contraction. Muscle contraction in which the muscle shortens while generating force is referred toas concentric contraction. In eccentric contraction, a contracting muscle is subjected to elongationfrom a strong load on the joint. For example, when a person lands on his or her toes whiledescending from a higher point, eccentric contraction occurs in the gastrocnemius muscles (part ofthe calf muscles). Eccentric contraction also occurs when a person turns about or makes otherchanges of posture involving the application of force. Eccentric contraction is stronger thanconcentric contraction, and can injure the contracting muscle, especially when a twisting force isalso involved. This phenomenon is also the reason why descending a slope places greater stresson the knees than does ascending. Although it is all right to skip a step when climbing a ladder orstairs, you should take small steps when descending to avoid the risk of muscle strain.

Laser Safety
Those using laser devices must familiarize themselves with the following information on physicalhazards and precautions.
(1) Physical Hazards
The main physical hazards posed by laser beams are eye and skin injuries. In some cases, laser
radiation can cause major permanent damage, such as blindness from injury of the corneas. Also,laser damage to the front of the eye (cornea and crystalline lens) can result in cataracts and otheradverse conditions, and high-power lasers can also burn the skin. In particular, short-wavelength
radiation can cause photochemical reactions, so lengthy exposure should be avoided, even when
the beam is of low intensity. Below are important precautions for preventing physical harm.
Eye Hazard Precautions(a) When using a laser, always wear protective eyewear suited to the laser’s wavelength.
(b) Never directly look at a laser beam, even if it is of low intensity and you are wearing protective
eyewear.
(c) Before using mirrors or other optical instruments with a laser, make sure that they are firmly
secured.
(d) Do not place highly reflective objects in the vicinity of the laser. Do not wear a watch while
using a laser, as the glass face can reflect the laser beam (there have been accidents where
blindness resulted from reflected laser radiation).
(e) Avoid setting the laser beam path at eye level, including the level when walking or working.
(f)Whenever possible, use the laser in a well-lit place.

(g) Whenever possible, shield the laser beam path, including the area beyond its terminus, inorder to prevent unplanned reflection.
(h) Post appropriate warning signs on the doorway or safety partition of areas where lasers areused. Never place the laser device so that it is pointed at the doorway.
Skin Hazard Precautions(a) Never expose your body to laser radiation, including parts covered by clothing.
(b) Minimize the potential for exposure, such as by wearing long-sleeved, fire-resistant clothing.
(c) Never stand in or beyond the path of a laser beam.
(d) Never place flammable materials (solvents, oil, paper, etc.) in a laser beam path.
(e) Always use a purpose-built laser beam stopper or nonflammable shield (bricks, etc.) to provide
a safe terminus for the beam.
(2) Other Precautions(a) Lasers operate on high voltage, so never remove a laser device’s housing at any time, unlessabsolutely necessary (such as when repairs are needed). Before removing the housing, takeprecautions to prevent electrical shock.
(b) Always wear protective eyewear when a laser device’s housing is removed, even if a laser
beam is not being generated.
(c) Use additional caution when working with excimer lasers, as they use halogen gas. Be sure to40

check the gas piping for leaks, etc. and take other appropriate safety measures.
(d) The dyes used in some dye lasers are carcinogenic, so exercise additional caution when using
these lasers. Always wear protective gloves and eyewear when preparing dye solutions. Whenpossible, dye solutions should be prepared in a local exhaust ventilation system.
(e) When using a laser, take steps to ensure that unaware personnel can readily take notice thatlaser work is being performed.
Laser Classes
The level of hazard posed by lasers rises with the power output of their beams. Under the March 25,
2005 revision of JIS C 6802: Radiation Safety Standards for Laser Products, lasers were classified
by hazard level as follows.

A wide variety of electrical equipment is used on campus to enable the smooth, efficientperformance of experiments and other research activities. It must be remembered that even little
mistakes in the use of that equipment can result in electrical shock, short-circuiting, power outages,
and fires. Laboratory work in particular poses a high electrical hazard, as personnel must
sometimes repair electrical wiring/devices and perform tasks that place electrical systems under
extreme operating conditions. As such, all laboratory personnel are expected to acquire a basic
knowledge of electricity and a correct understanding of the rules for safe use of electrical facilities.
Regulations
Electrical facilities are subject to the Electricity Business Act, technical standards, and various otherregulatory controls. Under the Electricity Business Act, the electrical facilities at University of Tokyo
campuses are deemed Electric Facilities for Private Use, and each campus is required to have a
set of electrical safety rules and voluntarily carry out electrical facility construction work, inspections,operation, safety measures, and other responsibilities for compliance with technical standards. In
particular, the act requires the installation of electrical wiring and other such work to be done by aqualified electrician wearing protective gear, using the appropriate materials and methods. In theevent that a university member causes an accident through action in violation of such requirements,
the relevant supervisor and chief electrical engineer would be held responsible under both theIndustrial Safety and Health Act and the Electricity Business Act.
Electrical ShockPhysical Effects
Electrical shock occurs when an electrical current from a conductor flows through a person to theground or another conductor. It results from touching live, uninsulated parts of electricalwiring/devices or moving too close to an electrically charged component. The effects on the humanbody vary depending on such factors as the type of power source, the current path, and theduration of exposure, but in every case the amount of current is a big part of the equation. The
direct effect of amperage varies, but in general, currents at least around 100 mA are consideredlethal. However, even currents as low as 20 mA can be fatal—for example, grabbing a live
conductor at this amperage would cause muscle spasms and nerve paralysis that could prevent theperson from releasing the conductor, and hence lead to death.
Prevention(1) Never touch electrical equipment with wet hands.
(2) Promptly replace damaged power outlets, plugs, etc.
(3) Be sure to ground all electrical equipment. This is especially important for equipment that is
located near water, uses water, or has metal housing.
(4) Never place power strips or other such devices on the floor in laboratories where there ispotential exposure to water, metal shards, etc.
(5) Keep power outlets and electrical devices free of dust and grime.
(6) Capacitors can remain charged even after the power supply is switched off, so never touch a
circuit before completely discharging all capacitors in it.

42

(7) The live parts of high-voltage and/or high-amperage laboratory equipment must be insulated toprevent electrical shock, and the area surrounding the equipment must be designated as adanger zone off limits to unauthorized personnel.
(8) Never work alone when performing an experiment involving high voltages and/or strong
currents. Also, post appropriate warning signs around the work area, such as “Danger! High
Voltage.”
Short-circuiting Accidents
Over time, electrical insulation can degrade from exposure to heat and other stress, resulting in therisk of short-circuiting. The accumulation of dust or moisture inside electrical equipment often
results in short-circuiting, and can thus lead to a fire.
Prevention(1) Install a ground fault circuit interrupter at power sources with potential exposure to moisture.
(2) Promptly try to determine the cause of any abnormalities detected in electrical equipment, suchas strange sounds or odors.
(3) Regularly inspect and clean electrical devices to keep them free of dust and grime.
Fires from Overheating
Fires can result from overheating of electrical systems. Sources of overheating include heatemitting devices, overloaded electrical wiring, and bad electrical contacts.
Prevention(1) Fires from electrical overheating are often caused by electrical heaters/burners and otherheating devices, so exercise caution when using them. In particular, do not allow devices with
exposed heating elements to operate unattended.
(2) In general, heating devices draw a large current and are prone to overheating from bad
contacts between their plug and the power outlet. Consequently, it is important to regularly
check the electrical cords and outlets for damage or other problems.
(3) Whenever a high-temperature electric furnace is to be operated unattended for a long time,measures need to be taken to prevent fire hazards, such as by removing flammable objects
from the vicinity.
(4) Power strips overheat when overloaded, so avoid using them to power heating devices, sincesuch devices generally draw large currents.
Electric Sparks
Fires and explosions can result from the release of electric sparks in places where combustible
gases or vapors accumulate.
Prevention(1) Never place flammable/combustible materials near electrical switches, outlets, and other sparksources.
(2) When planning to use electrical switches and other spark sources in places where combustible
gases or vapors accumulate, select only devices with anti-explosion designs.

43

Precautions on Electric Cabling
Normally, the walls of laboratories and other work rooms have power outlets and, in some cases, apower distribution board. In general, outlets are rated at 15 A, so power will have to be drawn
directly from the distribution board in cases where the outlet capacity is insufficient, such as whenusing equipment that requires a heavy current.
Precautions(1) Consult with the facility supervisor and other relevant managers before carrying out electricalinstallation work in the laboratory/work room.
(2) When temporarily running electrical cabling across the floor, use cab-tire cables resistant tocompression, and secure them to the floor with duct tape or other appropriate means.
(3) Whenever possible, avoid cabling layouts that rely on plug strips to power multiple devices. If
this is not possible, use plug strips that have a thick cable and can be secured to the wall (notthe floor) with magnets, etc.
Responding to Electrical Accidents
Electrical ShockFirst, immediately switch off the power supply. When this is not possible, use an electricallyinsulated pole, a dry wooden pole, etc. to separate the victim from the electrical shock source. Next,
apply first aid to the victim and take other emergency procedures.
Electrical Fires
First, switch off the power supply and then begin firefighting efforts. When the power cannot be
turned off, avoid using water to fight the fire, as it may result in electrical shock and cause the fire to
spread. Instead, use a dry chemical extinguisher, a carbon dioxide extinguisher, or otherextinguisher designed for electrical fires.

Health and Safety Management Plan for Field
Educational/Research Activities
１．Plan and Responsibilities■The head of an educational/research unit (unit head) must submit a Health and Safety
Management Plan for Field Educational/Research Activities to their department in advanceof any such activities.
■Even if a student is to conduct field research alone and provided the research is for arequired subject, all parties must be aware that the framework for that research will be
conducted under the responsibility of the university president, managing director,
dean/director, department head, laboratory head, project head, and the student’s faculty
supervisor collectively. If an accident should occur because of deficiencies in the plan or in
the structure, responsibility extends from the supervisor to the entire university.
■The dean/director must confirm that every field research activity planned by any member ofthe department (faculty, students, researchers, and others) is conducted safely, that rules
and related laws/regulations are complied with, and that any deficiencies are rectified.
Depending on the situation, the dean/director may terminate the research.
■If field research is conducted under the guidance of a faculty supervisor, he/she is consideredas the unit head. This also applies when a student conducts a research alone. Therefore, thesupervisor must submit the Health and Safety Management Plan for Field
Educational/Research Activities to their department.
■If a unit head does not accompany students in their field research, the unit head must selectan assistant from participants, and have him/her be responsible for ensuring safety during
the research activity. The assistant should maintain close contact with the unit head, andreport such any execution of or changes in the plan, as well as reporting any and all
accidents.
■A student should not be allowed to conduct field research alone unless the unit head feels
confident that safety and close contact with the student will be maintained during the
research activity.
２．Submission■The unit head must prepare a plan including such information as location of the fieldresearch, schedule, lodging place, participants’ names and emergency contact details suchas home telephone numbers, means of transportation, measures for hazardous operations,
measures for local/environmental hazards, measures for legal compliance, and emergency
contact method. In addition, a detailed itinerary with an attached map, contact list of medical
institutions, police and fire stations, statement of whether insured or not, emergency contact
method for the unit head (if stays on campus), assumed date and time in case of requesting
for a search should be attached if necessary.
■The content of the plan should be informed to all participants by the unit head, and submitted
to the dean/director through the Environment, Health & Safety Office responsible for theirdepartment.

51

３．Procedures■In principle, the deadline for submitting a Health and Safety Management Plan for Field
Educational/Research Activities is one week prior to departure for research activities in Japan,
and 2 weeks prior to departure for research activities outside Japan.
■ At the same time of submitting the Health and Safety Management Plan for Field
Educational/Research Activities plan, inform all relevant people by e-mail (except
dean/director).
■Inform all relevant people of any changes in the plan by e-mail.
■The head of the Environment, Health & Safety Office or the Department Safety and Health
Representative confirms the health and safety management, requests the dean/director’s
approval, and then returns a copy of the approved plan to the unit head.
■Because of travel regulations, maintain close contact with the department administration
office.
■The original copy of the plan is stored at the Environment, Health & Safety Office, Kashiwa
General Administration Office (tel ext: 63585 or 63586; e-mail: anzen@kj.u- tokyo.ac.jp).
