Safety Awareness
Safety matters in the chemist’s professional work are regulated by numerous laws,
ordinances, directives and guidelines. However, safety awareness is based on solid
professional knowledge and hence can and must be learned and acquired just likeany other professional knowledge.

The Facts
85% of workplace accidents in laboratories and production plants were byhuman errors.
Ignorance of safety-relevant properties of substances or lack of insight into thetype of reactions performed often plays a role in this.
Habituation is contradictive to consciously safe work: Persons who havelong-term experience tend to neglect safety precautions and lost the initialrespect for a potentially hazardous method.
Consequently and regularly attend all safety briefings offered is the best
prevention.

Important goal of academic training of chemists/pharmacist:be proficient in safe and secure handling of chemicals
be able to protect both themselves and their colleagues and employees fromdangers,
act responsibly towards the environment and the general public,
identify possible dangers in the use of chemical products by consumers andprevent these dangers by providing proper instructions.

Important Conduct and Behavior in Laboratory
1.

Clothes in Laboratory
Put on / wear:
GoggleOverall (Lab. Coat) made of cotton, no Polyester fiber, in the case of fire,
the fiber will melt down and cause serious injury (The best way: complete
clothes are made of cotton)
Closed and protecting work shoe
Glove, especially if working with dangerous chemicals
No contact lens, esp. soft contact lens. Inclusion of solvents could cause
serious eye damages
No short trousers
But: The lab coat must not be worn outside the lab (lecture rooms, libraries,
cafeterias etc.)

Holding grips and touching switches only without glove

Note: Following completion of the lab work, the hands should be washedthoroughly with water and detergents gentle on the skin.
 For hands came into contact with chemicals or washed frequently,
regeneration-promoting skin cream is suggested.
 Due to danger of contamination, food anddrink may be neither stored nor consumed in Lab.
 Food and drink must not be stored in lab vessels or chemicals
containers.
 Neither may chemicals be stored in vessels usually used for holding
food and drink.
 Smoking is not permitted in a laboratory.

Transfer of Chemicals
Work in a fume hood (Hazardous Chemical)
Pouring out / Decanting of liquid Keep Etiquette position in upside position so that can always be clearly red.
This ensures also that adhering drops cannot damage the label when running
down the outside of the bottle.
 Do not put Stopper with under side on work surface
 The adherent drop can be removed with the stopper of the bottle after
decanting Use funnel
Do not transfer or store Flammable substances near thermal sources orelectronic instruments
Do not put low boiling substances under direct sunlight
Take Solid substances with spatula or spoon, if the quantity is large, use powder
funnelAttention! When Pouring out / Decanting of Chemicals
Any decanting of chemicals may cause danger of: Spilling, also upon skin and clothing Inhalation of vapours or dusts
 Formation of ignitable mixtures.

When working with Extremely or Highly Flammable Liquid, make sure that:
Liquid volume max 1 l
Keep closed the bottle
Keep away from heat source and flame
Do not be stored in refrigerator/freezer!
Note: Leakiness of bottle/container resulted in an explosive vapour-air mixture which can be ignited by
the switching spark of the thermostat of the refrigerator/freezer, resulting in a severe explosion followedby fire and considerable damage to property.

9. Self-igniting substances
Spontaneously ignite upon contact with air and/or water
Another sources for laboratory fires or explosions.
Alkali metals and their hydrides and white phosphorus are particularlycommon in lab. Practice

10. Potentially explosive substances and mixtures
Substances or mixtures of substances reacting violently upon exposure tothermal energy (heat, flames) or mechanical energy (friction, shock) and hence
release high energy and form high pressure result in very fast propagation ofshock waves.
Nitroso and nitro compounds, highly nitrated aromatic compounds (TNT, Picric
Acid), esters of nitric acid (GTN)
Compounds with N-N bonds (azo and diazo compounds, hydrazoic acid, azides)
Fulminates ( HCNO), NCl3, ICl3 and acetylides,

Peroxidic compounds (peroxy acids, peroxy esters, peroxides, hydroperoxides).

11. Working with peroxide forming substances
Attention! When During storage comes in contact with air, ether could form explosive
peroxide. This could be concentrated, e.g. by distillation. To prevent explosion, pay
attention the following information:
Store in a brown bottle, protect solvent from sun light exposure
Always full, this to minimize contact with air
Add KOH. KOH and peroxide form non soluble salt and hence can be separated
from solvent
Purified by Chromatography (Al-oxide), separation of peroxide
Prior use, tested with peroxide test kit

12. Working with Carcinogenic, Mutagenic, and Reproduction toxic
Substances (CMR)
When working with CMR substances, pay attention to the following information:
If possible do not use (e.g. Benzene substituted by Toluene)
Protection: lab. Overall and masker
Working only on fume hood
Do not leave the work place
Correct disposal

13.

Cleaning and Disposal
When disposing chemicals or cleaning apparatus, make sure that:
Dispose chemicals according to SOPNever dispose organic substances into lab. Sink
Calculate exactly the chemicals needed

SOP No. 002/SF-ITB/2015

Page 22 of 27

In the case of organic liquid: collect in a special container
Solid substances must be collected separately
When cleaning glassware, there is danger of contamination with more or lessunknown substances, e. g. by-products of a synthesis
Safe and expedient cleaning must be done
Immediately clean contaminated vessels or other equipment. Do not allow
residues to stand in vessels for a long time.
When cleaning, wear protective gloves and goggles. Beware of glass breakage
and injury by cutting during mechanical cleaning. Remove grease using a paper
towel and PE/Acetone if required.
Flush residual chemicals from the vessels using suitable and non-toxic solvents(e. g. acetone, ethanol). Dispose of the rinsing fluid as special waste (See SOP)
Do not put on with solvents rinsed equipment into the drying cabinet (oven) for
dryingAggressive/corrosive cleaning agents (e. g. concentrated nitric acid,concentrated sulphuric acid) may only be applied if other cleaning agents havebeen found ineffective.
Dichromate-sulphuric acid may only be applied exceptionally. Before usage,
make sure that the residual contents of the vessels cannot lead to hazardous
reactions with the cleaning agent.
Only after pre-cleaning as described, cleaning with commercially available
detergents is performed.

First Aid in case of chemical accidents
In the case of accidents, pay attention to the following conducts:
Rescue injured or poisoned persons from the danger zone, paying attention toself-protection.
The place for fist aid should be selected so that immediate transport off to thehospital is possible and no further helpers need to enter the danger zone.
The First Aider must protect himself/herself if required (protective gloves, acidprotection suit, respiratory protection etc.)
Call Emergency Department of Hospital (e.g. Borromeus or Hasan Sadikin
Hospitals): Notify emergency medical services and stated in the emergency callthe following information: WHERE has it happened?
 WHAT has happened?
 HOW MANY people affected/ injured?
 WHICH kinds of injury?
 WAIT for further enquiry!
Organize the transport to hospital Direct the crew of the ambulance car before the building and into it.
 Clear transport routes for affected/injured persons.
