Safe Chemical Handling
Chemicals are all around us - in the food we eat, the clothes we wear, in
the products we use everyday. Chemicals can help us live better lives, but if we
don't understand about the chemicals we use, they can harm us.
This program is designed to help you understand more about chemicals and chemical
safety. It's important to be informed and aware of chemicals and chemical
safety. The first and most important step is to stop and read the label.
All the basic information you need to know is found on the label. It will tell
you the name of the basic substance, what types of hazards there are, what it
will do, what chemicals can't be mixed with this particular substance, and any
emergency medical information you will need to know. You will also learn how to
properly store, handle, and dispose of the material.
Once you've read the label you will be able to identify the type of chemical and
the proper instructions required for this chemical.
Basically, there are four types of chemicals.
l. Toxic agents :
These are chemicals that are poisonous to you, and can act upon the body very
rapidly. Hydrogen sulfide and cyanide are examples of toxic agents.
2. Corrosives :
This type of chemical is usually an irritant. Corrosives can damage your body by
burning, scalding or inflaming body tissues. Examples of corrosives are
chlorine, hydrochloric acid.
3. Flammables :
Flammables are the chemicals that burn readily. They may explode or burn if
sparks, flames or other ignition sources are present. Examples are gasoline,
benzene and ethyl ether.
4. Reactives :
Reactive chemicals are those that require stability and careful handling. Some
of them can explode or react violently if the container is dropped or hit. Other
reactives may react violently if mixed improperly with other substances.
Nitroglycerine is an example of a reactive chemical.
No matter what type of chemicals you are using, you need to be aware of the ways
that chemicals may affect you. If you are not properly protected, you may be
exposed to chemical hazards. Here are the ways in which chemicals can enter your
body:
Inhalation : Chemical vapors, dust or gases can be inhaled if you are
not wearing a respirator or proper respiratory equipment.
Absorption : Some chemicals can be absorbed right through your skin and
enter your body. You can prevent this hazard by wearing the appropriate gloves
and protective clothing.
Ingestion : You may be ingesting small doses of chemicals daily and not
even realize it. Chemicals can be absorbed by food, cigarettes and drinks. They
can also remain on your skin and be transferred to your food if you don't wash
your hands before eating. Always be sure to wash your hands before eating and
make sure you store food away from your work area.
Spillage : There is always a chance that you may be accidentally splashed
or exposed to a chemical. To prevent injury you should always wear the proper
protective equipment, according to company policy and the requirement of each
specific chemical.
Safe Handling Tips
1. Read the label :
It will tell you what you need to know about your chemical. If you find you need
more information, ask your supervisor for a copy of the material safety data
sheet. The MSDS gives more technical information about the chemical than the
label.
2. Dress the part :
Wear the proper safety protection, clothing and equipment as required.
3. Follow directions :
If the label says, use only with adequate ventilation, make sure you do so.
Never mix chemicals unless you've been trained and authorized by your company.
4. Know emergency procedures :
Be familiar with first aid procedures, and be sure to know where the emergency
eye wash showers are located; also know where emergency phone numbers are
posted.
5. Be careful :
Don't work alone; make sure there is someone there to help you if necessary.
Don't try to hurry or take shortcuts, you just can't rush safety. Chemical
safety is a job for professionals.
6. Report any suspected problems :
If you notice any malfunctioning equipment or any electrical equipment that is
in need of repair, report it to your supervisor immediately. Also report any
suspected problems with your chemicals, if the chemical odor is unusual, don't
use that chemical. It may have changed with time. Report anything unusual to
your supervisor.
7. Keep your work area neat, clean and organized :
You will know where everything is, and you will be able to work more
efficiently.
8. Store everything properly :
Make sure to close containers tightly. Keep flammables in a safe area, and use
only the smallest amount necessary for the job. Store compressed gas in
leak-free containers.
