Good housekeeping, personal
cleanliness and equipment maintenance
are important wherever any
chemicals, including corrosives, are
used.
To maintain cleanliness and order at
all times in the workplace, the Canadian
Centre for Occupational Safety and
Health recommends the following:
Clean up any spills and buildups of
corrosives promptly and safely;
Properly dispose of unlabelled or
contaminated chemicals;
Remove empty containers at once
from work areas;
Ensure that all containers for waste are
properly marked and easily located.
Personal cleanliness is a very important way of protecting personnel working
with hazardous chemicals. CCOHS
also recommends:
Wash hands before eating, drinking,
smoking or going to the toilet;
Remove and clean contaminated
clothing before wearing it again, or
discard it;
Do not smoke, drink, chew gum or eat
in any areas where hazardous chemicals
are present;
Store food and tobacco products in
uncontaminated areas;
Avoid touching yourself with contaminated
hands;
Clean yourself thoroughly at the end
of the workday.
Regular maintenance of equipment is important in preventing leaks or emissions
of corrosives into the workplace.
Ensure maintenance personnel know
the possible hazards of the materials they
might be exposed to.
Be sure they know any special procedures
and precautions that might be
needed before they begin to work on
equipment.
Regular workplace inspections can help
in spotting areas where health and safety
problems may be developing.
When should I wear proper personal
protective equipment? If other methods,
such as engineering controls, are
not available or effective enough to
control exposure to corrosives, wear
suitable personal protective equipment
(PPE).
Choosing the right PPE to wear when
doing a particular job is essential. MSDSs
should provide general guidance.
Selecting PPE for a specific job is best
done with the help of someone who
knows how to evaluate the hazards of
the job and how to select the proper
PPE.
Avoid Skin Contact
Wear protective gloves, aprons, boots,
hoods, or other clothing depending on
how much chance there is of skin contact.
This clothing must be made of materials
that resist penetration or damage
by the chemical. The MSDS should recommend
appropriate materials. If it does
not, contact the chemicals manufacturer
or supplier for specific information.
Protect Your Eyes and Face: Always
wear eye protection when working with
corrosives. Although ordinary safety
glasses provide some protection, chemical
safety goggles are best. In some
cases, you should also wear a face shield
to protect your face from splashes.
Know and be familiar with the right
PPE for emergencies, as well as normal
operations. You must wear the PPE
needed for doing a particular job. PPE
cannot protect you if it is not worn.
What should I do in an emergency? Be
ready to handle emergencies safely. In
emergencies like chemical fires, leaks and
spills, act fast.
Evacuate the area at once if you are not trained to handle the problem or if it is
clearly beyond your control.
Alert other people in the area to the
emergency.
Call the fire department immediately.
Report the problem to the people responsible
for handling emergencies
where you work.
Obtain first aid if you have been exposed
to harmful chemicals.
The MSDS and container label for a
particular corrosive should give specific
first aid instructions in case of exposure
by skin or eye contact, inhalation, or
swallowing.
Most workplace injuries caused by
common corrosives, such as acids and
bases, result from accidental skin or eye
contact. The first aid for these injuries
usually involves flooding the contaminated
area with large amounts of water.
However, the specific first aid recommendations
can vary from one corrosive
material to another, depending on the
nature (properties and hazards) of the
material.
Emergency eyewash stations and safety showers should be present wherever accidental
exposure to corrosives might occur.
These are available from safety
equipment retailers.
Only specially trained people, equipped
with the proper tools and protective equipment,
should handle the emergency. Nobody
else should go near the area until it is
declared safe.
Planning, training and practicing for
emergencies are important so that
everyone knows what they must do.
The MSDSs for the materials you are
using on each job are a good starting
point for drawing up an emergency
plan. MSDSs have specific sections on
fire and explosion hazards, including
suitable fire extinguishing equipment
and methods, spill clean-up procedures
and first aid instructions. If the directions
in each MSDS section are not
clear or seem incomplete, contact the
materials manufacturer or supplier for
help. You can obtain help in developing
emergency plans from many other
sources too. Local fire departments can
assist with fire emergency plans and training. Specialized private consultants
are also available.
What are the basic safety procedures
concerning corrosives? Following these
basic safe practices will help protect you
from the hazards of corrosive materials:
Obtain and read the Material Safety Data
Sheets (MSDSs) for all of the materials
you work with;
Be aware of all of the hazards (fire/explosion,
health, chemical reactivity) of
the materials you work with;
Know which of the materials you work
with are corrosives;
Store corrosives in suitable labeled containers
away from incompatible materials,
in a cool, dry area;
Store, handle, and use corrosives in
well ventilated
areas;
Inspect containers for damage or leaks
before handling. Never use containers
that appear to be swollen;
Handle containers safely to avoid
damaging them;
Dispense corrosives carefully and keep
containers closed when not in use;
Stir corrosives slowly and carefully into cold water when the job requires mixing
corrosives and water;
Handle and dispose of corrosive wastes
safely;
Practice good housekeeping, personal
cleanliness and equipment maintenance;
Wear the proper personal protective
equipment for each of the jobs you do;
Know how to handle emergencies (fires,
spills, personal injury) involving the
corrosive materials you work with;
Follow the health and safety rules that
apply to your job;
Flush contaminated eyes or skin with
water for at least 20-30 minutes, sometimes
longer, in case of accidental contact.
Call immediately for medical
assistance;
Know where the closest eyewash station
and safety showers are located, and how
to use them;
Never return unused material to the
original container. It may contain traces
of contamination which may cause a
chemical reaction;
Do not reuse empty containers the
residue may be hazardous.
