The National Institute for Occupational Safety and Health
(NIOSH) recommends the following appropriate preventive
measures to reduce or eliminate the adverse health and
safety effects of physical, chemical or toxic gas exposures
to their workers. The OSHA (Occupational Safe Healthy
Association) also recommends the use of adequate fitting
respirators for the workers who are exposed to toxic fumes
that are immediately dangerous to life or health.
Under the NIOSH respirator decision logic, the most
protective respirators, i.e. a self contained breathing
apparatus equipped with a full face piece and operated in a
pressure demand or other positive pressure mode would be
selected for the firefighters, exposure to carcinogens,
entry into oxygen deficient atmospheres, in emergency
situations during entry into an atmosphere containing a
substance at a concentration greater than 2000 times the
NIOSH recommends and for an entry into IDLH (immediate
danger to life and health atmosphere).
Safety precaution tips towards occupational exposures to
chemicals and physical hazards for workers:
1. A general safety measure involves no eating, no
drinking or no smoking in the general areas where the
chemicals are being used.
2. Wear protective glasses to prevent your eyes against
contact with the chemical irritants.
3. Accidents involving Radiation hazards.
Since the majority of accidents involving the radioactive
materials occur in the facilities that uses these
materials, protect yourself if you are working in those
environments.
The risk of further radiation exposure occurs when:
1. The source of radiation is still present and active.
2. Radioactive material has spilled on the patient.
Before entering the involved area, put on protective
clothing and rubber gloves. If the materials have
spilled on your clothes, remove the clothing and wash
yourself thoroughly. The clothing should be stored in
radioactive waste containers.
If you are a factory worker involved with dealing hazardous
materials, understand and make yourself familiar with the
various toxicity of the materials and learn to protect
yourself as well as the process of decontamination.
The Chemical Manufacturers Association has established the
Chemical Transportation Emergency Center (CHEMTREC) in
Washington, D.C. and they can be contacted 24 hours a day
by calling a toll-free number 1-800-424-9300 regarding
information on any hazardous material.
In case an accident happens:
1. Remove yourself outside of the area and breathe fresh
air.
2. Brush off any solid material that may remain on your
body and clothes.
3. In case of chemical burn, flood the skin with water
then treat the burn area accordingly.
4. If accidental swallowing of toxic material has
happened, ask for immediate medical help, induce
vomiting and take activated charcoal as indicated.
5. There are four accepted methods of decontamination
that everyone should be aware of:
a. Dilution - means flushing the contaminated person
or equipment with water.
b. Absorption - the use of filters and chemicals to
absorb the hazardous material.
c. Chemical washes to neutralize the hazardous
material.
d. Proper disposal and isolation of the contaminated
materials.
A few further safety tips for personal protection:
1. Protect the airway by wearing appropriate mask or
respirator as indicated.
2. In case of emergency, evaluate the area and try to
get fresh air.
3. Prevent skin contact by wearing appropriate personal
protective clothing and rubber gloves. For protection
against frostbite, wear layered protective clothing to
prevent the skin from becoming frozen by contact with
the cold liquid or cold metal bottles. In case
frostbite develops remove the clothing, warm the
extremity in warm, heated water, elevate the area and
seek medical help.
4. Prevent eye contact by wearing protective glasses, avoid
using contact lens and in case of emergency, wash your
eyes thoroughly and ask for medical help.
