**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Harmful by inhalation and in contact with skin. Toxic if swallowed.
Irritating to eyes and skin. May cause sensitization by skin
contact. May cause cancer. May cause heritable genetic damage. Toxic
: danger of serious damage to health by prolonged exposure through
inhalation, contact with skin and if swallowed. Possible risk of
impaired fertility.Cancer suspect agent.Light sensitive.Air
sensitive.

Potential Health Effects
Eye:
Causes eye irritation. Acrylamide can be absorbed through the eyes
and overexposure will produce the signs and symptoms of neurotoxicity
described below.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Acrylamide is readily
absorbed through unbroken skin and can cause nervous system effects
(neurotoxicity). These effects can result from a single overexposure
but are more likely after repeated exposures to small amounts over a
period of days or weeks. Signs and symptoms of overexposure include
increased sweating of the hands and feet, numbness, tingling and
weakness in the extremities, unsteady gait and decreased reflexes.
If the exposure route is dermal, the symptoms may be preceded by
peeling and redness of the skin at the areas of exposure, normally
the hands and feet.
Ingestion:
Harmful if swallowed.
Inhalation:
Acrylamide tends to sublime (go directly from solid to vapor form)
which may lead to inhalation exposure. Acrylamide can be absorbed
through the lungs and overexposure will produce the signs and
symptoms of neurotoxicity described above.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
cancer according to animal studies. Adverse reproductive effects have
been reported in animals. Prolonged or repeated exposure affects the
nervous system.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Either acute or chronic exposure may lead to weak or absent
reflexes, positive Romberg's sign, loss of vibration and position
senses and numbness and tingling of the limbs. An early sign of
toxic effects is peeling of the skin of the fingertips.
Antidote:
Pyridoxine (vitamin B6), pyruvate, and N-acetylcysteine have been
used to reduce the toxicity of acrylamide in experimental studies,
but are unproven.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
Containers can build up pressure if exposed to heat and/or fire. As
in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Use water spray to keep fire-exposed containers
cool. Dust can be an explosion hazard when exposed to heat or flame.
Combustible solid. Approach fire from upwind to avoid hazardous
vapors and toxic decomposition products. Fight fire from maximum
distance or use unmanned hose holders or monitor nozzles.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Avoid generating dusty conditions.
Remove all sources of ignition. Isolate area and deny entry. Provide
ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Do not
get in eyes, on skin, or on clothing. Keep container tightly closed.
Keep away from heat, sparks and flame. Do not ingest or inhale. Use
only in a chemical fume hood.
Storage:
Keep away from heat, sparks, and flame. Do not store in direct
sunlight. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances.
Keep away from acids. Do not store near alkaline substances. Keep
away from polymerization catalysts. Should not be exposed to
temperatures above 122F (50C).

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Utilize a
closed system process where feasible.
