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

EMERGENCY OVERVIEW
May cause cancer. Possible risk of harm to the unborn child.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Low hazard for usual industrial handling.
Inhalation:
May cause respiratory tract irritation. Low hazard for usual
industrial handling.
Chronic:
May cause reproductive and fetal effects.

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

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Wash clothing before reuse. Flush skin with plenty
of soap and water. Destroy contaminated shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid.
Notes to Physician:

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

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. This
material in sufficient quantity and reduced particle size is capable
of creating a dust explosion. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. May form flammable
dust-air mixtures. Keep container tightly closed. Do not get on skin
or in eyes. Do not ingest or inhale. Wash clothing before reuse.
Storage:
Keep away from heat and flame. Store in a cool, dry place. Keep
containers tightly closed.

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

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR ??1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
