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

EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Contact with combustible
material may cause fire.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause respiratory failure. May cause circulatory system
failure. May cause hemorrhaging of the digestive tract.

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. Strong oxidizer. Contact with other material may
cause fire.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use water only!

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition.

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

Handling:
Wash thoroughly after handling. Wash hands before eating. Use with
adequate ventilation. Avoid contact with eyes, skin, and clothing.
Keep container tightly closed. Avoid contact with clothing and other
combustible materials. Avoid ingestion and inhalation.
Storage:
Do not store near combustible materials. Store in a cool, dry,
well-ventilated area away from incompatible substances.

**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Exposure Limits

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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
