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

EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.Light sensitive.Air
sensitive.

Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis.
Skin:
Causes skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver damage. May cause cardiac disturbances.
Inhalation:
Causes respiratory tract irritation. Can produce delayed pulmonary
edema.
Chronic:
Effects may be delayed. Chronic exposure may cause liver damage.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Do NOT induce
vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls
of milk or water. Wash mouth out with water. Get medical aid if
irritation or symptoms occur.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid if cough or other symptoms appear. Do
NOT use mouth-to-mouth resuscitation.
Notes to Physician:
Treat symptomatically and supportively.

**** 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.
Extinguishing Media:
Use agent most appropriate to extinguish 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:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Place under an inert atmosphere.

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

Handling:
Wash hands before eating. Minimize dust generation and accumulation.
Avoid contact with eyes, skin, and clothing. Keep container tightly
closed. Avoid ingestion and inhalation. Use with adequate
ventilation. Store protected from light. Handle under an inert
atmosphere. Store protected from air. Wash clothing before reuse.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not expose
to air. Store protected from light. Store under an inert atmosphere.

**** 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.
