Section 3 Hazard Identification (Also see
section 11)

Heat, shock, friction, or contact with other materials may cause
fire or explosion. Harmful if swallowed. Avoid breathing vapor or
dust. Use adequate ventilation. Avoid contact with eyes, skin or
clothes. Wash thoroughly after handling. Keep
closed.

Section 4 First Aid Measures

Heat, shock, friction, or contact with other materials may cause
fire or explosion. Harmful if swallowed. Avoid breathing vapor or
dust. Use adequate ventilation. Avoid contact with eyes, skin or
clothes. Wash thoroughly after handling. Keep closed.

FIRST
AID: CALL A PHYSICIAN. SKIN: Remove contaminated clothing. Wash
exposed area with soap and water.

EYES: Wash eyes with plenty
of water for at least 15 minutes, lifting lids occasionally. Seek
Medical Aid. INHALATION: Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give
oxygen

INGESTION: If swallowed, induce vomiting immediately
after giving two glasses of water. Never give anything by mouth to
an unconcious person.

Section 5 Fire Fighting Measures

Fire Extinguisher Type:

Any means suitable for extinguishing
surrounding fire

Fire/Explosion Hazards:

Thermal decomposition produces highly toxic
fumes. Strong oxidizer. Contact with combustible materials may
cause fire.

Fire Fighting Procedure:

Wear self-contained breathing apparatus and
protective clothing to prevent contact with skin and clothing.
Use water spray to cool exposed
containers.

Section 6 Accidental Release Measures

Wear Protective equipment. Sweep up, place in a bag and hold for
waste disposal.

Section 7 Handling and Storage

Store in a cool, dry, well-ventilated place away from
combustible materials. Wash thoroughly after
handling.
