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: Get medical aid. Flush skin with plenty
of soap and water for at least 15 minutes while removing contaminated
clothing and shoes. Wash clothing before reuse.
Ingestion: Do NOT induce vomiting. 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.

immediately. If breathing is difficult, give oxygen. Get medical
aid. Do NOT use mouth-to-mouth resuscitation.
Notes to Physician: Treat symptomatically and
5 - Fire Fighting Measures
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.
Non-combustible, substance itself does not burn but may decompose
upon heating to produce irritating, corrosive and/or toxic fumes.
Extinguishing Media: Substance is noncombustible;
use agent most appropriate to extinguish surrounding fire.
6 - Accidental Release Measures
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.
7 - Handling and Storage
Use with adequate ventilation. Minimize dust generation and accumulation.
Avoid contact with skin and eyes. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage: Store in a cool, dry, well-ventilated
area away from incompatible substances.
8 - Exposure Controls, Personal Protection
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.
