artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.
SECTION 5. FIREFIGHTING MEASURES
General Information: As in any fire, wear a self-contained breathing apparatus in pressuredemand,
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. Runoff from
fire control or dilution water may cause pollution.

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.
SECTION 7. HANDLING AND STORAGE
Handling: Minimize dust generation and accumulation. Avoid contact with skin and eyes. Keep
container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation.
Storage: Store in a cool, dry place. Store in a tightly closed container.
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.
