Flash Point:No data available.
Extinguishing Media:regular dry chemical, dry sand, lime, soda ash
Large fires: Keep unnecessary people away, isolate hazard area and
deny entry. Let the fire burn.
Fire Fighting Procedures:Do not use water. Do not use foam. Move
container from fire area if it can be done without risk. Use
extinguishing agents appropriate for surrounding fire. Do not get
water inside container. Avoid inhalation of material or combustion
by-products.
Unusual Fire/Explosion Hazard:Severe fire hazard. May ignite on
exposure to air.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. Stop leak if possible
without personal risk. Do not get water directly on material. Small
dry spills: Collect material into suitable, loosely covered
container for disposal. Move containers away from spill to a safe
area. Small liquid spills: Absorb with sand or other
non-combustible material. Collect spilled material in appropriate
container for disposal. Large spills: Dike for later disposal.
Powder spills: Cover with plastic sheet or tarp to minimize
spreading and protect from contact with water. Keep unnecessary
people away, isolate hazard area and deny entry. Stay upwind and
keep out of low areas.

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. Store under an inert atmosphere.

other positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Provide local exhaust or process enclosure ventilation
system. Ensure compliance with applicable exposure limits.
