SECTION IV - FIRE AND EXPLOSION HAZARD DATA:
Method Used: Explosive Limits: LEL: N/A UEL: N/A
Extinguishing Media: Use suitable extinguishing agent for surrounding material and type of fire
Special Fire Fighting Procedures:
Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire and Explosion Hazards: Solid will not ignite
SECTION V - REACTIVITY DATA
Wear appropriate respiratory and protective equipment specified in section VIII. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Dispose of in accordance with state, local, and federal regulations.
Store in cool, dry area and in tightly sealed container. Wash thoroughly after handling.
Local Exhaust: To maintain concentration at low exposure levels. Mechanical (General): Recommended.
Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.
