Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: High-pressure water jets may spread powder
Special Hazards: May release carbon oxides, nitrogen oxides under fire conditions
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Fire/Explosion Risk: Not highly flammable; fine dust may cause risk of combustion in air under specific conditions
Personal Precautions: Use personal protective equipment; avoid creating dust; ventilate area
Environmental Precautions: Prevent further leakage or spillage if safe; do not allow product to reach sewage systems or watercourses
Methods for Cleaning Up: Sweep up and shovel into proper waste container; avoid dry sweeping to minimize dust generation; wash residue with plenty of water
Handling: Avoid contact with skin, eyes, and clothing; minimize dust generation and accumulation; work in well-ventilated space and wash hands before breaks
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated place away from incompatible substances (oxidizers, strong acids or bases); keep away from moisture to prevent degradation
Technical Measures: Store at ambient temperature; provide secondary containment for larger volumes
Control Parameters: No specific occupational exposure limits established
Engineering Controls: Use local exhaust ventilation to keep airborne concentrations low; safety shower and eyewash stations should be available
Personal Protective Equipment: Safety glasses with side shields or goggles, chemically resistant gloves, protective clothing, NIOSH-approved respirator in case of dust formation
