Specific Hazards: Emits toxic fumes of oxides of nitrogen, sulfur, and carbon under fire conditions
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear
Explosion Data: Material does not show explosive properties as supplied, dust accumulation might present risk if dispersed in air and ignited
Firefighting Procedures: Contain run-off to prevent environmental contamination, stay upwind
Personal Precautions: Wear appropriate PPE, avoid contact with skin, eyes, and avoid dust inhalation
Spill Response: Ventilate area, avoid dust formation, sweep up and place material in a suitable container for disposal
Cleaning Methods: Use non-sparking tools, wash area with soap and water after removal
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge into drains, surface and ground waters
Safe Handling: Handle in well-ventilated area, minimize dust, wear protective gloves, clothing, and eye protection, avoid contact or inhalation
Storage Conditions: Store tightly closed in a cool, dry and well-ventilated place, keep away from incompatible substances such as oxidizing agents
Incompatible Materials: Strong oxidizers, acids, bases, sources of ignition, store in chemically resistant container
Occupational Exposure Limits: No established ACGIH or OSHA limits, handle as nuisance dust (total dust: 10 mg/m³)
Engineering Controls: Local exhaust ventilation recommended to keep dust below recommended exposure
Personal Protective Equipment: Splash-proof goggles, chemical-resistant gloves (nitrile or neoprene), long-sleeved clothing, approved dust respirator if ventilation inadequate
