Hazardous Combustion Products: Toxic gases such as sulfur oxides, nitrogen oxides, carbon monoxide, carbon dioxide
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Specific Hazards: Dust may form explosive mixture with air, heating may cause hazardous decomposition
Advice for Firefighters: Cool exposed containers with water spray to prevent pressure build-up, evacuate area promptly if significant fire threatens storage vessel integrity
Personal Precautions: Use protective gloves, goggles, dust mask or respirator as necessary, prevent further leakage or spillage if safe
Environmental Precautions: Do not let material enter storm drains, sewers, or water sources, prevent product from spreading
Methods for Containment: Sweep up or vacuum spilled product using non-sparking tools, transfer into compatible container for disposal
Cleaning Up: Wash spill area thoroughly with water after material removal, ventilate affected area to disperse vapors or dust
Notification: Inform responsible authorities if significant spill reaches environment or water sources
Safe Handling Advice: Avoid contact with skin, eyes and clothing, prevent inhalation of dust, minimize exposure by working in well-ventilated conditions, handle away from heat, sparks, open flames
Storage Conditions: Store locked up in cool, dry, well-ventilated space, use sealed container capable of withstanding potential pressure change, keep separate from strong oxidizers, acids, and bases
