Specific Hazards: Emits irritating fumes like nitrogen oxides or phosphorus oxides at high heat
Protective Equipment: Use self-contained breathing apparatus, wear protective clothing
Advice for Firefighters: Avoid inhalation of combustion products, control run-off water to prevent contamination

Accidental Release Measures

Personal Precautions: Wear dust mask, gloves, goggles, prevent dust formation
Environmental Precautions: Prevent large quantities from entering drains, surface waters, soils
Clean-up Methods: Sweep or vacuum up the spilled material, avoid dry sweeping to limit dust, place in sealed containers for disposal
Decontamination: Wash spill area with water after collection, ventilate

Handling and Storage

Handling: Minimize dust, keep containers tightly closed, use only with adequate ventilation, avoid inhalation or skin contact
Storage: Store in dry, cool, and well-ventilated area, away from acids and strong oxidizers, keep out of sunlight and moisture
