Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray
Fire Hazards: Powder can form explosive mixtures with air, hazardous fumes (carbon oxides, nitrogen oxides) possible
Protective Equipment: Wear full fire-fighting turnout gear and self-contained breathing apparatus
Special Procedures: Use water spray to cool unopened containers, prevent runoff from reaching drains or waterways
Personal Precautions: Wear gloves, goggles, avoid dust, ventilate area
Environmental Precautions: Prevent large amounts getting into soil, drains, waterways
Containment and Cleaning: Sweep up material carefully, avoid raising dust, collect in labeled containers, ventilate and wash spill site after pickup
Handling: Work in properly ventilated area, keep container tightly closed, avoid creating dust
Storage: Store in original sealed container in a dry, cool place, away from incompatible materials like strong acids and oxidizers, keep away from food and drink
Engineering Controls: Use lab ventilation (fume hood), regular air changes
Personal Protective Equipment: Safety goggles or glasses, nitrile gloves, standard laboratory coat, in case of dust or mist formation use NIOSH-approved respirator
