Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical dust, CO2, alcohol-resistant foam, water fog
Unsuitable Extinguishing Media: Do not use direct water jet
Hazardous Combustion Products: Toxic fumes including nitrogen oxides, carbon monoxide, carbon dioxide
Special Hazards: Vapors heavier than air, risk of dust explosion in air, containers may rupture from pressure
Protective Equipment: Full turn-out gear, self-contained breathing apparatus
Precautionary Statements: Stay upwind, cool containers exposed to flames, keep fire area isolated

Accidental Release Measures

Personal Precautions: Ventilate spill area well, avoid dust, prevent skin or eye contact, wear gloves and goggles
Environmental Precautions: Prevent chemical entering drains, soil, watercourses
Containment and Clean-Up: Sweep or scoop solid spills, place in suitable labelled waste containers, wipe leftover with damp cloth, use non-sparking tools
Disposal: Dispose according to local, national, environmental laws for organic chemicals

Handling and Storage

Safe Handling: Handle in fume hood or well-ventilated spot, avoid dust generation, keep away from open flames, avoid eating or drinking around material
Storage Conditions: Keep sealed in original labelled container, store in dry, cool area, away from heat sources, separate from oxidizing agents
Incompatibilities: Strong acids, oxidizers like peroxides
Hygiene Measures: Wash hands thoroughly before eating or leaving work, remove contaminated clothing

Exposure Controls and Personal Protection

Engineering Controls: Work in local exhaust ventilation or approved fume hood, avoid breathing dust
Personal Protective Equipment: Protective lab coat, chemical-resistant gloves (nitrile or similar), safety goggles
Respiratory Protection: Dust mask or half-face respirator for airborne exposure, especially during weighing or transfer
Hand Protection: Use gloves designed for chemical splash
Eye Protection: Tight-seal safety eyewear
Skin Protection: Full-length sleeves, coverage for feet, avoid shorts and sandals
