Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water jets may spread chemical
Specific Hazards During Fire: Product decomposes under fire releasing toxic fumes such as nitrogen oxides, carbon monoxide, boron oxides, cyanide-related gases
Protective Equipment for Firefighters: Use full protective gear and self-contained breathing apparatus against hazardous vapors and decomposition products
Firefighting Instructions: Isolate affected area, cool containers exposed to flames, use water spray to reduce vapors

Accidental Release Measures

Personal Precautions: Wear gloves, safety goggles, lab coat, prevent inhalation and contact with skin or eyes, ventilate area
Environmental Precautions: Prevent further leakage, avoid discharge to drains, soil, water bodies
Cleanup Methods: Use inert absorbent materials (sand, vermiculite), collect residue in secure containers, wash spill area thoroughly, dispose according to local waste regulations
Notification: Inform authorities if significant leaks contaminate waterways or sewers

Handling and Storage

Handling Precautions: Work in well-ventilated fume hood, avoid dust generation, prevent static discharge, wear appropriate PPE, do not eat, drink or smoke while handling
Storage Conditions: Store in tightly closed container, keep in a dry, cool, and well-ventilated place away from heat, ignition sources, incompatible substances such as strong oxidizers and acids
Handling Advice: Minimize quantities stored, maintain good housekeeping, label all containers clearly, limit unauthorized access

Exposure Controls and Personal Protection

Engineering Controls: Use chemical fume hood, emergency shower and eyewash stations nearby
Respiratory Protection: Use approved respirator if dust or vapors may form
Eye/Face Protection: Goggles or safety glasses with side shields
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), lab coat, close-toed shoes
