Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective suit
Firefighting Instructions: Move containers from area if it can be done safely; cool containers with water spray from a safe distance
Unusual Fire Hazards: Decomposition can generate toxic or flammable vapors; minimize exposure and prevent runoff from entering sewers

Accidental Release Measures

Personal Precautions: Evacuate area; ventilate space; avoid dust or vapor formation; prevent contact with skin or eyes
Protective Equipment: Suitable gloves, goggles or full-face shield, lab coat or chemical apron
Emergency Procedures: Stop leak if safe; prevent further leakage or spillage; keep away from drains and water bodies
Clean-Up Methods: Absorb with inert material (sand, diatomite); sweep up and place in proper waste container; wash spill area thoroughly
Environmental Precautions: Prevent product from entering soil, waterways, or storm drains to minimize environmental exposure

Handling and Storage

Safe Handling: Handle in well-ventilated area; minimize dust and aerosol generation; avoid contact with eyes, skin, and clothing
Safe Storage: Keep container tightly closed; store in cool, dry, and well-ventilated space away from incompatible substances (oxidizing agents, strong acids, bases)
Storage Precautions: Protect from direct sunlight and sources of ignition; maintain temperature between 2-25°C; avoid moisture exposure
Incompatible Materials: Avoid strong oxidizers, acids, acid chlorides, acid anhydrides, reducing agents
Special Requirements: Store in properly labeled containers; do not reuse empty containers for other chemicals

Exposure Controls and Personal Protection

Control Parameters: No regulatory occupational exposure limits currently established for this compound; general workplace dust limits may apply
Engineering Controls: Use with local exhaust ventilation or chemical fume hood; implement eyewash and emergency shower in work area
Individual Protection: Chemical-resistant gloves (nitrile, neoprene recommended), protective eyewear (safety goggles), laboratory coat or chemical apron, respiratory protection in absence of adequate ventilation
