Suitable Extinguishing Media: Use carbon dioxide, dry chemical, or foam for small fires, water spray for larger fires but avoid directed stream if liquid fire risk
Unsuitable Extinguishing Media: Avoid high-pressure water jets, may spread product
Specific Hazards Arising: Emits toxic fumes of nitrogen oxides, hydrogen fluoride, sulfur oxides, carbon monoxide when exposed to fire
Protective Equipment and Precautions: Firefighters require full protective clothing and self-contained breathing apparatus, keep containers cool by spraying with water if exposed to heat or fire, prevent runoff from entering drains or natural waterways
Personal Precautions: Evacuate unnecessary personnel, wear respirator, chemical goggles, protective gloves, and impermeable clothing
Environmental Precautions: Avoid discharge into sewers, ground, or environmental water systems; collect discharge and waste for appropriate disposal
Containment and Cleanup: Ventilate area; contain spilled material using inert absorbent (sand or vermiculite); gather residue using non-sparking tools, transfer to sealed, labeled containers; clean area with detergent and water; dispose of waste in compliance with local regulations
Handling: Minimize generation of dust or aerosols; use only in well-ventilated settings; avoid breathing vapors, dust, or mist; keep container tightly sealed when not in use; handle using appropriate personal protective equipment; keep away from food, beverages, and feed products
Storage: Store in cool, dry, and well-ventilated place; keep original container tightly closed; store away from incompatible substances such as strong oxidizers, acids, and bases; avoid heat, sparks, and flame; keep container upright to prevent leaks or accidental exposure; use secondary containment if required by workplace safety practices
Occupational Exposure Limits: No established exposure limits for this compound; general threshold limit values for nuisance dusts may apply
Engineering Controls: Provide local exhaust ventilation at sources of dust or vapor; use process enclosures and mechanical controls where possible
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, laboratory coat or apron, respiratory protection for dust or vapor depending on site conditions, eyewash facilities and safety showers should be accessible nearby
Hygiene Measures: Hand washing after handling; avoid contact with skin, eyes, clothing; avoid eating, drinking, or smoking in work area; regularly clean personal clothing and protective equipment

Decomposition Products: Thermal decomposition releases toxic gases (hydrogen fluoride, nitrogen oxides, sulfur oxides, carbon oxides, fluorinated organic compounds)
Hazardous Polymerization: Will not occur under normal processing
Acute Toxicity: No official LD50 values available for humans; data from analogs indicate low to moderate oral toxicity in rodents; may cause drowsiness, muscle weakness or mild headaches
