Advice for Firefighters: Keep containers cool by spraying with water, avoid inhalation of vapors, evacuate downwind areas
Hazardous Combustion Products: Emits sulfur oxides, nitrogen oxides, hydrogen fluoride, carbon oxides under fire conditions
Personal Precautions: Wear protective gloves, goggles, and clothing, ensure adequate ventilation, remove sources of ignition
Spill Cleanup: Absorb liquid with inert materials (sand, diatomite), collect residue in chemical waste containers
Environmental Precautions: Prevent from entering drains, watercourses, or soil, notify relevant authorities if significant contamination occurs
Decontamination: Wash area with soap solution, ventilate space, dispose as hazardous chemical waste
Emergency Procedures: Evacuate unnecessary personnel, use proper containment
Handling: Work in fume hood, avoid breathing vapors or mists, use suitable PPE, keep container tightly closed, clean spills immediately
Hygiene Measures: Wash hands before eating or smoking, change contaminated clothing promptly
Storage: Store in a cool, dry, ventilated area, keep away from acids, oxidizers, and moisture, use original tightly sealed containers
Special Precautions: Prevent buildup of static electricity, guard against leakage
Engineering Controls: Use local exhaust ventilation, fume hoods for laboratory work
Personal Protection: Chemical splash goggles, nitrile gloves, lab coat, avoid skin contact
Respiratory Protection: Use NIOSH-approved respiratory protection where vapors or mists exceed recommended exposure levels
Exposure Limits: No occupational exposure limits established specifically, use good laboratory practices
