Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Specific Hazards: Releases toxic fumes of hydrogen bromide and carbon oxides on burning
Protective Equipment: Self-contained breathing apparatus, full protective gear
Advice for Firefighters: Contain run-off, cool exposed containers with water, watch for flashback
Personal Precautions: Evacuate unnecessary personnel, avoid inhalation or contact, ventilate area
Protective Equipment: NIOSH-approved respirator, chemical-resistant gloves, splash goggles, protective clothing
Environmental Precautions: Prevent spillage entering drains, watercourses, or soil
Cleanup Methods: Absorb spill with inert material, place in suitable chemical waste container, decontaminate the area with detergent and water, dispose as hazardous waste
Safe Handling: Work in well-ventilated areas or fume hoods, avoid contact with skin or eyes, avoid inhalation of vapors or powder, wash after use
Storage Conditions: Store in cool, dry, well-ventilated location, keep container tightly closed, separate from incompatible materials such as strong bases, oxidizers, and reducing agents, protect from moisture and light
Specific Uses: Restrict to trained personnel, use for designated applications only
Exposure Limits: No established OSHA or ACGIH TLV for tetrabromomethane, minimize exposure as a precaution
Engineering Controls: Use process enclosures, fume hoods, or adequate ventilation systems
Personal Protection: Safety goggles, chemical-resistant gloves (nitrile or neoprene), laboratory coat or coveralls, NIOSH-approved respirator for higher exposure, emergency eye wash and shower accessible
