Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam
Unsuitable Media: Direct water streams can spread chemical
Hazards on Burning: Releases toxic gases such as hydrogen chloride, bromine
Protective Equipment: Firefighters wear self-contained breathing apparatus and protective gear
Special Risks: Vapors heavier than air, collect in low spots, risk of flashback to ignition sources
Personal Precautions: Wear protective gloves, eye protection, respirator
Environmental Precautions: Prevent runoff to drains, avoid contamination of soil and waterways, alert responsible authorities if spill enters environment
Cleanup Methods: Contain with absorbent (vermiculite, sand), scoop into a closed container, ventilate area thoroughly, dispose of according to regional rules
Handling Tips: Work in well-ventilated space, avoid breathing vapors, don’t handle near sources of heat, sparks, or flame
Avoid Contact: Direct contact with eyes, skin, clothes
Storage Requirements: Store below room temperature, in tightly sealed metal or glass container, away from direct sunlight, oxidizing agents, acids, and bases
Special Handling Precautions: Use tools to transfer, ground containers against static, keep away from food and drink areas
Occupational Exposure Limits: No established limit in most regions, but minimal exposure always recommended
Engineering Controls: Fume hood, mechanical exhaust recommended
Personal Protective Equipment: Chemical-resistant gloves, splash goggles, lab coat, closed shoes, NIOSH-approved respirator for high vapor
Hygiene: Wash hands before eating or drinking, don’t smoke in work area, remove contaminated clothing before leaving workzone
