Impurities: Typically contains trace amounts of related brominated hydrocarbons
Inhalation: Move individual to fresh air immediately, provide supportive breathing assistance, medical attention in case symptoms persist
Skin Contact: Remove contaminated clothing, flush skin with running water for at least 15 minutes, wash thoroughly with mild soap, seek medical advice if irritation remains
Eye Contact: Rinse eyes with copious amounts of water, occasionally lifting eyelids to ensure thorough irrigation, continue for at least 15 minutes, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, immediately call physician or poison center
Symptoms of Exposure: Burning sensations, coughing, dizziness, nausea, vomiting, possible drowsiness
Notes for Physicians: Treatment should focus on relieving symptoms; monitor for respiratory complications
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, sand, avoid water jets
Fire Hazards: Releases toxic fumes of hydrogen bromide, carbon monoxide, and carbon dioxide during combustion
Firefighting Instructions: Evacuate area, approach fire from upwind, use self-contained breathing apparatus with full protective gear, cool containers exposed to flames
Explosion Hazards: Vapors may travel considerable distance to ignition source; closed containers may rupture
Special Precautions: Remove all sources of ignition, prevent runoff from entering drains or water sources
Personal Precautions: Wear full protective gear including gloves, goggles, respirator if airborne concentrations rise
Environmental Precautions: Prevent chemical from entering drains, surface waterways, or soil
Clean-Up Methods: Ventilate area, absorb spill with inert material (sand, earth), place in tightly sealed labelled containers for disposal; decontaminate area with soap and abundant water
Emergency Procedures: Restrict access to area until clean-up is complete, supervise all personnel involved
Reporting Requirements: Notify local environmental authorities if major spill occurs, as per local laws
Handling: Work in well-ventilated locations, minimize direct contact with skin, always avoid inhalation of vapor; use explosion-proof equipment, ground all containers and transfer lines
Storage: Store in tightly closed containers, away from direct sunlight, sources of heat, spark, or flame; segregate from incompatible substances such as strong oxidizers and strong acids; store in a cool, dry, well-ventilated area
Transfer Recommendations: Use proper grounding and bonding to control static discharge during transfer
Hygiene Measures: Wash hands and exposed skin thoroughly after handling, do not eat, drink, or smoke during use
Occupational Exposure Limit: No specific OSHA PEL, ACGIH TLV; keep exposures as low as achievable
Engineering Controls: Use extraction hoods, local exhaust, chemical-resistant work surfaces, ensure venting to reduce vapor levels
Eye Protection: Safety goggles or face shields
Skin Protection: Impermeable gloves, laboratory coat or chemical-resistant apron
Respiratory Protection: NIOSH approved respirator in cases where vapor concentration may exceed safe limits
Additional Precautions: Eye wash stations and emergency showers should be accessible in work area; proper training in chemical safety required
