Ingestion: Unlikely route of exposure, do not induce vomiting, seek medical help
Most Important Symptoms/Effects: Shortness of breath, coughing, dizziness, drowsiness, unconsciousness, cancer risk after repeated exposure
Immediate Medical Attention: Provide oxygen if breathing is difficult, perform artificial respiration as needed, get medical aid for all significant exposures
Suitable Extinguishing Media: Use dry chemical, CO2, or alcohol-resistant foam; water spray for cooling exposed containers only
Unsuitable Extinguishing Media: Do not use water jet directly on fire
Specific Hazards Arising: Highly flammable gas, forms explosive mixtures with air, may produce toxic and corrosive gases (HBr, CO)
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Special Procedures: Evacuate area, fight fire from safe distance, stop leak if safe
Explosion Data: Vapors heavier than air, may travel long distances to ignition sources, flashback possible
Personal Precautions: Evacuate personnel, eliminate ignition sources, ventilate area, wear appropriate PPE including respiratory protection
Environmental Precautions: Prevent release into soil, drains, waterways, or sewers; notify authorities
Methods for Cleaning Up: Stop gas flow if it can be done safely, ventilate area, use explosion-proof equipment, do not touch or walk through spilled material
Other Information: Isolate hazard area and keep unauthorized personnel away, monitor oxygen levels in confined spaces
Handling: Use only in explosion-proof fume hoods or approved systems, ground/bond containers and equipment, avoid inhalation, contact with skin and eyes, refrain from smoking near storage or handling areas
Storage: Store in cool, well-ventilated, secure facility, keep away from heat, sparks, open flames and incompatible materials; use pressure-resistant containers with proper labeling
Incompatibilities: Strong oxidizers, peroxides, acids, alkali metals
Other Precautions: Check container integrity regularly, keep containers tightly closed when not in use, install gas detection and alarm systems where stored
Occupational Exposure Limits: ACGIH TLV: 0.1 ppm (TWA); OSHA PEL: 0.1 ppm, confirmed animal carcinogen
Engineering Controls: Provide local exhaust ventilation, ensure explosion-proof electrical equipment, monitor airborne levels regularly
Respiratory Protection: Use supplied air or self-contained breathing apparatus in case of inadequate ventilation or high exposure
Hand Protection: Wear chemical-resistant gloves (butyl rubber or nitrile recommended)
