First Aid Measures

Inhalation: Move the affected person to fresh air immediately. Seek medical advice if breathing becomes difficult, persistent cough, or other symptoms develop. Provide oxygen if breathing becomes labored. Remove contaminated clothing and loosen tight clothing around the neck and chest.
Skin Contact: Wash thoroughly with soap and plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Seek medical attention for persistent skin irritation, blistering, or burns.
Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if present and easy to do. Seek urgent medical care if pain, redness, or blurred vision develop.
Ingestion: Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Immediate medical attention is recommended.
Most Important Symptoms and Effects: Burning sensation, headache, dizziness, coughing, redness, and swelling of exposed areas. Prolonged exposure or ingestion could induce gastrointestinal distress or respiratory symptoms.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam, sand
Unsuitable Media: Do not use water jet directly on chemical as it may spread fire
Specific Hazards: Vapors can form explosive mixture with air and may travel to ignition sources. Decomposition products include hydrogen bromide, carbon oxides, and irritating fumes.
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Additional Advice: Use water spray to cool containers exposed to heat. Contain run-off to prevent entry into water systems, use chemicals in fire area that can neutralize fumes.

Accidental Release Measures

Personal Precautions: Evacuate personnel from area. Wear suitable respirator, chemical-resistant gloves, and protective clothing. Avoid breathing vapors. Ventilate affected area.
Environmental Precautions: Prevent chemical from entering drains, waterways, or soil. Notify environmental and emergency authorities if significant quantities are released.
Clean-Up Methods: Absorb liquid material with inert, non-combustible absorbent (such as sand, earth, or vermiculite). Place spill residue in appropriate waste container and tightly seal. Use tools and equipment that do not generate sparks.

Handling and Storage

Handling Practices: Use only in well-ventilated areas, wear suitable personal protective equipment including gloves and goggles. Keep away from open flames, sparks, and sources of static electricity. Do not inhale vapors; prevent skin and eye contact.
Storage Requirements: Keep containers tightly closed in a cool, dry, well-ventilated space. Store away from incompatible substances such as strong oxidizing agents, strong bases. Store at ambient temperature, away from direct sunlight and sources of ignition.
Technical Measures: Ground and bond containers and transfer equipment. Use explosion-proof equipment where possible. Maintain clear labels and material identification.

Exposure Controls and Personal Protection

Exposure Limits: No specific regulatory limits established; minimize exposures as much as possible
Engineering Controls: Local exhaust ventilation, chemical fume hood, explosion-proof ventilation systems
Personal Protective Equipment: Nitrile or neoprene gloves, splash-proof chemical goggles, laboratory coat or chemical resistant coveralls, appropriate respiratory protection if exposure may exceed limits
Hygiene Measures: Remove and wash contaminated clothing before reuse. Do not eat, drink, or smoke during use. Wash hands thoroughly after handling.
