Inhalation: Move person to fresh air immediately. Keep victim warm and at rest. Seek medical attention if coughing, wheezing, or respiratory discomfort persists
Skin Contact: Remove any contaminated clothing. Rinse affected skin under running water for 15 minutes. Soap can help remove residue. Seek medical help if irritation or pain continues
Eye Contact: Rinse cautiously with water for 15 minutes, keep eyelids open and away from eye. Remove contact lenses if present and easy to do. Continue rinsing and seek specialist advice
Ingestion: Rinse mouth with water. Do not induce vomiting. Give small amounts of water to drink if the person is conscious. Get immediate medical attention. Never give anything by mouth to an unconscious person
Note to Physician: Treat symptomatically, monitor for delayed pulmonary effects. Watch for allergic or systematic response
Suitable Extinguishing Media: Use foam, dry chemical, CO₂, or water spray to extinguish fire
Unsuitable Extinguishing Media: Do not use strong water jet as this may spread material
Hazardous Combustion Products: Hydrogen bromide, nitrogen oxides, carbon oxides, toxic fumes
Protection for Firefighters: Wear full protective firefighting gear with self-contained breathing apparatus. Approach from upwind side

Personal Precautions: Avoid breathing dust or vapors, use appropriate PPE – gloves, goggles, lab coat, and mask
Environmental Precautions: Do not let material enter drains or surface water. Prevent further leakage or spillage
Spill Clean-up Methods: Sweep up spill with minimal dust formation and collect in labeled, sealed container for approved disposal. Use vacuum with HEPA filter only if needed
Decontamination: After removal, wash spill area with soap and water. Ventilate and check for residues by wet wiping
Disposal of Cleanup Materials: Handle as hazardous waste, follow disposal instructions below
Safe Handling: Work in a chemical fume hood or well-ventilated area. Avoid generating dust. Do not eat, drink, or smoke while handling
Personal Protection: Use safety goggles, gloves (nitrile or neoprene), lab apron or coat. Wash thoroughly after use
