Immediate Medical Attention: Available eyewash and safety shower recommended in all work areas using this chemical

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray (avoid direct water jet)
Unsuitable Extinguishing Media: Direct water stream can spread product
Hazardous Combustion Products: Hydrogen bromide, bromine fumes, carbon monoxide, carbon dioxide
Special Protective Equipment: Wear full firefighting turn-out gear including self-contained breathing apparatus (SCBA)
Precautions for Firefighters: Move containers away from fire if possible without risk. Keep cool with water spray. Avoid breathing smoke or vapors.
Explosion Risk: Not considered explosive, but releases toxic gases upon burning

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear protective gloves, chemical splash goggles, and suitable clothing
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid discharge to drains, water courses, or soil
Containment and Clean-up: Soak up with inert absorbent (earth, sand, vermiculite). Shovel up into suitable containers for disposal. Wash spill area with detergent and water, avoid using solvents.
Decontamination: Use ample water and household detergent for final cleaning
Disposal: Dispose of recovered material and contaminated absorbents as chemical waste

Handling and Storage

Handling: Use only in well-ventilated areas. Avoid breathing vapors, mist or dust. Avoid contact with skin, eyes and clothing. Keep containers tightly closed. Do not eat, drink or smoke while using.
Storage Conditions: Store in cool, dry, well-ventilated area away from direct sunlight, sources of ignition, oxidizers, acids, and bases. Keep container tightly sealed.
Material Compatibility: Incompatible with strong oxidizing agents.
Special Requirements: Use corrosion-resistant storage containers or linings.
