Most Likely Symptoms: Burning sensation, redness, pain in exposed areas, coughing, and gastrointestinal discomfort after ingestion
Notes for Practitioners: Supportive treatment and symptomatic care, monitor for damage to respiratory tract or digestive system
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Avoid direct stream of water which can spread materials
Fire Hazard: Not flammable, but corrosive fumes (bromine, zinc oxide) can result from decomposition at high temperatures
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Special Procedures: Move containers from fire if safe; cool with water from a safe distance to prevent rupture; keep out of drains and waterways to minimize runoff
Decomposition Products: Bromine gas, zinc oxide fumes
Personal Protection: Wear chemical-resistant gloves, splash-proof goggles, protective clothing, and approved respiratory protection
Evacuation: Move unprotected personnel to safe area, minimize exposure
Containment: Prevent product from entering drains, sewers, waterways, or soil
Clean-up Methods: Sweep or absorb spilled material with inert absorbents (vermiculite, sand), collect in suitable closed container for disposal; wash area with plenty of water and minimize dust
Environmental Precautions: Notify authorities in event of a large release; avoid contamination of ground and surface water
Disposal of Decontaminated Material: Place in sealed labeled waste drum for regulated disposal
Handling: Avoid contact with skin, eyes, and clothing; avoid breathing dust, mist, or vapors; use in well-ventilated area or with local exhaust; do not eat, drink, or smoke while using
Hygiene: Wash hands and exposed areas before eating, after finishing work, or after accidental contact
Storage Conditions: Store in cool, dry, well-ventilated area away from moisture, incompatible substances (acids, strong oxidizers), and sources of heat
Container Requirements: Use corrosion-resistant containers clearly labeled for zinc bromide; keep tightly closed
Incompatibilities: Avoid storage near aluminum, magnesium, or alkali metals to prevent hazardous reactions and container damage
Storage Life: Stable when sealed and protected from moisture; inspect containers for corrosion regularly
Occupational Exposure Limits: No established OSHA or ACGIH limits for zinc bromide; minimize exposure as a general precaution
Engineering Controls: Use local exhaust and general ventilation to keep airborne levels below irritation threshold
Eye Protection: Chemical safety goggles meeting EN 166 or equivalent
Hand Protection: Impervious gloves (nitrile rubber, neoprene)
Body Protection: Chemical-resistant clothing, lab coat, or apron
Respiratory Protection: NIOSH/MSHA-approved respirator in case of inadequate ventilation or if dust/mist present
