Inhalation: Move individual to fresh air immediately, maintain an open airway, seek medical help if breathing becomes difficult or coughing persists
Skin Contact: Wash with copious amounts of water for 20 minutes, remove contaminated clothing, seek medical advice for persistent irritation or burns
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present, obtain medical attention promptly due to risk of permanent eye injury
Ingestion: Rinse mouth thoroughly, drink plenty of water, avoid inducing vomiting, seek immediate emergency medical care due to potential systemic toxicity
General Notes: Provide the product label or SDS to medical personnel, stay with exposed person and monitor symptoms
Suitable Extinguishing Media: Flood fire with water spray, use large volumes of water, avoid dry chemical extinguishers and carbon dioxide which may react violently
Specific Hazards: Product decomposes under intense heat to release toxic gases such as bromine, bromine oxides, and metal fumes, strong oxidizing nature increases intensity of fire, contact with organic materials or combustibles can cause rapid combustion
Protective Equipment: Firefighters use full protective gear including self-contained breathing apparatus (SCBA), chemical-resistant gloves, and fire-resistant clothing
Firefighting Instructions: Approach from upwind, stay clear of downwind plume, cool unaffected containers with water to prevent rupture
Personal Precautions: Evacuate unprotected personnel, restrict area, ventilate space, utilize full face respirator if dust is present, wear chemical-resistant gloves and impervious coveralls
Environmental Precautions: Prevent substance from entering drains, waterways or soil, consult environmental agency in event of large spill, use barriers to contain runoff
Containment Methods: Avoid creating dust, sweep up carefully with non-sparking tools, transfer to clean, dry, clearly labeled containers, avoid mixing with combustibles
Cleanup Methods: Collect and store waste for disposal by licensed hazardous waste handler, decontaminate area with large quantities of water if safe, monitor for persistent contamination
Safe Handling: Manipulate in a well-ventilated area, do not handle near open flame, heat, or sources of ignition, ground equipment to avoid static discharge, handle with dry hands or gloves, never return unused material to the original container
Storage Conditions: Store in cool, dry, well-ventilated room designed for oxidizer storage, keep out of direct sunlight and away from heat, segregate from combustibles, reducing agents, acids, and organic materials, tightly seal container and use corrosion-resistant shelving
Incompatibles: Flammable liquids, organic chemicals, metallic powders, sulfur, phosphorus, strong acids, strong bases
Additional Precautions: Label containers clearly, restrict access to authorized individuals trained in handling oxidizers, maintain an updated inventory
Occupational Exposure Limits: No OSHA or ACGIH TLV for zinc bromate specifically, observe workplace guidelines for respirable dusts and bromate compounds
Engineering Controls: Use local exhaust ventilation, process enclosures, and dust collection systems to minimize airborne particles, maintain eye wash and safety showers nearby
Personal Protective Equipment (PPE): Wear chemical splash goggles, face shield if splashing risk increases, acid/oxidizer-resistant gloves, long-sleeved impervious garments, dust mask (minimum N95) or full-face respirator in inadequate ventilation
Hygiene Measures: Wash hands and face before eating, do not eat, drink, or smoke in work areas, remove and wash contaminated clothing separately
