Important Symptoms: Possible burning, stinging, redness, respiratory discomfort, nausea, abdominal pain
Immediate Medical Attention: Required in cases of extensive exposure, persistent symptoms, ingestion, or inhalation of powder or dust
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, sand for small fires, water spray for larger fires only when compatible with containment practices
Unsuitable Extinguishing Media: Do not use strong water jets
Specific Hazards: Combustion can produce carbon oxides, nitrogen oxides, hydrogen bromide fumes hazardous to health
Special Protective Equipment: Wear self-contained breathing apparatus and full protective suit; approach upwind, avoid inhaling fumes
Fire-Fighting Guidance: Cool containers with water spray, avoid runoff into water systems, contain contaminated firewater for authorized disposal, evacuate personnel from area if required due to toxic fumes
Personal Protection: Evacuate non-essential staff, ventilate area, wear PPE—splash goggles, gloves, lab coat, if airborne risk exists use a respirator
Environmental Precautions: Prevent spills from entering drains, waterways, or soil
Cleanup Procedure: Scoop up material, sweep or vacuum without generating dust, place in suitable sealed containers, wash area thoroughly with water and detergent, dispose of cleaning materials as hazardous waste
Additional Guidance: Avoid direct contact, consult relevant emergency protocols for chemical spills in laboratory or industrial settings, coordinate with local environmental health and safety teams where available
Handling: Keep away from sources of heat, sparks, open flame, strong acids or bases; handle under local exhaust ventilation, minimize dust creation by using wet methods; avoid ingestion, inhalation, or absorption through skin and eyes
Storage: Store in tightly closed original containers in a cool, dry, well-ventilated place, segregated from incompatible materials such as strong oxidizers and reducing agents, acids
Hygiene Measures: Wash hands, forearms, and face after handling, remove contaminated clothing away from eating or drinking areas, do not eat, drink or smoke in work area
Incompatibilities: Exposure to strong oxidizers may cause exothermic or hazardous reactions; avoid moisture ingress to product containers, keep away from sunlight
Exposure Limits: No established occupational exposure limits for this specific compound; avoid exposure to dusts, follow lab safety protocols for chemicals with similar hazard profiles
Engineering Controls: Use fume hood, local exhaust, or mechanical ventilation to keep concentrations below any likely occupational exposure limits
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), lab coat or coveralls, safety goggles with side shields, approved respirator if risk of dust or aerosol exists
Other Precautions: Emergency wash stations and eye rinse stations available where handled, keep chemical inventory updated, ensure proper staff training in safe use
