Inhalation: Move affected person to fresh air, keep at rest in a position comfortable for breathing, consult doctor if symptoms persist
Skin Contact: Take off contaminated clothing, rinse skin with water for at least 15 minutes, call a physician if irritation develops or persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical attention if irritation persists
Ingestion: Rinse mouth with water, do not induce vomiting, get medical help right away, never give anything by mouth to an unconscious person
Most Important Symptoms: Redness, itching, pain at contact site, watering eyes, delayed symptoms possible with prolonged exposure
Suitable Extinguishing Media: Dry chemical powder, CO2, alcohol-resistant foam; water spray for larger fires
Unsuitable Extinguishing Media: Avoid using water jets as they may spread the fire
Specific Hazards: During fire, may emit toxic fumes of hydrogen bromide, nitrogen oxides, and carbon oxides
Protective Equipment for Firefighters: Wear full protective gear, use self-contained breathing apparatus, keep containers cool with water spray to avoid pressure build-up
Advice for Firefighters: Move containers from fire area if safe to do so, avoid breathing fumes, control run-off to prevent water contamination
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid dust formation, wear proper protective equipment including gloves, safety goggles, and suitable respiratory protection
Environmental Precautions: Prevent further leakage or spill if safe, do not contaminate water sources, avoid release to soil and drains
Methods for Containment: Scoop up material with suitable non-sparking tools, place into a labeled container for disposal; use absorbent material for any residues
Cleanup Procedures: Clean area thoroughly with water and detergent after material pick-up is complete, dispose of cleaning materials as hazardous waste
Reporting: Notify local authorities in accordance with regulations if large spills have occurred
Precautions for Safe Handling: Use only in well-ventilated locations, avoid inhaling dust or contact with skin and eyes, wash hands and face after handling, do not eat or drink while using
Safe Storage Conditions: Store in tightly closed container in a cool, dry and well-ventilated place, keep away from incompatible materials such as strong oxidizers or acids, keep away from direct sunlight
Incompatible Materials: Avoid contact with strong acids, bases, and oxidizing agents •
Storage Class: Keep in storage area for toxic and hazardous materials, ensure access to eye wash stations and safety showers
Occupational Exposure Limits: No established limits for this substance; minimize workplace exposure through good ventilation and engineering controls
Engineering Controls: Use local exhaust or general room ventilation to maintain airborne levels below recommended exposure limits
Personal Protective Equipment (PPE): Wear chemical-resistant gloves (nitrile or butyl rubber), tightly fitting safety goggles, lab coat, and, where dust may generate, particulate respirator (N95 or better)
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling; remove contaminated clothing and protective equipment before entering eating areas
Environmental Exposure Controls: Prevent materials from release into environment, use spill containment measures, properly label and dispose chemical waste
