Eye Contact: Flush eyes gently with water for at least 15 minutes. Seek medical attention if irritation persists.
Skin Contact: Wash affected area thoroughly with plenty of water and soap. Remove contaminated clothing and seek help for irritation.
Inhalation: Move individual to fresh air, keep person warm and at rest. If breathing difficulty develops, get medical attention.
Ingestion: Rinse mouth with water, do not induce vomiting. Drink water and seek professional medical advice.
Note for Physician: Symptomatic treatment; no specific antidote exists. Monitor for signs of bromism with chronic exposure.
Suitable Extinguishing Media: Use water spray, foam, dry powder, or carbon dioxide suitable for surrounding fire
Specific Hazards: Potassium Bromide does not burn or support combustion; toxic fumes may form if mixed with strong acids and exposed to heat
Special Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus for major fires
Explosion Risk: No known explosion hazard with normal handling.
Personal Precautions: Wear proper protection including gloves, goggles, and dust mask. Avoid generating dust.
Environmental Precautions: Prevent entry to waterways and drains. Contain large spills with barriers or absorbent materials.
Cleanup Methods: Sweep or vacuum non-dispersively. Transfer to proper containers for disposal. Wash spill area with water after material pickup.
Reference to Other Sections: Refer to Exposure Controls and Personal Protection for guidance.
Handling: Handle in well-ventilated areas. Minimize dust generation. Use appropriate precautions to avoid skin or eye contact.
Storage: Store in a dry, cool, well-ventilated place away from incompatible substances such as acids
Packing Materials: Keep in tightly closed containers made of suitable materials such as polyethylene or glass
Safe Storage Level: Avoid storing above 25°C, keep away from direct sunlight, moisture and foodstuffs.
Occupational Exposure Limits: No specific limits established for Potassium Bromide, but avoid inhaling dust
