Skin Contact: Remove contaminated clothing, rinse skin with plenty of water. Seek medical attention if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes, lifting upper and lower eyelids. Get immediate medical attention if irritation persists.
Inhalation: Move person to fresh air, keep comfortable for breathing. Consult a medical professional if symptoms such as coughing or shortness of breath occur.
Ingestion: Rinse mouth. Do not induce vomiting. Give water if conscious. Get medical attention without delay.
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam.
Specific Hazards: Product itself does not burn. Decomposition can release bromine vapors and hydrogen bromide gases.
Special Protective Equipment: Firefighters should use self-contained breathing apparatus and wear full protective gear.
Additional Information: Prevent run-off from contaminating water sources or sewers.
Personal Precautions: Wear chemical-resistant gloves, eye protection, and a dust mask. Avoid breathing dust or vapors.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, water courses, or onto the ground.
Methods for Cleaning Up: Sweep up or shovel into suitable containers. Dispose of in accordance with local regulations. Residue can be wiped up with damp cloths. Wash spill area with plenty of water.
Safe Handling: Use only with adequate ventilation. Minimize dust creation and accumulation. Avoid contact with eyes, skin, or clothing. Do not eat, drink, or smoke around product.
Storage Conditions: Store in tightly closed containers in cool, dry, well-ventilated area. Keep away from incompatible materials such as acids or oxidizing agents. Protect from moisture. Label all containers clearly.
Control Parameters: No occupational exposure limits established for calcium bromide. Use general exhaust ventilation.
Personal Protective Equipment: Wear protective clothing, gloves (nitrile or rubber), chemical splash goggles. In dusty conditions, use NIOSH-approved particulate respirator.
Hygiene Measures: Wash hands thoroughly after handling. Remove and wash contaminated clothing before reuse.
