Inhalation: Move victim to fresh air. Keep at rest in a position comfortable for breathing. Seek medical attention for symptoms like cough or shortness of breath.
Skin Contact: Remove contaminated clothing. Wash skin with soap and water. Seek medical advice if irritation persists.
Eye Contact: Rinse eyes cautiously with water for several minutes. Remove contact lenses if present and easy. Continue rinsing. Obtain medical attention if irritation does not subside.
Ingestion: Rinse mouth. Do not induce vomiting. Call a poison center or physician.
Indication of Immediate Medical Attention: Allergic reaction symptoms, persistent irritation, or breathing difficulties call for prompt evaluation.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet (scattering hazard)
Specific Hazards: Under fire, may produce toxic fumes including nitrous gases, hydrogen chloride, hydrogen fluoride
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing.
Special Precautions: Cool exposed containers with water spray to prevent pressure build-up; prevent runoff from entering drains or water bodies.
Hazardous Decomposition Products: Fumes of hydrochloric acid, hydrofluoric acid, nitrogen oxides, carbon oxides
Personal Precautions: Wear chemical-resistant gloves, protective eyewear, and dust mask.
Environmental Precautions: Stop material from entering sewers, storm drains, waterways or soil.
Methods for Clean-Up: For dry material, sweep up and place in a properly labeled container for disposal. For spilled solution, absorb with earth, sand, or inert material. Ensure proper disposal following local, regional, and national guidelines.
Decontamination: Wash spill area thoroughly with water and detergent.
Disposal: Prevent contamination of water sources. Dispose of material and contaminated cleanup supplies following regulations.
Safe Handling: Avoid formation of dust or aerosol. Use in well-ventilated area. Avoid contact with skin, eyes, and clothing. Keep containers tightly closed when not in use.
Personal Hygiene: Wash hands and exposed skin before breaks and after handling. Remove contaminated clothing and wash before reuse.
Storage Conditions: Store in original labeled container, in cool, dry, well-ventilated area away from heat sources, direct sunlight, food, feed, and incompatible materials. Keep containers secure against physical damage and sealed when not in use.
Incompatible Substances: Strong oxidizers, acids, bases
Packaging Materials: Use containers that prevent moisture ingress and chemical absorption by container walls.
Engineering Controls: Use local exhaust ventilation or process enclosure if dust or aerosol generation is possible.
Respiratory Protection: Approved dust mask or respirator may be needed for high-dust operations.
Skin Protection: Chemical-resistant gloves (nitrile or neoprene). Wear long-sleeved shirts, long pants, chemical-resistant apron if exposure likely.
Eye Protection: Chemical safety goggles or faceshield.
Environmental Controls: Do not allow product to contaminate water sources. Observe established emission standards.
