Inhalation: Move affected person to fresh air immediately. Seek medical attention if respiratory symptoms persist. Remove any contaminated clothing.
Skin Contact: Flush contaminated skin with plenty of water for at least 15 minutes. Remove contaminated clothing. Get medical help if irritation develops or persists.
Eye Contact: Rinse eyes cautiously with water for several minutes. Hold eyelids apart and continue rinsing. Seek emergency medical attention if irritation occurs.
Ingestion: Rinse mouth with water. Give water if the person is conscious and alert. Do not induce vomiting. Get medical attention right away.
Notes for Medical Providers: Provide symptomatic and supportive treatment. Monitor for signs of irritation or other acute symptoms.
Suitable Extinguishing Media: Use dry chemical, CO2, water spray, or foam. Use media appropriate for surrounding fire.
Specific Hazards: Combustion releases toxic fumes including hydrogen fluoride, nitrogen oxides, sulfur oxides, and carbon oxides.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear to avoid inhalation of smoke or exposure to residues.
Special Procedures: Cool containers with water if exposed to heat. Prevent runoff from fire control from entering drains or water bodies.
Fire/Explosion Risk: Product itself is considered stable under normal conditions but may decompose at elevated temperature.
Personal Precautions: Evacuate area. Avoid breathing vapors, mist, or dust. Wear protective equipment including gloves and eye protection.
Environmental Precautions: Prevent release to drains, surface water, soil, or sewers. Alert environmental authorities if spill occurs.
Cleanup Methods: Absorb liquid with inert, non-combustible material (sand, earth, diatomaceous earth). Place in suitable chemical waste container. Wash contaminated area with water, avoid splashing.
Containment: If safe, stop leak at source. Use dikes or barriers to contain spill.
Disposal: Dispose of waste and contaminated material through an approved chemical waste contractor. Label waste appropriately.
Handling: Handle in a well-ventilated area. Avoid contact with eyes, skin, and clothing. Avoid inhalation of vapors or spray. Keep away from food and beverages.
Storage Conditions: Store tightly closed in original container. Maintain at room temperature in a dry, well-ventilated location. Keep away from heat sources, sparks, and open flame.
Incompatible Materials: Oxidizing agents, strong acids and bases. Do not store with food products or animal feed.
Hygiene Measures: Wash hands before eating, drinking, or leaving work. Do not reuse empty containers.
Exposure Limits: No specific exposure limits set for this material.
Engineering Controls: Use chemical fume hood or local exhaust ventilation to minimize airborne concentrations.
Personal Protective Equipment:
- Eyes: Safety goggles or face shield
