Inhalation: Move person to fresh air, keep comfortable for breathing, consult physician if symptoms persist, in case of respiratory distress administer oxygen
Skin Contact: Remove contaminated clothing, wash affected area with soap and water for at least 15 minutes, seek medical attention for persistent irritation or blistering
Eye Contact: Rinse cautiously with clean water for 15 minutes, remove contact lenses, continue irrigation, obtain immediate medical attention if redness, pain, or vision disturbance remains
Ingestion: Rinse mouth with water, do not induce vomiting, never give anything by mouth to an unconscious person, immediate medical intervention required, monitor for nausea or abdominal pain
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray for large fires, avoid using straight water streams
Specific Hazards: Thermal decomposition generates toxic fumes of nitrogen oxides, sulfur oxides, and carbon oxides
Protective Equipment: Firefighters wear full protective gear, including self-contained breathing apparatus
Special Procedures: Move containers from fire area if possible without risk, cool fire-exposed containers with water, avoid runoff of firefighting water into sewers or water bodies
Personal Precautions: Wear proper personal protective equipment—gloves, eye protection, respirator for dust or fume exposure—provide adequate ventilation
Environmental Precautions: Prevent entry to sewers, drains, waterways, avoid soil contamination, notify authorities if significant spill enters environment
Spill Cleanup Methods: Ventilate area, contain spill with inert absorbent material (sand, earth, vermiculite), sweep up and transfer to labeled chemical waste containers for proper disposal, clean residual surface with water and detergent, avoid dust generation
Safe Handling: Minimize dust formation, avoid inhalation and direct contact, use with local exhaust ventilation, do not eat, drink, or smoke during use, keep work area clean
Storage Conditions: Store in tightly sealed containers, in a cool, dry, well-ventilated place, keep away from incompatible materials such as oxidizing agents or acids, prevent exposure to direct sunlight or moisture, label containers clearly
Incompatible Materials: Strong oxidizers, strong acids, bases, reducing agents, and halogens
Exposure Limits: No occupational exposure limits specifically established; handle as hazardous substance, follow precautionary standards
Engineering Controls: Provide local ventilation or process enclosure, use eye wash stations and emergency showers, ensure general mechanical ventilation
Personal Protection: Wear appropriate protective gloves (nitrile or neoprene), chemical safety goggles, impervious clothing, suitable respiratory protection for dust or mist above exposure guidelines
Hygiene Measures: Wash hands, arms, face thoroughly after handling and before breaks, launder protective clothing regularly, do not carry contaminated clothing outside the workplace
