Inhalation: Move to fresh air, seek medical attention if symptoms develop, provide artificial respiration if not breathing Skin Contact: Remove contaminated clothing, wash with soap and plenty of water for at least 15 minutes, seek medical advice if irritation persists Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, consult physician Ingestion: Do not induce vomiting, rinse mouth, give water if conscious, get medical attention
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder Unsuitable Media: Direct water jet may spread the fire Special Hazards: Gives off toxic fumes (nitrogen oxides, carbon monoxide) during combustion Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear Advice for Firefighters: Move containers from fire area if possible, cool containers with water spray from safe distance
Personal Precautions: Evacuate area, use personal protective equipment, avoid breathing vapors Environmental Precautions: Prevent entry into drains, waterways, and soil Methods for Cleanup: Absorb with inert material (sand, earth), place in chemical waste container, wash area with detergent and water Notification Procedures: Inform authorities as required by local regulation
Handling: Avoid contact with skin and eyes, maintain good ventilation, ground and bond containers during transfer, keep away from heat, sparks, and open flame Storage: Store in tightly closed container, cool, dry, well-ventilated area, protect from moisture, keep away from strong oxidizing agents, acids, and foodstuffs Incompatibilities: Strong acids, oxidizers, peroxides
Engineering Controls: Use fume hood or local exhaust ventilation, maintain eyewash stations and safety showers Respiratory Protection: NIOSH-approved respirator when ventilation is inadequate Eye Protection: Chemical safety goggles and face shield Hand Protection: Nitrile or neoprene gloves Skin Protection: Chemical-resistant apron and boots Occupational Exposure Limits: No specific OSHA or ACGIH limits, minimize exposure as a chemical irritant Environmental Controls: Prevent discharge into environment
