Inhalation: Move affected person to fresh air quickly; if breathing difficulties arise, provide oxygen, seek immediate medical help
Ingestion: Do not induce vomiting; rinse mouth, drink 1–2 glasses of water if conscious, call poison control or physician right away
Skin Contact: Remove contaminated clothing immediately, rinse skin thoroughly with soap and water for at least 15 minutes; medical attention required if irritation persists
Eye Contact: Flush eyes immediately with plenty of water for at least 15 minutes, hold eyelids open, remove contact lenses, seek prompt medical care
Symptoms of Exposure: Drowsiness, headache, lethargy, irritation, nausea, weakness; more severe cases show organ effects
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder, water spray
Fire Hazards: Vapors form explosive mixtures with air, containers may rupture from excess heat, emits toxic gases such as carbon monoxide and carbon dioxide when burning
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear to avoid inhaling fumes or skin contact
Special Procedures: Cool exposed containers with water spray, prevent runoff from entering drains or water courses; avoid static discharge
Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear impervious gloves, chemical goggles, protective clothing
Environmental Precautions: Prevent material from entering sewers, surface water, or soil; use barriers as needed
Containment Methods: Absorb with inert material such as sand or clay; scoop into labeled containers for disposal
Cleaning Methods: Wash spill area with water and detergent, ventilate thoroughly; dispose of waste according to local regulations
Handling Procedures: Use only in well-ventilated areas; keep away from sparks, heat, open flames; avoid contact with eyes, skin, clothing; wash after use; keep container tightly closed when not in use
Storage Requirements: Store in cool, dry, well-ventilated area away from oxidizers, acids, and ignition sources; keep containers tightly sealed; use proper grounding and bonding during liquid transfer
Incompatibilities: Strong oxidizing agents, strong acids, alkali metals; may attack some plastics and rubbers
Permissible Exposure Limits: OSHA TWA: 5 ppm; ACGIH TWA: 5 ppm, STEL: 10 ppm
