Inhalation: Move to fresh air, monitor respiration, seek medical help for symptoms like dizziness, headache, or nausea
Skin Contact: Remove contaminated clothing, wash skin with soap and water, get treatment if irritation persists
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses, consult a physician
Ingestion: Do not induce vomiting, rinse mouth, get medical attention immediately, provide water if victim is conscious
Special Notes: Rescue personnel should protect themselves from exposure before attending to the victim, provide suitable personal protective equipment
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (cooling only, avoid stream directly on burning liquid)
Unsuitable Extinguishing Media: Direct streams of water may spread the fire
Special Hazards: Vapors can form explosive mixtures with air, containers may rupture when heated
Protective Equipment: Chemical-resistant suit, self-contained breathing apparatus
Fire/Explosion Risk: Vapors travel to ignition source and flash back
Additional Advice: Keep containers cool by spraying with water, evacuate area, notify nearby personnel, avoid inhaling combustion products
Personal Precautions: Evacuate non-essential personnel, ventilate area, use personal protective gear including gloves, goggles, organic vapor respirator
Environmental Precautions: Prevent entry into drains, surface water and soil, notify authorities in case of significant release
Methods for Clean-Up: Absorb with sand, inert material, collect in suitable container for disposal, ventilate area thoroughly
Decontamination: Wash spill site with plenty of water after material pick-up is complete
Waste Disposal: Handle spilled material as hazardous waste, dispose per local, regional, and national regulations
Safe Handling: Use only in ventilated areas, avoid sparks and open flames, ground and bond containers when transferring liquid, avoid prolonged skin contact
Storage Requirements: Store in strong, tightly closed containers made of stainless steel or compatible plastics, away from heat, ignition sources, and incompatible substances such as oxidizers or acids
Temperature Control: Store under 25°C whenever possible, avoid direct sunlight and static electricity build-up
Other Precautions: Provide safety showers and eyewash facilities where product is handled, do not smoke in storage or handling area
Control Parameters: No specific OSHA or ACGIH limits set, workplace engineering controls such as local exhaust or fume hoods reduce airborne concentrations
Engineering Controls: Use explosion-proof ventilation systems and local exhaust
Personal Protective Equipment (PPE): Nitrile gloves, safety goggles or face shield, flame-resistant lab coats or coveralls, organic vapor respirator if ventilation is inadequate
Hygiene Measures: Wash thoroughly after handling, do not eat, drink, or smoke while using, remove contaminated clothing
