Suitable Extinguishing Media: Alcohol-resistant foam, dry powder, carbon dioxide (CO₂), water spray
Fire Hazards: Can release irritating vapors and carbon oxides on combustion
Protective Equipment: Chemical resistant clothing and self-contained breathing apparatus for fire fighters
Firefighting Procedures: Evacuate downwind personnel; use water spray to cool containers exposed to flames; prevent run-off to water systems
Special Hazards: Closed containers may rupture from pressure if heavily heated
Personal Precautions: Use protective gloves, safety glasses, and if needed respiratory protection; remove ignition sources; provide adequate ventilation
Environmental Precautions: Prevent from entering drains, surface water or soil; contain spill with sand or absorbent material
Cleanup Methods: Collect liquid with absorbent material such as sand, diatomaceous earth, or commercial spills kit; sweep up and transfer to properly labeled waste containers; wash relieved area with water and detergent
Reference to Other Sections: See sections on handling, storage and disposal for further information on safe practices
Handling: Wear suitable protective clothing, avoid breathing spray or mist, minimize direct skin contact and wash hands after use; do not smoke or use open flames in handling areas
Storage Conditions: Store in tightly closed original container, in a cool, dry, well-ventilated area away from direct sunlight and sources of heat; maintain temperature below 40°C (104°F) for product stability

Other Advice: Label containers clearly and keep away from foodstuffs or animal feed
Occupational Exposure Limits: No exposure limits established by OSHA, ACGIH or similar agencies
Engineering Controls: Provide adequate ventilation, preferably local exhaust at handling areas
Eye Protection: Wear safety goggles or face shield
Skin Protection: Use chemical-resistant gloves and protective clothing
Respiratory Protection: Not needed for typical ambient use; for high aerosol or vapor concentrations, use NIOSH-approved respirators
Hygiene Measures: Wash hands thoroughly after working with product; avoid eating, drinking, or smoking in work areas
