Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide (CO2), water spray (to cool containers)
Unsuitable Extinguishing Media: Strong water jets may spread material
Specific Hazards: Flammable vapors may form explosive mixtures with air, combustion may release toxic gases including carbon oxides, product containers may rupture when exposed to fire
Special Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Firefighting Instructions: Move containers from fire area if safe, cool exposed containers with water spray, prevent run-off into drains and waterways
Personal Precautions: Avoid breathing vapors or mist, ventilate area, evacuate unnecessary personnel, wear appropriate personal protective equipment (PPE)
Environmental Precautions: Prevent spillage from entering drains or watercourses, inform relevant authorities of large spills
Methods for Clean-Up: Absorb with inert material (e.g., sand, vermiculite), transfer to suitable closed container, clean spill area thoroughly with water and detergent, dispose according to local regulations
Special Disposal Considerations: Contaminated material should be managed as hazardous waste, do not use combustible cleaning materials
Handling: Use only in well-ventilated areas, avoid skin and eye contact, avoid inhaling vapors or mist, keep away from sources of ignition, do not eat, drink or smoke when handling
Storage Conditions: Store in tightly closed original container, keep containers in a cool, dry, well-ventilated area, seal drums after use, separate from incompatible materials (such as strong oxidizers and acids), protect from sunlight and heat
Specific End Uses: Industrial and laboratory use, flavor additive, perfumery
Engineering Controls: Local exhaust ventilation, eye wash stations, emergency showers near handling areas, explosion-proof equipment in hazardous locations
Exposure Limits: No occupational exposure limits specifically established, but maintain exposure as low as possible
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), protective goggles or face shield, lab apron or protective clothing, NIOSH-approved respirator for vapor exposure above recommended limits
Hygiene Measures: Wash hands and face thoroughly after handling, do not reuse contaminated clothing without washing, keep work area clean
