Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide.
Special Hazards: Combustion can produce carbon oxides, nitrogen oxides, and possibly toxic fumes.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing.
Advice for Firefighters: Approach in the direction of the wind, clear area of unnecessary personnel, prevent run-off to sewers.
Personal Precautions: Avoid breathing vapors or contact with skin and eyes. Use personal protective equipment.
Environmental Precautions: Prevent further leakage or spillage if safe to do. Avoid discharge into drains and surface water.
Cleanup Methods: Soak up with inert material (sand, diatomite), dispose according to local requirements, ventilate the affected area after material pick up.
Decontamination: Clean the area with water and detergent, mop up thoroughly.
Handling: Use only in well-ventilated areas. After handling, wash thoroughly before eating, drinking, or smoking. Wear protective equipment such as gloves, goggles, and proper clothing.
Storage: Store in a tightly sealed container, in a cool, dry, well-ventilated area. Keep away from sources of ignition and unnecessary heat. Do not store near food or animal feed.
Incompatible Materials: Strong acids, strong oxidizers, highly reactive chemicals
Engineering Controls: Use fume hoods or local exhaust ventilation to keep concentrations below occupational exposure limits.
Eye/Face Protection: Chemical safety goggles and face shield when appropriate.
Skin Protection: Wear protective gloves and long sleeves.
Respiratory Protection: Where exposure is possible, use a NIOSH-approved respirator.
Hygiene Measures: Keep away from food, drink, and animal feed. Wash hands before breaks and after handling the product.
