Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam
Unsuitable Extinguishing Media: None known for this substance
Special Hazards: Product can decompose upon heating producing carbon monoxide, carbon dioxide, and nitrogen oxides
Protective Equipment for Firefighters: Wear full protective gear including self-contained breathing apparatus
Advice for Firefighters: Avoid inhalation of combustion products, ensure proper ventilation afterwards
Personal Precautions: Use gloves, laboratory coat, eye protection, suitable mask if airborne particles suspected
Environmental Precautions: Prevent release into water systems, drains, or soil
Cleanup Methods: Small spills: absorb with inert materials, place in chemical waste container
Decontamination: Wash spill area with soap solution, manage waste through approved disposal protocol
Other Precautions: Avoid dust generation, ensure proper ventilation throughout clean-up
Handling Conditions: Work in well-ventilated area, avoid contact with skin and eyes, minimize dust formation
Storage Requirements: Keep container tightly closed in dry, cool, well-ventilated space
Incompatibles: Strong oxidizing agents, acids or bases may degrade product
Maintenance: Store in clearly labeled containers, keep away from food and drink, ensure containers remain sealed except during use
