Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Do not use high-pressure water jets.
Hazardous Combustion Products: Fluorinated compounds, hydrogen fluoride, nitrogen oxides, sulfur oxides, toxic gases such as carbon monoxide may form on combustion.
Fire-Fighting Procedures: Firefighters wear self-contained breathing apparatus and full protective gear. Approach from upwind to avoid hazardous vapors.
Specific Hazards: Thermal decomposition products may pose significant risks; closed containers may rupture due to heat.
Advice for Firefighters: Remove containers from fire zone if it can be done safely. Cool fire-exposed containers with water fog.
Personal Precautions: Ventilate area of spill. Wear personal protective equipment including gloves, goggles, protective clothing, and respiratory protection.
Environmental Precautions: Prevent product from entering drains, sewers, or watercourses. Notify authorities immediately in case of significant release.
Containment Methods: Absorb spill with inert material such as dry sand or earth. Avoid using organic absorbents that could react.
Clean-up Methods: Place absorbed material in appropriate waste container for proper disposal. Decontaminate affected area with water and detergent. Wash area thoroughly.
Safe Handling: Always use in well-ventilated areas. Avoid inhalation of dust or vapor. Prevent skin and eye contact by wearing proper protective equipment.
Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated place. Keep away from sources of heat, sparks, direct sunlight, and incompatible substances (strong oxidizing agents, acids, bases).
Hygiene Measures: Do not eat, drink, or smoke while handling this material. Wash hands and face after use. Remove and wash contaminated clothing before reuse.
Incompatibilities: Avoid storing with strong oxidizing chemicals, acids, or reactive halides.
Occupational Exposure Limits: No established exposure limits provided by OSHA, ACGIH, or NIOSH for this material. Treat as nuisance dust in the absence of specific guidance.
