5. Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical, water spray, carbon dioxide
Unsuitable Media: High volume water jet (may spread product)
Specific Hazards: Burning may produce fumes of carbon oxides and silicon oxides
Special Protective Equipment: Firefighters should use self-contained breathing apparatus
Special Procedures: Cool closed containers with water spray, prevent runoff. Prohibit entry to sewers and drains

6. Accidental Release Measures

Personal Precautions: Wear gloves and goggles, ventilate area, avoid breathing vapors
Environmental Precautions: Block any entry to sewers, surface water, or drains
Containment: Absorb with inert material (sand, earth), clean up with non-sparking tools
Disposal: Collect for proper waste disposal by licensed facility
Decontamination: Wash area with soapy water, ventilate and monitor for residue

7. Handling and Storage

Handling: Minimize contact with skin and eyes, avoid ingestion or inhalation of vapor or mist, use only with adequate ventilation, wash thoroughly after use
Storage Conditions: Store in tightly sealed original containers, keep away from strong oxidizers and acids, store in cool, dry, well-ventilated area, avoid direct sunlight or freezing temperatures
Special Requirements: Use secondary containment to avoid accidental release, keep out of reach of children

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limits for major components
Engineering Controls: Use local exhaust ventilation where vapor or mist form, implement spill prevention
Personal Protective Equipment: Nitrile gloves, splash-resistant goggles, protective clothing, in case of spills use chemical-resistant boots
