5. Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide
Unsuitable Extinguishing Media: Direct water jet may spread product
Specific Hazards: May produce carbon oxides under fire conditions, irritating fumes possible
Protective Equipment: Firefighters require self-contained breathing apparatus, full protective gear
Special Procedures: Cool exposed containers with water spray, avoid runoff to drains or water courses
Explosion Data: Not explosive, does not form flammable vapors at ambient temperature

6. Accidental Release Measures

Personal Precautions: Wear gloves, eye protection, suitable clothing, avoid vapors
Environmental Precautions: Prevent entry into sewers, water courses, soil; contain spill to limit environmental impact
Small Spills: Absorb with inert material such as sand, collect in suitable containers
Large Spills: Dike and contain spill, collect with non-sparking tools, ventilate area
Cleanup Methods: Wash remaining residue with water and detergent, dispose according to local guidelines
Reporting: Notify authorities if spill affects public waterways or environment

7. Handling and Storage

Handling Precautions: Avoid contact with eyes, skin; do not breathe vapors; use in well-ventilated areas
Storage Conditions: Store in tightly closed containers, keep in a cool, dry, well-ventilated place, away from incompatible materials such as strong oxidizers
Suitable Materials: Stainless steel, polyethylene, glass
Unsuitable Materials: Copper, aluminum, rubber composites
Safe Handling Advice: Clean spills immediately to prevent slip hazards, avoid static electricity buildup
Other Precautions: Keep away from food and drink, use only as intended

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limits under OSHA, ACGIH, or NIOSH for these components
Engineering Controls: Local exhaust ventilation or general ventilation to maintain air concentrations below exposure guidelines
Personal Protective Equipment: • Eye Protection: Safety goggles or face shield
• Hand Protection: Chemical-resistant gloves
• Skin Protection: Long sleeves, closed footwear
