Hazardous Combustion Products: Sulfur dioxide, phenolic vapors, carbon monoxide, carbon dioxide
Protective Equipment: Chemical-resistant clothing, self-contained breathing apparatus
Specific Hazards: Thermal decomposition rapidly produces corrosive, toxic gases; product may flow after melting
Firefighting Procedures: Move containers away if safe, cool surrounding equipment, contain runoff to prevent soil, water contamination
Personal Precautions: Wear standard PPE (gloves, goggles, respirator if dusty), ventilate area
Environmental Precautions: Prevent spillage entering watercourses, drains, or soil
Containment: Absorb with inert material like sand or clay, do not use sawdust
Clean-Up: Sweep up, bag waste in suitable containers, decontaminate area with detergent and water
Disposal of Spilled Material: Dispose in accordance with regional, national, and local regulations for chemical waste
Additional Advice: Clean tools and protective equipment after use, notify relevant authorities if large quantities escape
Safe Handling: Avoid inhaling dust, contact with eyes and skin, use in well-ventilated areas, never eat or drink while handling
Storage Requirements: Store in cool, dry, ventilated places, away from strong acids, bases, oxidizers; keep containers tightly closed, upright
Material Incompatibility: Halogenated solvents, strong alkalis, oxidizing agents
Precautions: Label containers with contents and hazard warnings, enable secondary containment where possible
Good Practice: Rotate inventory to use oldest stock first, monitor for signs of degradation, swelling, or color changes
