Specific Hazards: Emits toxic fumes (carbon monoxide, carbon dioxide, phenolic compounds) under fire conditions, combustible dust risk if suspended in air
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing
Special Procedures: Use water to keep fire-exposed containers cool, collect contaminated fire water separately, prevent run-off into sewers and waterways
Personal Precautions: Wear chemical-resistant gloves, goggles, respirator if dust is present, avoid contact with skin and eyes, do not breathe dust or vapors
Environmental Precautions: Contain spill to prevent release into soil and waterways, cover drains, notify authorities if large release occurs
Methods for Cleanup: Sweep up or vacuum spilled material, use non-sparking tools, avoid generating dust, place in suitable sealed containers for disposal, wash area with water and detergent after cleanup
Reference to Other Sections: See Sections on exposure controls and disposal for further information
Safe Handling: Use only in well-ventilated areas, avoid dust generation, handle with appropriate personal protective equipment, never eat, drink, or smoke in storage or work area, always wash hands before breaks or at end of shift
Storage Conditions: Store in cool, dry, well-ventilated area, keep container tightly closed, protect from moisture and ignition sources, segregate from oxidizing agents, acids, and bases
Incompatibilities: Strong oxidizers, acids, alkalis, exposure to light or high temperatures may cause degradation
Specific End Use(s): Industry and laboratory use only, not for household purposes
Occupational Exposure Limits: OSHA PEL: 10 mg/m³ (total dust), ACGIH TLV: 10 mg/m³ (inhalable fraction)
