Specific Hazards: Accumulated airborne dust can explode if ignited; product may smolder and re-ignite
Protective Equipment for Firefighters: Self-contained breathing apparatus, full turnout gear
Hazardous Combustion Products: Carbon monoxide (CO), carbon dioxide (CO2), organic aldehydes, fine particulates
Firefighting Procedures: Evacuate area; prevent dust cloud formation; cool containers with water; avoid breathing smoke and fumes
Personal Precautions: Avoid generating dust; ventilate area; use dust mask and safety glasses
Environmental Precautions: Prevent entry into drains and waterways; dust and debris may temporarily impact water oxygen levels
Methods for Containment: Scoop or vacuum spilled material; minimize dust formation; collect in appropriate containers
Methods for Cleanup: Use damp sweeping or an industrial vacuum designed for combustible dusts; avoid dry sweeping; wash area with water if required; dispose of spilled product responsibly
Reporting: No local or federal spill reporting requirements unless environmental contamination or fire risk arises
Safe Handling Practices: Use only in well-ventilated areas; avoid prolonged inhalation of dust; prevent formation of airborne dust clouds; keep away from sparks or open flames; handle with clean, dry hands
Hygiene Recommendations: Wash hands before eating, drinking, or smoking; do not eat, drink, or smoke near material
Storage Guidelines: Store in cool, dry, well-ventilated area; keep container tightly sealed to prevent dust
Incompatible Materials: Strong acids, strong oxidizers
Storage Temperature: Keep ambient, avoid extreme humidity or heat
Special Sensitivities: Keep away from moisture to prevent mold growth; avoid compressing material, which may promote self-heating
Occupational Exposure Limits: ACGIH TLV: Wood Dust (all species except Western Red Cedar): 1 mg/m3 (inhalable fraction, TWA 8 hr); OSHA PEL: 5 mg/m3
Engineering Controls: Exhaust ventilation, dust collection systems, local air extraction
Eye Protection: Safety glasses with side shields; goggles in dusty conditions
Respiratory Protection: NIOSH-approved dust mask or particulate respirator if dust levels exceed recommended limits
Skin Protection: Gloves for repeated or prolonged contact; protective clothing if allergic reactions documented
Environmental Exposure Controls: Avoid dust release; use spill containment procedures; monitor air quality in workspaces

Melting Point: Not applicable (decomposes on heating)
Boiling Point: Not applicable
Flash Point: > 200°C (closed cup, dust form)
Evaporation Rate: Not applicable
Flammability: Combustible solid; poses fire risk as airborne dust
Vapor Pressure: Not applicable

Stability: Stable under recommended storage and handling conditions
Reactive Conditions: Airborne wood dust can ignite in presence of spark or static; avoid high heat, open flames
Incompatible Substances: Strong acids, alkalis, oxidizing agents
Hazardous Decomposition: Thermal decomposition releases carbon monoxide, carbon dioxide, aldehydes, particulate matter
Polymerization: Product does not undergo hazardous polymerization
Shelf Life: 24 months when stored dry and sealed
Likely Routes of Exposure: Inhalation, skin contact, eye contact, accidental ingestion
Acute Effects: Irritation of eyes, nose, throat, skin in sensitive individuals

Aquatic Toxicity: Does not meet criteria for aquatic hazard; in large quantities, wood dust can consume oxygen in water, risking aquatic life
Biodegradability: Rapid; product breaks down by microbial action in soil and compost
Bioaccumulation Potential: Low; not expected in organisms
Soil Effects: Adds organic content if used as mulch or compost ingredient; excessive release may disrupt soil pH or microbial balance
Mobility in Soil: Low; material settles quickly, may clump in moist conditions
