Dust Hazard Analysis
- Has a dust hazard analysis (DHA) been completed identifying fire, flash-fire, and explosion hazards throughout the facility? *
- Are areas where combustible wood dust can accumulate or become airborne identified and assessed? *
- Is the DHA reviewed and updated at the required interval or after process changes? *
Housekeeping & Dust Control
- Is dust accumulation on floors, beams, ledges, and equipment kept below the threshold layer depth through a housekeeping program? *
- Are dust collection systems designed, maintained, and operated to capture wood dust at the source? *
- Is cleaning performed using methods that avoid creating dust clouds (no dry sweeping or blowdown that suspends dust)? *
Ignition Source Control
- Is electrical equipment in dust-exposed areas rated and installed for the classified location? *
- Is a hot-work permit program in place controlling welding and cutting near combustible dust? *
- Are bearings, motors, and friction points inspected and maintained to prevent overheating ignition? *
Explosion & Fire Protection
- Are dust collectors and enclosures protected by explosion venting, suppression, or isolation as determined by the DHA? *
- Are spark detection and extinguishing systems provided on conveying systems where warranted? *
- Is fire protection (sprinklers, extinguishers) provided and maintained appropriate to the mill hazards? *
