In sawmill operations, combustible dust can accumulate on equipment, rafters, floors, and production surfaces. If the dust becomes airborne, it can create a serious fire or explosion hazard. Good housekeeping is essential, but some cleaning methods can unintentionally increase risk. One of the most common examples is using compressed air to blow down and clear dust. There are many challenges and risks with using compressed air for blowdown. It doesn’t actually remove dust; instead, it instantly generates a dense dust cloud creating a significant explosion risk. The dust gets redistributed, shifting from one place to another, spreading across machinery, product lines, and other sensitive areas. It can be forced into hidden spaces or up into rafters, making future cleanup more difficult. When hazards like static discharge or sparks combine with airborne dust, conditions for an explosion can develop quickly. …Combustible dust hazards are manageable when dust is prevented from becoming airborne and ignition sources are tightly controlled.
Wood products manufacturing operations have their share of hazards to workers. Identifying hazards, assessing the risk level and building controls are essential in both harvesting and manufacturing settings.
