Wood dust is a byproduct of all wood manufacturing. Thus, all wood processors have dust management for safety reasons in common. For a dust explosion to happen, all that is required is a single spark from a hot surface or an electrical device. When the dust disperses and mixes with atmospheric oxygen, ignition in an enclosed or contained area causes an explosion. However, it is often not the first reaction that is devastating, but the much larger amount of dust aroused by the blast wave. This can ultimately lead to a chain reaction that can potentially destroy a whole plant. If there is a risk of accumulating wood dust, the main hazard control measures are good housekeeping, well maintained equipment to reduce any ignition risk, and existing controls to reduce the effects of an explosion, such as vents or dust collectors.
