If the wood dust is contained within a full or partial enclosure, the pressure build up can produce a destructive explosion. Its severity will depend on the type and concentration of the dust, the size of the source of ignition and the strength of the enclosure. Generally, the larger the volume of the exploding dust cloud, the more widespread its effects will be. It is important to ensure that wood dust does not escape from collection systems and be allowed to accumulate within workrooms.
