In some manufacturing industries it can be a significant fire hazard and source of occupational dust exposure.
TheCleverSpice: Sawdust (or wood dust) is a by-product or waste product of woodworking operations such as sawing, sanding, milling, planing, and routing. It is composed of small chippings of wood. These operations can be performed by woodworking machinery, portable power tools or by use of hand tools. Wood dust is also the byproduct of certain animals, birds and insects which live in wood, such as the woodpecker and carpenter ant.
as the sawdust falls due to the influence of gravity one must wonder why did the human brain decide to place sawdust? what is sawdust? why is sawdust?
