Wood dust consists of tiny particles of wood produced during the processing and handling of wood, chipboard, and/or hardboard. Worker exposure is high in many industries, including logging and sawmill operations, furniture and paper manufacturing, and construction of residential and commercial buildings. Operations within these industries, such as sawing, routing and turning; sanding, by machine and by hand; and using compressed air lines to blow dust off furniture and other articles before spraying are the most likely to produce high dust levels.
