RSPB – An explosive atmosphere can form in various places in wood processing plants. An explosion can occur directly during wood processing, where combustible dust is produced. Other risk areas may be wood material conveying systems, including belt, screw, and other conveyors. The greatest risk of combustible dust explosion is in dust extraction systems. An explosive atmosphere is constantly present in these systems and so is the risk of explosion.
During transport and handling of wood material, dust particles are dispersed. In combination with air, these particles create an explosive atmosphere. If the explosive mixture comes into contact with the ignition source, a devastating explosion can occur. The explosion is characterized by a quick rise in temperature and pressure, which can have destructive effects on both the production technology and the health and lives of the operating personnel.
