AB Factors that influence the explosiveness of wood dust, like particle size distribution, moisture content andmicroscopic structure, have been characterised. Sawdust flammability has been tested in a Hartmann tube. TheMinimum Explosive Concentration and Minimum Ignition Temperature of dust clouds and layers have also beenmeasured. Dust granulometry linked to the regularity of its structure and moisture are the essential parameters togenerate or not an explosive atmosphere. Smaller particle size dust with a lower moisture content is much morelikely to create an ignition and/or explosion risk. The samples have been classified into two groups, thosecollected from cutting processes and those found in the ventilation ducts or deposited in the facilities. The mostdangerous samples are those from Group 2. In some cases, dust samples up to 35 % moisture or with particle sizegreater than 500 µm at maximum dryness are able to produce an explosion.
