This report is a summary of the findings from physical characterization and testing the explosibility and flammability of dust collected during handling of white pellets as well as bark pellets. Explosions and fires are quite common in the industry processing wood, including the wood pellet industry, as can be seen in the diagram on the right hand side illustrating the officially recorded incidents in USA. It is of interest to notice the relatively small rate of incidents in the coal mining industry which traditionally has had a reputation of having many serious incidents.
