Dust clouds, laboratory tests

The first stage of a dust explosion hazard assessment is to determine whether the dust will explode when dispersed as a cloud. The combustibility of a dust can be assessed by conducting an explosion classification test on a representative sample of the dust. In this laboratory test the observation of flame propagation determines whether or not a suspended dust is capable of initiating and sustaining an explosion. It should be... 

The sensitivity of a dust cloud to ignition by different ignition sources could be determined through appropriate laboratory tests.

The second involved the production of a ricin dust cloud, but due to limited amounts of ricin being produced and the inefficient delivery via the respiratory tract, little work seems to have been pursued in this means of dissemination. Although both approaches were laboratory tested, neither was perfected for use in Europe before the end of the war.29 Protective Equipment...
