Combustible dust hazard control is the key to prevent combustible dust deflagration and explosion. Combustible dust hazard control includes dust control, ignition (heat) source control, operation control and workplace or space control. Proper controls can prevent dust explosion.

Once the initial dust explosion occurs, the secondary explosion seems likely to take place. The secondary explosion can be far more destructive than the primary explosion due to the increased concentration of combustible dust in the surrounding air. (more…)
