Passive or active: Selecting an explosion protection method for your dust collector
After describing passive and active explosion protection methods for dust collectors, this article provides advice on how to choose a method for your application.
Nuisance dust accumulation on surfaces in a bulk solids plant is a dangerous safety hazard. In fact, the National Fire Protection Association (NFPA) and OSHA recognize that just 1/32 inch of dust over 5 percent of the workplace is enough fuel to propagate a secondary explosion after an initial combustion event. Addressing dust accumulation in your plant is a critical step in complying with government safety regulations for combustible dust hazards.
