Proactive and Reactive Combustible Dust SolutionsCombustible dust equipment accessories designed to meet NFPA requirements fall into two primary categories – proactive and reactive. Proactive accessories are designed to prevent a deflagration event or reduce the chance of one occurring. Reactive devices are engineered to contain a deflagration event, or minimize the damage it can inflict upon people, equipment, and other property.

If combustible dust in a confined area is ignited, it will burn very rapidly and possibly explode. An initial explosion in an area where dust has accumulated may dislodge more accumulated dust or damage a containment system, leading to one or more secondary explosions. These secondary explosions can be far more destructive due to the increased quantity and concentration of combustible dust.

Proactive DevicesProactive Devices

OSHA describes the conditions under which a combustible dust explosion can occur as the Dust Fire and Explosion Pentagon. Elements required for a combustible dust explosion include:

  • Combustible dust
  • Ignition source
  • Oxygen in air
  • Dispersion of dust particles in sufficient quantity and concentration
  • Confinement of the dust

If one of the elements of the explosion pentagon is missing, a catastrophic explosion or fire will be prevented. Proactive devices are all about preventing deflagration by taking one or more of these elements out of the equation. Glacier Technology offers spark detection and extinguishing systems, and spark baffles as proactive accessories that can be incorporated into a system.
