NEW Guide – Understanding & Managing Combustible Dust – Download Now for FREE!

Glacier Technology has extensive experience building combustible dust systems for a wide range of applications. When considering combustible dust solutions, it is important to understand that there are two approaches – proactive and reactive.

Dust Fire and Explosion PentagonCombustible dust in a confined area will burn very quickly if it is ignited, and it is highly likely to explode. In the event of a combustible dust explosion, the initial explosion often dislodges additional accumulated dust, leading to secondary explosions. In many cases, the secondary explosions are actually more destructive, since they involve a higher volume and concentration of explosive dust.

OSHA describes the conditions under which a combustible dust explosion can occur as the Dust Fire and Explosion Pentagon. The pentagon elements include:

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

NFPA compliant combustible dust equipment and accessories deal with combustible dust explosion hazards either proactively or reactively. Knowing which type of system you need begins with understanding how the two approaches work.

Proactive Combustible Dust Solutions
proactive combustible dust accessories
Proactive accessories are designed to stop or reduce the chance of a deflagration event before it happens. Each of the elements in the Dust Fire and Explosion Pentagon are required for a combustible dust explosion. In the absence of one of those elements, the risk of a catastrophic explosion or fire will be averted or reduced.

Proactive devices are designed to prevent deflagration by taking one or more of the pentagon 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.

Reactive Combustible Dust Solutions

Reactive devices are designed for containment. This means that a deflagration event will be contained to minimize its impact, preventing further damage to people, equipment, and the facility.

Glacier Technology offers the CMAXX combined with proprietary IDA (In-Line Deflagration Arrester) DeltaMAXX filters. Using the CMAXX with IDA DeltaMAXX filters eliminates the need for expensive after filters, while providing an efficient and proven solution for isolating a deflagration and stopping a flame front.

Glacier Technology brings extensive experience and expert knowledge in developing combustible dust systems and in the successful navigation of OSHA and NFPA requirements. We are ready to assist you with a safe, compliant, and affordable system for your project. Contact us today!
