Combustible dust can produce two different types of fire hazard scenarios. Combustible dust is often either organic or metal dust that is finely ground into very small particles, fibers, fines, chips, chunks, or flakes. Commonly known examples of combustible metal dusts are aluminum and magnesium. Organic combustible dusts examples are wood dust; plastic dust; biosolids; organic dust, such as sugar, paper, soap, and textile dust.
Any combustible material can burn rapidly when in a finely divided form. Dust can become combustible under certain circumstances. If dust is suspended in air can become explosive. Organic material, such as sugar, flour, grain, or wood becomes highly combustible when mixed with air. Some material, like metals or non-organic materials, becomes combustible if the particles are a particular size and concentration.
Some workplaces have a higher risk of dust explosion since dust is created when materials are transported, handled, processed, polished, ground and shaped. Material moving across a conveyor belt is one part of the manufacturing process that needs examination since a flash fire or dust explosion is manufacturing process that requires analysis to avoid a dust explosion.
Combustible dust is created by abrasive blasting, cutting, crushing, mixing, sifting or screening dry materials. Metal processing of zinc, magnesium, aluminum, and iron are often in need of attention or a dust hazard anaylsis (DHA). Food, grain, and dairy manufactures are susceptible to combustible dust hazards since the buildup of dried residue from the processing of wet materials can also generate dusts.
Manufacturers should pay particular care throughout high-risk areas of the plant, such as mills, oil pump rooms, conveyors, motors, dryers, presses, sanders, and planers.
Three basic elements are needed to have combustible dust fire:
A dust explosion occurs when there are two other elements present:
Dust particles suspended in air is dispersion. Confinement happens when dust is in an enclosed or limited space.
Most of the normal production processes major manufactures use also create risk. The normal transportation of material down a conveyor belt or through a contained valve are hazards activities that we can easily mitigate against.
We help industries to safeguard against both primary and secondary explosions. A primary dust explosion occurs when combustible dust explodes. Most of these dust explosion takes place in a confined space like a container, room, or equipment processor. The secondary explosion is often far more destructive. Fire traveling down a pipe, into another room as fire seeks oxygen, or rising up a pipe often is the actual cause to the destruction of a factory or plant. Our products and solution protect against both primary and secondary explosions.
The Eximio Quick Suppression Water Mist systems are the new generation of technology that can mitigate the fire hazard in process areas and process equipment. These suppression systems are specially designed to quickly to extinguish fire and flash fires with minimum amounts of water. Small water droplets provide cooling, heat absorption, and inerting as they evaporate into steam. The goal of these systems isn’t to just contain a fire, but rather to extinguish it.
