Residual Dust and Dust Collection Systems: Diffusing a Ticking Time Bomb in Your Business

Dust, particles and fibers floating around in a home or industrial workshop can often pose a lot more than just a nuisance or inconvenience. Dust from wood working, carving, sandblasting, drywall, ceramics, metals and others can cause a variety of allergy and respiratory issues, that range from aggravating to life threatening, and because of this, many business owners do employ vacuums and other systems, respirators, etc that get rid of the majority of the dust before it becomes a problem. There is a common problem, however, in many home and industrial shops that frequently have dust pollution: residual dust (what’s left over afterward, accumulations, etc).
 
First, if you don’t have a quality particle filtration system (consisting of source capture duct extractors and room air filtration units) and you routinely have airborne dust, fibers and particles floating around, it’s very important to your safety and health, the safety of your employees and the life of your business to make sure to remove those pollutants. This is easily accomplished by consulting an industrial air filtration or dust removal specialist and purchasing the right combination of units for your application.
 
Second, one of the big problems small and large workshops encounter is residual dust, which silently causes illness and can cause explosions without warning.  Wood dust (and particles from a lot of other materials easily become airborne) is very similar to grain dust, and I’m sure you’ve heard of grain silo explosions. Well, if you don’t have a dust removal system in place, this can easily happen in a workshop. And even if you do have vacuums or maybe not enough dust filtration units in place, it can still happen from the residual dust that is left over or not captured by those vacuums or other units.
 
 Dust explosions (deflagration) typically require five conditions to be met for them to occur: 1) combustible dust, 2) dust suspended in the air at a sufficiently high concentration, 3) a confined space 4) oxygen or other oxidant, and 5) any ignition source, such as a spark, cigarette lighter, torch or other sources. Dust from coal, sawdust, and magnesium are some of the most ‘ignitable’, but grain, flour, sugar, even powdered metals like aluminum and titanium can quickly cause a dust explosion, if the other factors above are present. Usually, there’s always oxygen present, and then all that’s really needed is an ignition source—which, in a workshop, can come from multiple sources. The problem with the concentration factor is you don’t know exactly when the proper amount of dust is suspended in the air—but it’s better to just not take the chance, as a dust explosion can destroy your business and cause loss of life.
 
The best course of action is to have source capture  particle filtration system in place at the machines where the dust is being produced, but also have the appropriate number of room particle filtration units running as well, to give you the Federal or State OSHA required number of clean air changes per hour (to keep the air clean and safe, and avoid hefty OSHA fines).
 
Many business owners will have source capture units in combination with cyclone dust collectors attached to the central HVAC system to remove any residual dust and prevent sudden dust explosions or deflagrations. Quality dust collectors are tax deductible expenses, too, and usually classified as equipment that can be used as collateral for loans, so that’s two more reasons to go ahead and get the units or systems in place to make sure you and your employees are protected.
