Traditional housekeeping methods like sweeping and blowing with compressed air are not enough to keep your facility free from combustible dust, they actually make the dust problem worse.
Sweeping or blowing the dust not only spreads the dust but also makes it airborne and this raises the chances of a combustible dust explosion.
This is why you need specialized and approved vacuums for getting rid of combustible dust and other explosive particles.
Will any vacuum do?
This is a question posed by many manufacturers but the answer is, not just any vacuum will work. Reason being, most of these vacuums have metal parts and electric motors and, therefore, can produce dangerous sparks.
Your vacuum should be certified
You should only go for a vacuum that is explosion proof. Such a vacuum is properly grounded from the internal mechanics to the outer shell and is also made of stainless steel, a non-sparking material.
You should be cautious when buying industrial vacuums that are fitted with anti-static features and accessories but they too, don’t work.
Buying a certified and approved vacuum is the only way to get a product that actually works.
Your combustible dust explosion-proof vacuum dealer should offer certification that the vacuum that you acquired can work in an NFPA-classified environment.
With this certification, you are guaranteed that every part of the vacuum meets all the set standards for preventing fire hazards and shock.
The right vacuum should have a multi-layer and graduated system for filtration and use fine anti-static fibers to trap and hold particles in the vacuum.
Won’t the dust be exhausted back into the air?
It can with low-end vacuums but a certified one makes use of ULPA or HEPA filters that are fitted after the motor to the exhaust part. Quality filters are highly effective and they trap even the smallest particles.
This is another area that should be taken into account when buying an explosion-proof vacuum. Although OSHA targets companies handling dry solids, the maintenance plants are also being focused on.
A wet model explosion-proof vacuum should be used when collecting explosive or flammable chemicals.
