Combustible dust areas
The HELIOS SAFE INDUSTRY IP66 heater has been designed, built and tested to operate in complete safety in environments with potentially explosive atmospheres and manufactured and certified in compliance with Atex regulations.
What is combustible dust and why are ATEX heaters are required in these areas?
Combustible dust is any material (finely divided solid particles) that has the ability disperse in air and catch fire and explode when exposed to an ignition source. Combustible dust may include materials that are in the physical states of powders, flakes, fines, fibers, etc.
Combustible dusts can include:
Some of these materials are not “normally” combustible, but they can burn or explode if the particles are the right size and in the right concentration.
Therefore any activity that creates dust should be investigated to see if there is a risk of that dust being combustible. Dust can collect on surfaces such as rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment. When the dust is disturbed and under certain circumstances, there is the potential for a serious explosion to occur. The build-up of even a very small amount of dust can cause serious damage.
