How do dust and gas explode?
The conditions necessary for an explosion or fire to occur are: the presence of a combustible substance, oxygen and an ignition source.There are upper and lower limits of the combustible concentration (gas or dust) in the atmosphere that are determinants of the possibility of an explosion being triggered. In the case of dust in particular, a particle size that improves dispersion in the air plays a fundamental role. When using industrial vacuum cleaners, air and therefore oxygen, is always present, and there are also dust clouds and possibly flammable gas or vapor. Therefore, two of the three elements that can generate the explosion are always present: air and a combustible material.
ATEX certified Nilfisk industrial vacuum cleaners eliminate the third parameter: the trigger. The vacuum cleaners are designed to prevent the triggering of any source of ignition, making vacuum cleaning operations safe.
