Dust explosions can't happen here - can they?

 

The question of the probability of a dust explosion has been asked many times. However, too few companies go further to actively prevent risks of dust explosions.

What is ATEX?
The terms "ATEX classification", "ATEX zones" and "Dust classification" come from the ATEX Directives. ATEX is an abbreviation for the french term "ATmosphères EXplosible" and refers to atmospheres that are potentially explosive.

When does a dust explosion occur?
Explosive atmospheres arise when sufficient (LEL, Lower Explosion Limit/MEC, Minimum Explosible Concentration) combustible dust distributed in the air (oxygen) in an enclosure is combined with a ignition source. Many common substances present in industrial processes are explosive/combustible if they are or becomes atomized into small particles. Examples of substances are coal, flour, cereals, wood, cotton and plastics.
Metal particles from aluminium, titanium and magnesium are especially dangerous as they are not only incinerated in the event of an explosion or fire, they can also react with moisture and thus release hydrogen which has a very low ignition energy (MIE, Minimum Ignition Energy).

What does the law say?
Within the EU, all equipment intended for use in an area where an explosive atmosphere may occur shall comply with the requirements of the Product Directive. The directives apply to manufacturers of equipment to be installed in potentially explosive areas (Product Directive 2014/34/ EU) and to ensure the safety of the working environment for personnel in the potentially explosive atmosphere (OSH Directive 1999/92/EU).
