An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, an explosion could take place.
Different international regulations were created to avoid or minimize the risks of an explosion, like International IECEx directive, European ATEX Workplace Directive (Directive 99/92/EC) or European ATEX Equipment Directive (Directive 94/9/EC), which implies all devices installed in a potential hazardous area.
These hazardous areas are classified according to the degree of risk of an explosion taking place, identifying if the risk comes from a flammable gas mixture or from dust.
In every company, the plant manager is responsible for evaluating the risks present at the site, and the implementation of the appropriate equipment in each zone identified.
