ATEX SAFETY STANDARDS. The ATEX standard is designed to help prevent dust or gas explosions in industrial environments, including conveyor systems carrying cargo such as coal, grain, and fertilizers. Health and safety experts determine if there are areas or zones in industrial locations where there may be a risk of explosions.
Classifying hazardous areas into zones . Once an area has been identified as hazardous it should be classified into zones based on the frequency and persistence of the potentially explosive atmosphere. This then determines the controls needed on potential sources of ignition that may be present or occur in that area. These controls apply
Potentially hazardous locations are divided into Zones. 0, 1, 2 for Gas, Vapor, Mist. 20, 21, 22 for Dust. Torches approved for usage in these zones are divided in Categories 1, 2, 3 An accidental explosion in a hazardous location could mean serious injury for an employee.

surfaces into the expanding combustion zone. Heat transfer to the coal dust particles results in an exothermic reaction and expansion of the air in the entry. As the explosion progresses, the pressure wave continues to disperse entry dust, adding fuel to the explosion. Finer coal dust is more explosible and requires more rock dust to
