What Is ATEX or Explosive Proof

What Is ATEX or Explosive Proof / How to choose perfect explosive proof devices?

Atex name generally was given two europian directives to controlling explosive atmospheres  

1. Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.                   
2. Directive 94/9/EC (also known as 'ATEX 95' or 'the ATEX Equipment Directive') on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

All Electrical equipment like junction boxes, sensors, actuators, chain hoist, and other pneumatic equipment can be referred to as spark-proof or Ex equipment.

In the europian market Before products that are intended to operate in potentially explosive atmospheres, manufacturers must ensure they meet the requirements of the ATEX Directive 2014/34/EU.

Based on atmospheric conditions Hazard zone classified into five different zones.

Hazardous Gas, Vapour and Dust Environments(Zone-0,1&2).

• Zone-0.  

              Normally Zone-0 consider as a mining area, an atmosphere where a  mixture of air and flammable substance in the form of gas, vapor & Dust. continuously present in the atmosphere for a long time. cole mining is a good example Atex Zone -0.

• Zone-1.

            A good example of Zone-1 is a petrochemical plant. an atmosphere where a  mixture of air and flammable substance in the form of gas, vapor & Dust. continuously present in the atmosphere for normal operation.

• Zone-2.

            A good example of Zone-2 is a production plant. an atmosphere where a  mixture of air and flammable substance in the form of gas, vapor & Dust. continuously present in the atmosphere for normal operation.
