ATEX zoning – DRPCE


CentrExpert atex zoning, our methodology, our DPRE

Atex Zoning is one of the responses provided by the European Union to limit the occurrence of accidents such as Feyzin (explosion following a propane leak near a motorway, Rhône, 1966), Blaye (explosion of a silo cereals, Gironde, 1997),… To achieve good atex zoning, it is important to control a certain number of factors.

European regulations against the risk of explosions (directive n ° 94/9 / EC and directive n ° 99/92 / EC) have been transposed into French law in articles R4227-42 to 54 of the Labor Code.

These articles require any operator of an explosive atmosphere to:

  • Prevent the formation of an Explosive Atmosphere (ATEX).
  • Avoid their inflammation, if their formation cannot be prevented.
  • Mitigate the harmful effects.

For this, the operator must:

  • Subdivide into zones the locations in which ATEX can occur.
  • Establish and update an Explosion Protection Document – DRPE – integrated into the Single Document, which constitutes an assessment of the risks of explosion and an associated action plan.

CentrExpert will provide you with an experienced consultant to:

  • Identify the activities of your company likely to generate ATEX.
  • Carry out the ATEX zoning of these locations.
  • Establish an explosion risk analysis in each of these zones, based on the probability of igniting an ATEX zone and the severity of this explosion.
  • Draft the DRPE by establishing measures to ensure compliance with the recommendations of the Labor Code regarding explosions.

CentrExpert also supports you in carrying out an atex audit of macroscopic adequacy of electrical and non-electrical equipment present in the ATEX area. This atex audit is based on the markings accessible only on the equipment (engine plate, etc.).

CentrExpert can assist you in the implementation of a new activity likely to produce an ATEX by anticipating:

  • the choice of raw materials used
  • the means of control (eg setting up ventilation at a sufficient flow to control the ATEX risk generated by vapors of flammable liquids)
  • the choice of equipment located in the area
