ATEX Level 2
Mechanical or electrical course

At an industrial site where an explosive atmosphere (ATEX) could occur, the operator is responsible for ensuring worker safety. This includes not only adapting the site’s design to reduce risks, but also installing ATEX equipment and removing potential ignition sources. Unfortunately, no matter how good the design is, inadequate installation or maintenance can alter ATEX equipment characteristics, and lack of knowledge on the part of the personnel involved can lead to hazardous conditions. To assure safety, it is essential for everyone to respect the specific rules relating to ATEX zones and that maintenance and installation conform to ATEX standards. To achieve this, every worker must undergo job-specific training. Our training courses are certified ISM-ATEX by Ineris and are aimed at those engaged in installation design, as well as maintenance staff, operators and supervisors.

The four-day level 2 training digs into the basic concepts of mechanics and electricity and goes into more detail on, for example, zoning, equipment selection, European legislation, maintenance, inspections, and cable selection.

The training covers similar content to level 1 but in more details. Additional issues are covered, such as:

  • How should I zone an installation?
  • When is an equipment certified by a notified body?
  •  Rules concerning conception of materials (the given rules follow the standard EN60079).
  • More details about protection modes:
    • intrinsic safety “i”,
    • increased safety “e”,
    • flameproof “d”,
    • pressurisation “p”,
    • liquid immersion “k”,
    • constructional safety “c”, etc.
  • Certification rules for assemblies.
  • What can I do with equipment dating from before 2003 to make it conform to the current ATEX directive?
  • How can I calculate the acceptable cable length for intrinsic safe equipment?
  • How should I measure the creep distance for increased safety equipment?
  • How should earthing be done?
  • Particular requirements for rotating equipment including fans.
  • Installation and maintenance of ATEX equipment: rehabilitation techniques, new parts, mechanical seals, belts, screws, bearings,etc.
  • Inspection and control of installations.
  • Practical case studies are discussed during training
  • Questionnaire at the end of the session to obtain the ISM-ATEX certificate.

Level 2 training is formulated by Ineris and recognised by the EU.

All persons directly managing workers in ATEX zones, such as senior technical maintenance staff and asset managers responsible for transformers.
