ATEX Level 0
Fundamentals of rules and principles

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.

  • What is an explosion?
  • General information about ATEX: industrial risk, legal obligations
  • Setting fires and explosions: LIE, LSE, EMI, Kst, Kg, Pmax
  • Ignition mechanisms: friction, static electricity, impacts, overheating
  • European directives: Directive 2014/34/EU guidelines, marking equipment, related documents, zoning
  • Overview of modes of protection ATEX equipment: What do I need to know?
  • ATEX zone intervention rules: general rules, tools, protective clothing.

All workers in ATEX zones.
