What is ATEX and why is training a legal requirement?

ATEX is the name of two EU directives that regulate how work and equipment in potentially explosive atmospheres should be handled. The name comes from the French expression "ATmosphères EXplosibles". Whether you work in electrical installation, industry, process or maintenance, it's important to understand what ATEX means - and why training on the subject is not only important, but actually a legal requirement.

What does ATEX mean?

There are two key ATEX directives:

ATEX Directive 2014/34/EU - regulates requirements for equipment and protective systems used in explosive atmospheres.
User Directive 1999/92/EC - sets requirements for the design of the working environment where there is a risk of explosion, including safety measures and training.

Explosive atmospheres can occur in environments where flammable substances are handled, for example in the chemical industry, paint shops, workshops, refineries, silos or electrical installations in sensitive zones. Both EU directives and Swedish authorities, such as the Swedish Work Environment Authority, require staff working in such environments to have documented competence.

Why is training a legal requirement?

According to AFS 2023:10, the Swedish Work Environment Authority's regulation on work in potentially explosive atmospheres, everyone who is present or works in areas where explosive atmospheres may occur must have knowledge of explosion risks and protective measures. This also applies to contractors and temporary staff.

In addition, SRVFS 2004:7 (MSB's regulations) requires that there is a clear classification of risk areas and that everyone working in them is aware of the safety procedures. ELSÄK-FS 2016:2, which applies to electrical equipment in potentially explosive environments, also requires electrical installers to have the right skills.

So it's not just about preventing accidents - it's about complying with legal obligations. Employers who do not ensure that their staff have the correct ATEX training can be held liable in the event of an incident.

What does ATEX training include?

A good basic training in ATEX provides knowledge about:

Potentially explosive atmospheres and how zone classification works (zone 0, 1, 2)
Ignition sources, protection levels and technical measures
Ex marking and choice of approved equipment
Safe installation, operation and maintenance in ATEX zones
Rules according to the ATEX directives, AFS 2023:10 and SRVFS 2004:7

The training usually ends with a knowledge test, and upon successful completion, you will receive a diploma or certificate showing that you meet the requirements.
