Everything you need to know about mandatory inspections of ATEX equipment

What is it, why is it mandatory, and for which equipment are ATEX inspections required?

Why is it mandatory?

ATEX equipment is used in industrial environments where flammable substances, gases or dust particles may be present. A defect in electrical or mechanical equipment can generate sparks, posing a serious explosion risk. The inspection of ATEX equipment is regulated by the NEN-EN IEC 60079-17 standard and focuses on preventing these risks.

Which equipment requires inspection?

The inspection requirement applies to all equipment certified for use in ATEX zones, including:

• Electrical installations in explosive atmospheres

• Pumps and motors used in ATEX zones

• Lighting and control panels for ATEX environments

• Mechanical systems that may generate sparks

• Detection systems and safety devices for ATEX zones

How does an ATEX inspection work?

Preparation

Before the inspection, it is assessed whether the ATEX equipment is accessible and whether relevant documentation—such as installation manuals, risk assessments and previous inspection reports—is available.

Inspection points

During the inspection, several aspects of the equipment are assessed, including:

• Electrical safety: Inspection of wiring, connections, and spark protection systems

• Mechanical condition: Assessment of wear, corrosion and seals that could increase the risk of explosion

• ATEX marking and certification: Verification that the equipment complies with the assigned ATEX categories

• Protection levels: Verification of IP protection, flame arrestors and temperature limitations

• Explosion risks: Assessment of the environment and potential hazards such as leaks or dust accumulation

Inspection report

After the inspection, you will receive a detailed inspection report outlining the findings. If the equipment meets all safety standards, an inspection certificate will be issued. If defects are found, you will receive recommendations for repair or replacement.

Inspection frequency for ATEX equipment

The required frequency of inspections depends on the ATEX zone in which the equipment is located:

• Zone 0 / Zone 20: In-depth inspection (D) annually or more frequently (high risk)

• Zone 1 / Zone 21: Detailed inspection (C) every 1–2 years (depending on usage)

• Zone 2 / Zone 22: Visual inspection (V) every 3 years (under favourable conditions)

• After installation, modification or repair: Immediate inspection before commissioning

Frequently asked questions about ATEX inspections

Why is an ATEX inspection important?

An inspection helps prevent defects in equipment from causing sparks or overheating in explosive environments.

Who is authorised to carry out ATEX inspections?

Only a qualified expert with demonstrable knowledge of explosion safety and ATEX standards may conduct inspections.

What happens if my ATEX equipment is not inspected?

Failure to carry out a mandatory inspection can lead to dangerous situations, liability in the event of incidents, and non-compliance with legal obligations.
