Where Is ATEX Required? Understanding ATEX Compliance Across Industries

Updated: November 4, 2024

ATEX, short for “Atmosphères Explosibles,” refers to the European Union directives that regulate equipment used in potentially explosive atmospheres.
These standards ensure that machinery and protective systems can operate safely in environments containing flammable gases, vapors, or combustible dusts.

For companies operating in hazardous conditions, understanding where ATEX certification is required—and choosing ATEX-certified motors like those from Atlas Copco—is essential for compliance, efficiency, and worker safety.

What Is ATEX and Why It’s Important

The ATEX Directive 2014/34/EU defines the safety requirements for electrical and mechanical equipment intended for use in explosive atmospheres.
It ensures that all components—such as motors, tools, and pumps—are designed to prevent ignition sources, such as sparks or high surface temperatures.

Complying with ATEX regulations:

• Protects workers in hazardous areas

• Reduces explosion risk and downtime

• Meets mandatory EU safety requirements

• Demonstrates commitment to safe, sustainable operations

Industries That Require ATEX Compliance

ATEX certification applies across multiple sectors where explosive atmospheres can occur. Here are the main industries where ATEX compliance is mandatory:

🔹 Oil and Gas

• Offshore and onshore production

• Refineries and petrochemical plants

• Gas storage and transfer systems

🔹 Chemical and Pharmaceutical

• Chemical processing and mixing

• Pharmaceutical formulation and packaging

• Solvent storage and handling

🔹 Food and Beverage Processing

• Flour mills, grain silos, sugar refineries

• Powder handling and spray drying

• Breweries and distilleries

🔹 Mining and Mineral Extraction

• Coal mines and material handling areas

• Dust control and ventilation systems

🔹 Power Generation and Waste Management

• Coal, biomass, and gas-fired power plants

• Waste treatment and recycling facilities

In all these industries, ATEX-certified motors play a crucial role in powering production equipment safely within explosive zones.

ATEX Zone Classifications Explained

ATEX divides hazardous areas into zones based on how frequently and for how long an explosive atmosphere may exist.

For dust (solids like flour or coal), the equivalent zones are Zone 20, 21, and 22.

Each zone determines which type of ATEX-certified motor or equipment can be safely installed.

ATEX Compliance: Key Requirements for Businesses

To comply with the ATEX Directive, companies must follow specific safety and documentation procedures:

1. Risk Assessment
   Identify potential explosive atmospheres and classify each area into the correct ATEX zone.

2. Certified Equipment Selection
   Use ATEX-certified motors and tools, such as Atlas Copco air motors, that match the required zone classification.

3. Installation and Maintenance
   Follow manufacturer guidelines for installation and perform regular maintenance checks.

4. Employee Training
   Train all personnel on ATEX awareness, safe operation, and emergency procedures.

5. Documentation and Records
   Maintain risk assessments, inspection reports, maintenance logs, and training records to demonstrate compliance.
