Working Safely in Explosive Atmospheres

In many European industrial environments, combustible gases, vapours or dusts can create conditions where a single spark can cause a serious incident. Ensuring that people and assets are protected requires meticulous planning, the right equipment and strict adherence to proven safety practices. In this article we would like to introduce the key concepts for working safely in explosive atmospheres across EU worksites, laying the groundwork for understanding the standards and solutions that keep your operations compliant.

What is ATEX and why do worksites need it?

ATEX stands for “ATmosphères EXplosibles” and refers to the EU directives that govern equipment and protective systems used in potentially explosive atmospheres. EX is the term we use for the zone; in this area, you can only use ATEX-certified equipment. The ATEX 2014/34/EU Directive sets the standards for equipment, while ATEX 1999/92/EC addresses workplace safety.

You’ll need ATEX-compliant equipment and tools if your site includes:

• Flammable gases or vapours
• Combustible dusts
• Volatile substances under pressure

Industries commonly requiring ATEX equipment include:

• Oil & Gas
• Chemical and pharmaceutical production
• Wastewater treatment plants
• Food and beverage processing
• Paint and coatings facilities

Why ATEX matters in industrial worksites

Explosive atmospheres are a serious risk in many industries, from petrochemical and pharmaceutical to food processing and wastewater treatment. To operate safely and compliantly, it's essential to use ATEX-certified equipment in these hazardous environments.

At United Rentals, we provide a comprehensive range of ATEX-rated rental products to help you maintain productivity without compromising safety or compliance.

Understanding EX Zones

Hazardous areas are divided into zones based on how often explosive atmospheres are present:

• EX Zone 0: An explosive atmosphere is continuously or frequently present for long periods.
• EX Zone 1: An explosive atmosphere is likely to occur occasionally during normal operation.
• EX Zone 2: An explosive atmosphere is unlikely to occur, and if it does, it will exist only for a short duration.

Accurately identifying and classifying these zones is critical for implementing effective safety measures and selecting the right certified equipment.

Safety Challenges in EX Zones

Working in EX zones brings challenges for both safety and risk management. It is essential to understand the specific hazards in each area and implement the right technical and organisational measures to protect both personnel and installations.

To manage these risks effectively:

• Use certified equipment: All equipment and tools must meet strict ATEX standards to avoid ignition sources.
• Ensure training and awareness: Regular instruction ensures personnel know the risks and follow safe work practices.
• Conduct risk analysis: Defining each zone and documenting control measures in an Explosive Safety Document (EVD) ensures compliance and safety.
