ATEX certification explained: what it really means for your tools

If you’re working in explosive environments — whether it’s a chemical plant, offshore platform, or refinery — you’ve probably heard of ATEX certification. But what does it actually mean when a tool is ATEX-certified? And more importantly: how does it impact your daily operations, safety compliance, and choice of equipment?

What is ATEX and why should you care?

ATEX stands for “Atmosphères Explosibles,” and refers to two European directives that regulate equipment and work in explosive atmospheres. If you’re operating in Zone 0, 1, or 2 (gas) or Zone 20, 21, or 22 (dust), you are legally required to use equipment that complies with ATEX standards.

An ATEX-certified tool has been rigorously tested to ensure it does not create ignition sources — such as sparks, high surface temperatures, or static discharge — even in hazardous conditions. In short: ATEX certification is not just a label — it’s your license to operate safely in explosive zones.

What makes a tool ATEX-certified?

To qualify for ATEX, a tool must meet strict criteria:

• Spark-free operation: no hot sparks or friction-induced ignition
• Low surface temperature: so it won’t ignite flammable gases or dust
• Antistatic or non-conductive materials
• Independent testing and documentation: issued by a Notified Body

For example, all our grinding files and cutting discs are certified for use in Gas Zone 1 and 2, meaning they can be used safely in environments with a high risk of flammable gases.

Don’t be fooled: Not every “non-sparklinkg” tool is ATEX-approved

There’s a common misconception in the industry: that non-sparking tools = ATEX-compliant. That’s not necessarily true. Just because a tool is made of non-ferrous material (like brass or bronze), doesn’t mean it has been tested and certified under ATEX directives.

Only officially certified tools guarantee full compliance and safety in Ex-zones. Like the tools from Allmet Safety Tools.

How ATEX-certified tools benefit your operations

✅ Work safely in explosive zones
You reduce the risk of ignition during maintenance, grinding, cutting or surface prep — even in confined or poorly ventilated areas.

✅ Avoid downtime and shutdowns
Many ATEX-approved tools can be used during live operations, meaning less production stop and faster turnaround.

✅ Meet legal and insurance requirements
Working with the correct tools protects not only your workforce, but also your business reputation and liability position.

✅ Reduce need for Hot Work permits
ATEX tools often eliminate the need for complex permit procedures, simplifying planning and improving efficiency.

ATEX tools in action: Real results from the field

“The work went really well with very low noise and very little vibration. We are all in all very satisfied with the tools – we saved about a week’s worth of work.”
— Bjørn Erik Dahl, Aker Offshore Partner, Material Coordinator

Our clients consistently report improved safety, faster work, and less disruption during maintenance jobs in ATEX zones.

How to choose the right ATEX-certified tool?

It depends on:

• Your zone classification (Gas or Dust, Zone 0/1/2)
• The material you’re working on (stainless steel, carbon steel, aluminum, etc.)
• The task at hand (grinding, cutting, bolt removal, flange prep)

That’s why we always recommend speaking to one of our specialists before making a decision.
