Strict regulations apply in Ex zones - but not for everything.
There are clear specifications for devices and systems in potentially explosive atmospheres. Many people therefore assume that every tool used must have ATEX certification. However, this is not the case - nor is it the intention. Here we explain why this is the case and how you can still ensure that tools in Ex zones are not a source of ignition.
📘 Was ist ATEX überhaupt?
ATEX describes two EU directives:
- 2014/34/EU (Equipment Directive): for equipment and protective systems in potentially explosive atmospheres
- 1999/92/EC (Operating Directive): for safe operation in these areas
Tools such as hammers, screwdrivers or pliers are generally not considered "appliances" for the purposes of the directive, as they do not have their own energy source and do not represent a potential ignition source - provided they are used properly.
❌ Warum gibt es keine ATEX-Kennzeichnung für Werkzeuge?
Tools do not even have to have an ATEX certificate - because:
- They do not fall within the scope of Directive 2014/34/EU.
- Their safety depends on the material used and how it is used - not on a certification body.
- An "EX" symbol on a tool is not an official test mark and has no legal significance.
Some manufacturers nevertheless mark their tools with an "EX" - as an indication of their intended use in Ex zones. However, this is no substitute for testing and safe handling.
✅ Was Sie noch beachten müssen
Even without ATEX marking, clear criteria must be observed:
- Spark-free materials, e.g. aluminum bronze or copper-beryllium (BeCu)
- Mechanically stable processing
- Antistatic properties, especially for handles
- No excessive friction, no overheating during use
🧪 Anmerkung aus der Praxis: BAM-Zertifikat
Some manufacturers have their tools independently tested. Our X-Spark tools are certified by the BAM (Federal Institute for Materials Research and Testing).
It confirms:
- the use of suitable materials
- the behavior under mechanical load
- Suitability for use in potentially explosive atmospheres
In this way, we offer our customers transparency and safety - even without official ATEX approval.
🧯 Fazit
ATEX applies to appliances - not to classic hand tools. Nevertheless, tools must also be safe and suitable for use in potentially explosive atmospheres. The decisive factor is
- the right material
- Correct handling
- and if required: reliable evidence, e.g. from testing bodies such as BAM
This means that even small tools can offer great safety.
