What does ATEX mean?
ATEX stands for ATmosphères EXplosibles - the European directive for explosion protection.
It regulates which devices and protective systems may be used in potentially explosive atmospheres.
The most important basis:
- ATEX Product Directive (2014/34/EU) - for manufacturers of appliances
- ATEX Operating Directive (1999/92/EC) - for operators of installations
Only ATEX-certified devices may be used in corresponding zones - otherwise there is a risk of accidents and legal consequences.
Why ATEX-certified devices are crucial
1. Avoidance of ignition sources
ATEX devices are built in such a way that they do not generate any ignitable energy or surface temperature - even in the event of a fault.
2. Legal compliance and liability
The use of non-certified technology is prohibited in potentially explosive atmospheres.
Particularly problematic: time and again, devices with fantasy certificates appear - usually from manufacturers outside the EU, which allegedly certify ATEX conformity. These certificates often do not come from notified bodies and have no legal validity whatsoever.

Importers and operators are often not aware of the actual legal situation - but that doesn't matter in an emergency:
👉 The responsibility lies with the operator - often the managing director or owner personally.
In plain language:
- Anyone operating non-compliant ATEX devices violates EU law.
- In the event of damage, liability with private assets is imminent.
- Insurance companies can also refuse benefits.
3. Personal protection
ATEX-compliant devices protect employees from explosions, fires and health risks - and ensure a safe workplace.
4. Protection of assets and investments
An explosion can destroy entire production lines. The correct use of equipment not only protects people, but also machines and infrastructure.
5. Betriebssicherheit & Versicherung
Only certified technology is recognized by professional associations and insurers. Damage caused by non-compliant technology can lead to exclusion of liability.
Practical examples
- In a sewage treatment plant, a smartphone may only be taken into the area with an explosive atmosphere if it is ATEX-certified - for example near digesters or gas tanks where methane and hydrogen sulphide can escape.
- In the paint shop, the compressed air switch or sensor must also be explosion-proof - otherwise there is a risk of ignition.
- Maintenance teams in Zone 1 require tools, lights and measuring devices with appropriate type of protection.
How do you recognize an ATEX-certified device?
Look out for the Ex symbol and the associated marking, e.g:
II 2G Ex ib IIC T4 Gb
This label indicates:
- Device group and category (II 2G - Zone 1)
- Type of protection (e.g. Ex ib - intrinsic safety)
- Ignition group (IIC) and temperature class (T4)
- Device zone suitability (Gb)
Conclusion
ATEX-certified devices are not an option - they are mandatory.
They save lives, prevent damage and ensure the legally compliant operation of systems.
Our tip: Only buy ATEX devices from certified specialist dealers - and check whether the certificates come from a recognized, notified body from the EU.
