No security shortcuts
In environments where flammable gases, vapours or combustible dust are present in the air (from paint shops and pumps to silos and various EX rooms), completely different rules apply. Standard electrical installations are not sufficient here. Even static electricity, an inappropriate switch or an overheated lamp can trigger a devastating explosion.
At Volting, we carry out highly specialized inspections and measurements of installations in explosion-proof areas. Our experts carefully check that your protective equipment is installed correctly and that your system excludes the possibility of ignition 100%.
What exactly does an Ex check require?
Suitability of ATEX equipment
We check whether the built-in elements (electric motors, sensors, lamps) are actually certified and suitable for the specific danger zone in your plant.
Grounding and Potential Bonding Measurements
The most common "silent" cause of explosions is static electricity. We carefully check that all machines, pipes and metal parts are impeccably grounded so that the static charge is safely discharged.
Test of spark circuits
We check installations that are designed in such a way that, even in the event of a short circuit or fault, they cannot release enough energy to ignite an explosive air mixture.
Visual inspection of tightness and mechanical damage
Searching for damaged housings, cracks, missing screws, and worn cable glands through which hazardous gas or dust could enter electrical equipment.
When are Ex measurements necessary and legally mandatory?
The legislation (Explosion Protection Rulebook) is extremely strict in this area and does not allow deviations. Measurements are mandatory:
1. First measurements (before start-up)
Immediately after the construction or processing of the technological process – obligatory before a hazardous substance (gas, liquid, dust) is even released into the room.
2. Strict periodic measurements
Regular inspections at specific, often very short intervals, which are strictly defined in your Explosion Hazard Study.
3. After each procedure or malfunction
Engine replacement, lamp replacement or any refinement of the installation in the Ex Zone immediately requires re-checking and confirmation of safety.
In explosion-prone premises, impeccable documentation is not just a formality – it is your only protection and proof of the legality of operation.
With our measurement protocols, you can ensure:
- Compliance with inspection requirements: Labour inspectors and technical inspectors in Ex zones carry out stricter controls. Our documents are proof that the facility operates in accordance with regulations.
- Basis for the Study: Valid and confirmed measurements are a necessary attachment and basis for your Explosion Hazard Study, which every such company must have by law.
- Coverage with the insurance company: In the event of a worst-case scenario (accident or fire), the insurance company will require irrefutable proof of regularly maintained and measured Ex equipment. Without these papers, you risk total loss of insurance coverage and criminal liability.
