ATEX-compliant work in potentially explosive areas
NT Service GmbH covers all key areas of explosion protection in accordance with ATEX – from risk assessment and training to the ATEX-compliant execution of cleaning and maintenance work.
ATEX work in accordance with TRGS and BGR
ATEX-compliant work in potentially explosive areas with clear procedures and certified protective measures.
Thorough
In accordance with ATEX requirements, we remove flammable residues from tank and silo systems. The aim is to reduce potential ignition sources before further work is carried out.
Controlled
With spark-free equipment and coordinated access procedures, we carry out work under controlled conditions. Dust and ignition risks are systematically minimised.
Sustainable
Inspections and maintenance secure the proper condition of systems. Deviations are identified at an early stage. Operational safety in potentially explosive areas is maintained.
ATEX directives in operational use
ATEX regulates explosion protection for systems, work equipment and activities in potentially explosive areas. The ATEX directives form the legal and technical framework for explosion protection in industrial plants and processes, including ATEX work.
For operators, ATEX means systematically assessing hazards, avoiding ignition sources and implementing suitable protective measures. ATEX work in potentially explosive areas may only be carried out according to clear procedures and in compliance with the applicable technical rules.
Key objectives of explosion protection under ATEX:
– Avoidance of effective ignition sources
– Limitation of explosive atmospheres
– Reduction of potential explosion effects
Explosive substances in silo and tank systems
Explosive substances are solid, liquid or gaseous substances that can form an explosive atmosphere under certain conditions. In silo and tank systems, these mixtures often occur through dust release, evaporation or leaks. For ATEX work, the type and level of hazard depend on the material properties, concentration and potential ignition sources.
Zone 20 to 22
In these zones, an explosive atmosphere is present in the form of dust. Typical explosive substances include:
- Flour
- Wood dust
- Metal dusts
- Isotactic and syndiotactic polymers
- Lignite and hard coal dusts
These substances can become explosive if sufficiently fine and dispersed.
Zone 0 to 2
In zones 0 to 2, explosive atmospheres occur due to gases, vapours or mists. Typical substance groups include:
- flammable and volatile solvents
- chlorinated and aliphatic solvents
The hazard arises particularly in the event of leaks, open processes or insufficient ventilation.
Risk of ATEX zone formation
Potentially explosive zones often arise when handling flammable substances during normal operation or in the event of malfunctions. Typical causes include:
- Cleaning auxiliaries
- Adhesives and coating materials
Temporary activities such as maintenance or cleaning can also lead to the formation of explosive atmospheres.
Frequently Asked Questions
Here we answer common questions about ATEX work, our services, processes and areas of expertise. For further questions, we will be happy to assist you personally – simply use our contact form.
What protective measures are taken during ATEX work?
Our technicians work with equipment suitable for ATEX areas, including antistatic clothing, appropriate protective suits and respiratory protection in line with the respective risk assessment. Depending on the location and substances involved, low-spark tools are used, as required for ATEX work in chemical or tank systems. In more heavily contaminated areas, coordinated respiratory protection concepts are applied to enable safe work under the relevant ambient conditions.
Do you also use abrasive blasting technology in ATEX areas?
Abrasive blasting technology is also used in ATEX areas for selected tasks. This includes, among other things, corrosion removal in tanks or the preparation of surfaces for coatings. The procedures and work equipment used are selected in such a way that additional ignition sources are avoided. Operations are carried out exclusively on the basis of the respective risk assessment and in compliance with the applicable explosion protection requirements.
How do you prevent gases from accumulating during work?
To prevent dangerous gas concentrations, the existing ventilation and exhaust systems of the facility are used and checked for effectiveness. Gas and atmosphere measurements are carried out in accordance with the risk assessment and operational requirements. Work is only performed under approved conditions and is stopped immediately if abnormalities are detected.
What documentation do I receive after completed ATEX work?
After completed ATEX work, we provide traceable documentation of the measures carried out. This includes information on the procedures applied, the protective measures used and relevant approvals under ATEX requirements. The documents serve as a basis for internal records and official inspections, ensuring transparency for the operator.
How can I qualify my employees in the field of ATEX?
Our range of services also includes training courses in which employees are instructed in the fundamentals and safety requirements of the ATEX directives. The aim is to strengthen their understanding of hazards in potentially explosive areas and to teach proper handling during ATEX work and day-to-day operations. The training courses are aimed, among others, at technical personnel in industrial fields such as the chemical industry.
How do you respond in the event of an incident in an ATEX area?
What happens to the explosive substances after cleaning?
In accordance with ATEX requirements, flammable residues from tank and silo cleaning are properly collected and further treated. This applies in particular to chemical residues, which are removed and disposed of in accordance with applicable regulations. The aim is to reduce potential ignition hazards and hand over the system in a safe condition after completion of the work.
