What is an Explosion Protection Officer?
The Explosion Protection Officer (Explosionsschutzbeauftragte) is the person an operator appoints to keep explosion protection in hazardous areas current, documented and audit-ready. The role sits at the intersection of the Hazardous Substances Ordinance (GefStoffV) and the Industrial Safety Ordinance (BetrSichV), with the practical detail set out in the TRGS 720, 721 and 722 series and the ATEX product and operations framework.
The core obligation is the explosion protection document required under Section 6 GefStoffV (in conjunction with the risk assessment duties of Section 5 GefStoffV). This document records where explosive atmospheres can form, classifies those areas into zones 0, 1 and 2 for gases and 20, 21 and 22 for dusts in line with TRGS 720 and TRGS 721, and sets the technical and organisational measures that follow. TRGS 722 covers the avoidance and limitation of hazardous explosive atmospheres.
Unlike a formally legally mandated officer in every case, the Explosion Protection Officer is most often a delegated function: the operator remains responsible, but appoints a competent person to manage zoning, ignition-source control, equipment selection (categories per Directive 2014/34/EU, the ATEX product directive) and the recurring inspections owed under Section 14 and the Annex 2 inspection regime of BetrSichV.
The officer also bridges to work clearance: hot work, maintenance and cleaning in zoned areas require permits and ignition-source management. Because the field combines chemical, mechanical and electrical ignition risks, the role demands documented competence and continuous updating whenever substances, processes or plant change.
Core duties of the Explosion Protection Officer
- Prepare and maintain the explosion protection document under Section 6 GefStoffV, including the underlying risk assessment.
- Classify hazardous areas into zones per TRGS 720 and TRGS 721 and keep zone plans current.
- Apply TRGS 722 to avoid or limit hazardous explosive atmospheres at source.
- Identify and control the 13 ignition sources of EN 1127-1, including electrostatics, mechanical sparks and hot surfaces.
- Verify that equipment and protective systems match the required category under Directive 2014/34/EU (ATEX).
- Organise recurring inspections of plant in zoned areas per BetrSichV and confirm competent-person qualification.
- Run a hot-work and maintenance permit system for activities in Ex areas.
- Train and instruct staff working in or near hazardous areas on conduct and ignition-source avoidance.
- Review the Ex-document on substance, process or plant changes and after incidents or near-misses.
- Keep inspection records, deviation tracking and corrective actions ready for the supervisory authority.
When is appointment required?
There is no single clause that says every operator must appoint a named Explosion Protection Officer. The duty flows indirectly: under Section 5 and Section 6 GefStoffV the operator must assess explosion risk and produce the explosion protection document before work starts in areas where explosive atmospheres can occur. Where the operator lacks the in-house competence to do this and keep it current, delegation to a competent Explosion Protection Officer is the standard route.
In practice the trigger is the presence of zoned areas. Once a workplace contains zone 0/1/2 (gases, vapours, mists) or zone 20/21/22 (dusts), the operator owes a maintained Ex-document, recurring BetrSichV inspections and ignition-source management, and almost always names a responsible officer to carry them. The competence requirement follows TRBS 1112 and the relevant TRGS, and BetrSichV requires inspections by a befähigte Person (competent person) under TRBS 1203 where applicable.
The appointment should be in writing, define the scope (which plants, which areas), confirm the officer's qualification and grant the authority and resources to act. It does not transfer the operator's legal responsibility, which remains with the employer.
- Presence of zone 0/1/2 gas or vapour atmospheres on site
- Presence of zone 20/21/22 combustible-dust atmospheres
- Storage or processing of flammable liquids, gases or dusts under GefStoffV
- New or modified plant that changes the explosion risk assessment
- Operator lacking in-house competence to maintain the Ex-document
- Authority or insurer requirement following an incident

How CIVAC supports the Explosion Protection role
CIVAC gives the Explosion Protection Officer one structured place to keep the Ex-document, zone plans and inspection evidence audit-ready. Recurring BetrSichV inspections, competent-person checks and hot-work permits become scheduled tasks with owners and due dates, so nothing lapses silently before an authority visit. The documentation pillar stores the explosion protection document, TRGS-based zone classifications and corrective actions as versioned records, while training assignments cover staff working in zoned areas. When a substance, process or plant change triggers a re-assessment, CIVAC creates the follow-up task and links it to the affected document, so the chain from change to updated Ex-document to evidence stays intact and demonstrable.
