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 ready for inspection. No clause creates the role: it is an internal assignment carrying duties that the Gefahrstoffverordnung (GefStoffV, the German hazardous substances ordinance) and the Betriebssicherheitsverordnung (BetrSichV, the German industrial safety ordinance) place on the employer.
The core obligation is the explosion protection document under Section 6 paragraph 9 GefStoffV, produced as part of the risk assessment documentation under Section 6 paragraph 1 and paragraph 8 GefStoffV. It records where explosive atmospheres can form, states whether and which areas were zoned, and sets the technical and organisational measures that follow. The zone definitions are legal text in Annex I Number 1.7 GefStoffV, while TRGS 720, 721 and 722 supply the method. Number 6 of that paragraph also requires the document to name the explosion protection inspections due under Annex 2 Section 3 BetrSichV.
Who carries out those inspections is fixed by law. Installations in hazardous areas are named in Annex 2 BetrSichV and are therefore installations requiring monitoring under Section 2 paragraph 13 BetrSichV, so Sections 15 and 16 apply, not the Section 14 regime for other work equipment. Section 15 paragraph 3 BetrSichV makes an approved inspection body (zugelassene Überwachungsstelle, ZÜS) the inspector by default and admits a competent person only where Annex 2 provides for it. Annex 2 Section 3 numbers 4.1 and 5.1 do provide for it, except under Section 18 paragraph 1 sentence 1 numbers 3 to 7: gas filling installations, stores of more than 10,000 litres of flammable liquids, filling points, filling stations and aircraft fuelling installations. There the inspection before commissioning and the recurring inspection stay with the ZÜS.
The officer schedules and evidences those inspections but does not decide who may sign them. Where a competent person is admitted, the qualification comes from Annex 2 Section 3 numbers 3.1 to 3.3 BetrSichV. Day to day the role ties explosion protection to work clearance: hot work, maintenance and cleaning in zoned areas run on permits and ignition-source management, and Section 15 GefStoffV draws contractors into the same rules. What fails an audit is rarely the document but the evidence chain: a zone plan that never followed a rebuild, equipment of the wrong category, an inspection signed by a body not admitted for it.
Core duties of the Explosion Protection Officer
- Prepare and maintain the explosion protection document under Section 6 paragraph 9 GefStoffV, including the underlying risk assessment.
- Classify hazardous areas into zones per Annex I Number 1.7 GefStoffV with 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 the inspections under Sections 15 and 16 with Annex 2 Section 3 BetrSichV, engaging an approved inspection body wherever Annex 2 reserves the inspection to one and evidencing competence under numbers 3.1 to 3.3 where it does not.
- 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 6 GefStoffV the operator must assess the explosion risk and set it out in the explosion protection document under Section 6 paragraph 9 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, the inspections of Annex 2 Section 3 BetrSichV and ignition-source management, and almost always names a responsible officer to carry them. Competence for the role follows the general standard of Section 2 paragraph 16 GefStoffV: training or experience matched to the task and kept current. Who inspects is a separate question. Under Section 15 paragraph 3 and Section 16 paragraph 4 BetrSichV the inspections belong to an approved inspection body unless Annex 2 Section 3 BetrSichV admits a competent person, and that person must then meet its numbers 3.1 to 3.3.
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, and it does not make the officer the inspector.
- Presence of zone 0/1/2 gas or vapour atmospheres on site

- 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. The inspections under Sections 15 and 16 with Annex 2 Section 3 BetrSichV, the engagement of an approved inspection body where Annex 2 reserves the inspection to one, 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, the zone classification 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.
