Does the BetrSichV also require an explosion protection document?

No. The document is required by § 6(9) GefStoffV. The BetrSichV refers to the zones for the selection and inspection of work equipment.

Does this distinction exist outside Germany?

The EU basis is Directive 1999/92/EC; each member state transposes it in its own law. The split between equipment use and hazardous substances is German.

BetrSichV or GefStoffV: which ordinance carries the duty?

Does the duty to keep the explosion protection document current come from the BetrSichV or the GefStoffV?

Review log and changes

The short answer

From the GefStoffV. The explosion protection document is part of the risk assessment under § 6 of the Ordinance on Hazardous Substances, which also requires its prompt update after significant changes. The BetrSichV governs the use and inspection of work equipment, including Ex equipment, and has its own review duty in § 3(7). The result is often the same; the legal basis is different.

For: Occupational safety specialists, plant operators, auditors and authors of compliance documentation

Key points

GefStoffV § 6: risk assessment of hazardous substances, explosion protection document (para. 9), prompt update (para. 10).
BetrSichV § 3(7): regular review of the risk assessment of work equipment, taking the state of the art into account.
Both ordinances lead to the same practical result: keep the assessment current after every conversion.
Attributing the duty to the wrong ordinance weakens any argument built on it.
Technical Rules (TRBS, TRGS) carry a presumption effect; recommendations such as EmpfBS 1114 do not.

The context

Two ordinances, two subjects

The BetrSichV is about work equipment: its provision, use, maintenance and inspection. The GefStoffV is about activities with hazardous substances, including fire and explosion hazards. The explosion protection document belongs to the second.

Where they meet

Ex equipment is work equipment, so its inspections follow the BetrSichV. The zone classification, the explosion protection concept and the duty to update the document follow the GefStoffV. A conversion therefore usually touches both: the risk assessment of the equipment and the explosion protection document.

Why the distinction matters

In discussions about grandfathering the duty is often attributed to the wrong ordinance. The result may not change, but the citation does, and an argument with the wrong legal basis is easy to dismiss. The same care applies to the weight of a source: a Technical Rule carries a presumption effect, a recommendation such as EmpfBS 1114 does not.

Glossary terms on this card

Ordinance on Industrial Safety and Health (BetrSichV)
The German Ordinance on Industrial Safety and Health (Betriebssicherheitsverordnung, BetrSichV) sets the employer's duties for providing and using work equipment, including machinery and installations requiring monitoring: risk assessment, protective measures, inspections and maintenance throughout the period of use.
Ordinance on Hazardous Substances (GefStoffV)
The German Ordinance on Hazardous Substances (Gefahrstoffverordnung, GefStoffV) sets the employer's duties for activities involving hazardous substances, including the risk assessment of fire and explosion hazards, the classification of hazardous areas into zones and the explosion protection document.
Explosion protection document
Under Directive 1999/92/EC and, in Germany, § 6(9) of the Ordinance on Hazardous Substances (GefStoffV), the explosion protection document is the part of the employer's documented risk assessment that shows the hazards from explosive atmospheres separately: how they were identified and assessed, the explosion protection concept, the zones and the measures and inspections that apply. It must be kept up to date.
Presumption effect (technical rules)
In German occupational safety law, the presumption effect is the legal effect by which an employer who complies with the technical rules published by the responsible committee, such as the Technical Rules for Operational Safety (TRBS) under § 4(3) BetrSichV, may assume that the corresponding requirements of the ordinance are met. Other solutions are possible if they achieve at least the same level of safety and health.
Adaptation to the state of the art (work equipment)
In German operational safety law, adaptation to the state of the art is the employer's duty to keep work equipment safe to use by the current state of the art throughout its period of use. EmpfBS 1114 distinguishes the state of the art at placing on the market, which governs the design of a product, from the state of the art in use, which governs the protective measures of the employer.
Grandfathering (work equipment)
In German occupational safety law, grandfathering (Bestandsschutz) is the common but misleading idea that a plant or machine may keep operating unchanged because it complied with the rules when it was put into service. The Ordinance on Industrial Safety and Health (BetrSichV) grants no general grandfathering for work equipment: the employer must review the risk assessment regularly, considering the state of the art.
