Major Accident (Störfall): Legal Obligations, Appointed Officer, and Prevention at a Glance

The 12th Federal Immission Control Ordinance (12. BImSchV), known as the Major Accident Ordinance (Störfallverordnung), requires operators of upper-tier establishments to appoint a Major Accident Officer (Störfallbeauftragter) under § 58a BImSchG, and to implement comprehensive prevention and emergency measures. The background is the European Seveso III Directive (2012/18/EU), developed following the chemical accident in Seveso in 1976 and transposed into German law in 2015.

This article explains which businesses fall within the scope of the ordinance, which tasks are assigned to the Major Accident Officer by statute, what the notification and documentation obligations look like, and what organisational structures the supervisory authorities expect during an inspection. It also explains how an external Major Accident Officer can fulfil the requirements and what additional benefit a structured compliance workspace provides.

The 12th Federal Immission Control Ordinance (12. BImSchV) applies to establishments in which dangerous substances are present or may be present in quantities that meet or exceed the threshold quantities in Annex I of the ordinance. The ordinance distinguishes two tiers: lower-tier establishments (column 4) and upper-tier establishments (column 5). The upper tier is subject to stricter requirements, including the obligation to produce a safety report and to implement internal emergency plans.

Relevant substance groups include ammonia, chlorine, ethylene oxide, liquefied petroleum gas, and a broad range of explosives and toxins. Storage quantities of heating oil or diesel can also fall within scope from certain threshold values. Whether a business is affected is determined by the summation rule under Annex I, paragraph 4: where multiple substances are present in a single establishment, their hazard potential is added proportionally.

Operators are required to document the results of this assessment and to notify the competent authority under the notification obligation (§ 7 of the 12th Federal Immission Control Ordinance (12. BImSchV)). A missing or incorrect notification constitutes a regulatory offence. Those uncertain about classification may consult the enforcement guidance of the Joint Federal-State Working Group on Immission Control (LAI).

For the Major Accident Officer, the correct classification of the establishment is the first step in the audit workflow: without a valid threshold quantity assessment, the safety report cannot be reliably prepared.

§ 58a(1) BImSchG requires operators of upper-tier establishments to appoint one or more Major Accident Officers. The appointment must be made in writing, must define the specific area of responsibility, and must be notified to the competent authority without delay. A merely internal designation without notification to the authority does not fulfil the statutory requirement.

The requirements for the person of the Major Accident Officer are governed by § 58b BImSchG: they must possess the required expertise and reliability. Expertise generally presupposes a natural science or engineering qualification with relevant work experience and specific training on the Major Accident Ordinance. Reliability means the absence of relevant criminal convictions and a willingness to fulfil obligations independently.

The independence of the officer in the exercise of their duties is important: the Major Accident Officer must not be disadvantaged for performing their tasks (§ 58d BImSchG, analogous to the data protection officer under Art. 38 GDPR). Violations of the protection against disadvantage can give rise to claims for damages. Lower-tier establishments are exempt from the appointment obligation under § 58a BImSchG but must produce and implement a major accident prevention policy (KVSU).

Letter of appointment: signed, filed, demonstrable. This applies equally to the Major Accident Officer: a form in a drawer does not satisfy the supervisory authority.

§ 58c BImSchG sets out the statutory task catalogue for the Major Accident Officer. This is more extensive than for many other officer roles: the Major Accident Officer works towards the development and introduction of environmentally and safety-friendly processes, monitors compliance with the provisions on the prevention of major accidents and the limitation of their consequences, and reviews safety reports for currency and completeness.

In addition, they are obliged to inform employees of possible hazards and protective measures and to conduct regular training sessions. They participate in the preparation of internal emergency plans and check their effectiveness following exercises or real events. They are also required to report to senior management without delay any deficiencies that could constitute a hazard.

The performance of tasks must be documented. Authorities require evidence during inspections under § 16 of the 12th Federal Immission Control Ordinance (12. BImSchV) of activities carried out, training records, deficiency reports, and their resolution. Incomplete documentation results in compliance orders or fines under § 62 BImSchG in conjunction with the 12th Federal Immission Control Ordinance (12. BImSchV).

The CIVAC platform provides the Major Accident Officer with structured task templates, audit checklists, and an automated documentation workflow. More on the task profile can be found on the page for the external Major Accident Officer at CIVAC.

Upper-tier establishments are required under § 9 of the 12th Federal Immission Control Ordinance (12. BImSchV) to produce a safety report. This must be in place before commissioning, but at the latest at the time of first storage of dangerous substances above the threshold quantities. The safety report must be submitted to the competent authority and updated upon material changes to the establishment.

In terms of content, the safety report in accordance with Annex II of the 12th Federal Immission Control Ordinance (12. BImSchV) must cover: general information about the company and the establishment, a description of the safety management system (SMS), a hazard analysis identifying all relevant scenarios, a description of prevention and emergency measures, and a description of the surrounding land use and the potential impact areas of a major accident.

The obligation to update applies in particular to changes in processes, substances, quantities, or operational organisation. The report must also be revised following an actual major accident, incorporating the lessons learned. The authority may at any time require review or supplementation of the report.

An incomplete or outdated safety report is treated in practice as a material deficiency. The Major Accident Officer bears shared professional responsibility for the currency of the document; they must be able to demonstrate this. Audit-ready, documented, and compliant with § 9 of the 12th Federal Immission Control Ordinance (12. BImSchV): this evidence is provided more reliably by a structured workspace than by a manually maintained directory of files.

When a major accident occurs, several notification obligations are triggered simultaneously. Under § 19 of the 12th Federal Immission Control Ordinance (12. BImSchV), the operator is required to notify the competent authority without delay. The authority forwards the information to the Federal Office of Civil Protection and Disaster Assistance (BBK) and via the European eMARS system to the European Commission.

Additionally, a notification obligation may arise under § 16e ChemG if dangerous substances are released and personal injury has occurred or is to be feared. In the case of water pollution, the water authorities must be informed under § 32 WHG. If the major accident overlaps with a data protection incident, Art. 33 GDPR applies, with the 72-hour deadline to the data protection supervisory authority. The deadline runs from the point of knowledge.

The operator must, under § 19(2) of the 12th Federal Immission Control Ordinance (12. BImSchV), produce a follow-up report within a reasonable period documenting causes, measures taken, and conclusions for the future. This follow-up report feeds into the update of the safety report.

The Major Accident Officer coordinates the notification internally and ensures that deadlines are met and all relevant authorities informed. Notification route templates and deadline tracking are stored in the CIVAC workspace so that in the event of an incident no time is lost searching for the right forms.

The 12th Federal Immission Control Ordinance (12. BImSchV) requires upper-tier establishments to have two planning documents: the internal emergency plan (§ 10) and the external emergency plan (§ 11), which is prepared by the competent authority but based on the operator's information. The internal emergency plan governs how the establishment responds internally in the event of an incident: alert chains, responsibilities, evacuation measures, initial response measures, and communication with external parties.

The external emergency plan is prepared by the competent authority in collaboration with the fire service, emergency services, and the BBK. The operator is obliged to cooperate and must provide all necessary information to the authority. Both plans must be reviewed at least every three years and updated immediately upon material changes.

Regular emergency exercises are mandatory. In accordance with the requirements of the 12th Federal Immission Control Ordinance (12. BImSchV), internal emergency exercises must take place at least every three years; the external exercise involving the fire service must be carried out at least every three years. Exercises must be documented, and lessons learned must be incorporated into the update of the plans.

The Major Accident Officer coordinates exercise planning and evaluation. Those who underestimate this effort risk compliance orders during the authority inspection under § 16 of the 12th Federal Immission Control Ordinance (12. BImSchV). For comparable emergency planning under ISO 22301, CIVAC also offers the Emergency Officer as an external role.

§ 16 of the 12th Federal Immission Control Ordinance (12. BImSchV) requires the competent authority to conduct regular inspections. Upper-tier establishments must be inspected at least once annually; lower-tier establishments at least every three years. The authority may also conduct unannounced inspections on a cause-related basis, for example following complaints from neighbours or after a near-miss incident.

The subject of the inspection includes: the completeness and currency of the safety report, the safety management system, implementation of the internal emergency plans, the conduct of training and exercises, and documentation of the Major Accident Officer's activities. The authority may request documents and inspect parts of the establishment.

Deficiencies identified during the inspection are documented in an inspection report and served on the operator. Material deficiencies result in compliance orders; serious violations may lead to fines under § 62 BImSchG. In extreme cases, the authority is empowered to partially or completely prohibit operations.

The inspector calls, the evidence is ready. This principle applies to the major accident domain with particular force: inspections can be announced at short notice or conducted entirely unannounced. Businesses that store all documents digitally, in a structured manner, and with timestamps pass inspections considerably more smoothly than those who must first search for their files.

BImSchG does not preclude the appointment of an external Major Accident Officer. The relevant administrative provisions and the LAI enforcement guidance recognise external officers, provided that expertise and reliability are individually demonstrated and the external person is available to the establishment to a sufficient extent. In practice, this means: contractual response times, defined availability in the event of an incident, and a clear reporting line to senior management.

The selection of the external officer should be based on objective criteria: references in comparable establishments, evidence of relevant continuing education, knowledge of the current LAI enforcement guidance, and the ability to independently prepare or update safety reports and emergency plans.

Liability matters must be governed contractually: the external Major Accident Officer is liable for obligations they have assumed; the operator remains liable for organisational integration and provision of the necessary resources. A clear service contract with a task catalogue, reporting obligations, and liability clauses protects both parties.

CIVAC enables the appointment of a qualified external Major Accident Officer through the Officer-as-a-Service model. Licence the workspace for your internal officers or appoint our officers. Both routes run through the same workspace, the same audit log, the same evidence base.

Those wishing to check whether their establishment falls within the scope of the 12th Federal Immission Control Ordinance (12. BImSchV) begin with the threshold quantity assessment under Annex I. The result of this assessment must be documented, regardless of whether the thresholds are reached or not. If the establishment falls into the lower or upper tier, the further obligations follow in a clearly defined sequence: major accident prevention policy or safety report, appointment of the officer, notification to the authority, internal emergency planning, training, exercises.

Mid-sized businesses that neither employ nor wish to employ their own qualified Major Accident Officer may fill the function externally. The external officer requires a structured workspace to manage deadlines, documents, and reporting obligations reliably. A filing folder solution no longer meets the requirements for audit readiness and traceability.

CIVAC is a compliance platform and Officer-as-a-Service that equips the Major Accident Officer with 490 ready-to-use audit templates, structured training modules, and a seamless documentation workflow. Appointment is completed with a letter within two working days. All data remain within the EU.
