External Hazardous Substances Officer: Obligation, Tasks and Appointment Process

Section 6 of the Hazardous Substances Ordinance (GefStoffV) obliges employers to carry out a risk assessment and determine the necessary protective measures before any activity involving hazardous substances. The standard does not prescribe a specific officer title, but does require demonstrably competent persons, written documentation and a functioning hazardous substance management system. Many companies meet this requirement by appointing a hazardous substances officer (GSB), as this role consolidates the entire mandatory regulatory programme: TRGS 400, TRGS 510, safety data sheet management and statutory reporting obligations.

For companies without sufficiently qualified in-house personnel, the external appointment of a hazardous substances officer is the appropriate response to this mandatory situation. This article explains the applicable qualification requirements, how the external appointment is documented in a legally compliant manner, which tasks the GSB assumes within the company, and how CIVAC maps the entire process — from appointment to ongoing documentation — in one workspace.

The Hazardous Substances Ordinance (GefStoffV) of 26 November 2010 in its current version constitutes the primary legal framework. Section 6 GefStoffV obliges the employer to carry out a risk assessment before commencing any activity involving hazardous substances. Substitution testing (Section 7 GefStoffV), protective measures (Sections 8–11 GefStoffV) and training (Section 14 GefStoffV) must be demonstrably implemented.

The Technical Rules for Hazardous Substances (TRGS) specify these obligations in detail: TRGS 400 describes the procedure for hazard assessment, TRGS 402 governs exposure assessment for inhalation exposure, and TRGS 510 defines storage requirements. Where employers breach these obligations, Section 130 OWiG applies: any business owner or senior employee who violates supervisory obligations that enabled a violation to occur is liable for fines of up to €1 million — regardless of who directly committed the administrative offence.

The legislature does not prescribe a specific officer title, but does require demonstrably competent persons. In practice, companies close this gap by appointing a hazardous substances officer (GSB), who consolidates all regulatory requirements into a single documented function. A well-maintained officer file — containing the order document, task list, proof of qualifications and records — significantly reduces the liability risk for management.

For the ongoing maintenance of these documents, a structured workspace that automatically aggregates deadlines, audit results and training records is recommended.

The GefStoffV does not specify a formal job title for the hazardous substances officer. It requires expertise demonstrable through education, professional experience or specific training. In practice, the requirement profile derives from the TRGS themselves and from the recommendations of the professional associations.

A qualified GSB should be able to demonstrate the following knowledge: fundamentals of hazardous substance labelling under the CLP Regulation (EC) No. 1272/2008; hazard assessment procedures under TRGS 400 and TRGS 402; storage and disposal requirements under TRGS 510 and TRGS 520; creation and maintenance of hazardous substance registers under Section 6(12) GefStoffV; and statutory reporting obligations to the Federal Environment Agency and the competent occupational safety authorities.

For external service providers, the commissioning must also be governed contractually. The contract sets out the scope of responsibility, reporting obligations and access to resources. An order document recording the scope of tasks and authorities is mandatory. Without this document, it cannot be demonstrated in an audit that the appointment was formally completed.

CIVAC ensures that all representatives appointed through the platform meet the qualification requirements of the relevant TRGS and that their credentials are stored in the CIVAC workspace.

The hazardous substances officer is not a purely advisory role. They assume operational responsibility in four core areas, which must be evidenced by documentation:

• Risk assessment: Creating and regularly updating the risk assessment under TRGS 400 for all workplaces exposed to hazardous substances. This includes exposure determination, assessment of protective measures and substitution testing under Section 7 GefStoffV.
• Hazardous substance register: Maintaining and updating the hazardous substance register under Section 6(12) GefStoffV, including management of current safety data sheets under Article 31 of the REACH Regulation (EC) No. 1907/2006.
• Training: Conducting and recording annual training sessions under Section 14 GefStoffV for all employees handling hazardous substances.
• Communication with authorities: Acting as contact point for supervisory authorities and professional associations; preparing and accompanying inspections; initiating action plans following official objections.

Externally appointed GSBs carry out these tasks according to an agreed schedule. The schedule and all services delivered must be recorded in the officer log. This is where the external hazardous substances officer via CIVAC comes in: the platform provides templates, record masks and an audit-proof task log that can be exported at any time.

The appointment of a hazardous substances officer is a legal act that must be carried out in writing. Verbal agreements or internal emails are insufficient in an audit. A legally compliant appointment comprises at least five elements:

1. Order document: A written document with the complete role description, task description, authorities, and the signatures of both the representative and management.
2. Proof of qualifications: Evidence that the representative meets the substantive requirements of the GefStoffV and relevant TRGS.
3. Reporting line: Specification of to whom the representative reports, how escalation paths are structured and the frequency of reporting.
4. Resource commitment: Documentation of the resources made available (time, budget, access) to enable the representative to fulfil their obligations in practice.
5. Filing documentation: Secure storage of all documents in a system immediately accessible at the moment of an audit.

According to experience, conventional appointments take two to six weeks, because contract negotiations, qualification checks and document filing proceed sequentially. CIVAC achieves an SLA of two working days: the contract, person and order document are all in place within this timeframe. Order document, signed, filed, verifiable.

In the German regulatory environment, there are two officer types that share the term relating to hazardous substances but have different legal bases: the hazardous substances officer under GefStoffV and the dangerous goods officer under the Dangerous Goods Officers Ordinance (GbV).

The hazardous substances officer under GefStoffV is focused on occupational safety and chemical safety within the company. Their tasks concern the storage, handling and disposal of dangerous chemicals as well as the instruction of employees. The legal bases are the GefStoffV, the TRGS and the CLP Regulation.

The dangerous goods officer under Section 3 GbV focuses on the transport of dangerous goods. They monitor compliance with the regulations under the ADR (road), IMDG (sea), RID (rail) and IATA-DGR (air). Confusing these roles leads to compliance gaps, because transport law obligations and company occupational health and safety obligations require different officers and different documentation.

Companies that both store and transport hazardous substances require both functions. CIVAC maps both roles in one workspace: the hazardous substances officer and the dangerous goods officer, each with their own order document, their own task log and role-specific audit templates.

The question of whether a hazardous substances officer should be trained internally or appointed externally is primarily a question of resources. Internal appointments require an employee to acquire the necessary expertise, receive regular further training and have sufficient time for officer duties alongside their core activities.

Typical cost items for an internal appointment include: a basic course with final examination (€500–€900, one to two days), annual further training (€200–€400), working time for risk assessments, training sessions and documentation (four to eight hours per month depending on company size), and costs for specialist literature, TRGS subscriptions and templates.

External appointment via CIVAC, by contrast, includes all services in one package: a qualified representative, an order document, workspace access for the company, ongoing documentation and 37 ready-to-use audit templates. Total costs are predictable, internal personnel costs are largely eliminated, and the qualification risk rests with the service provider.

Important: even where the appointment is made externally, management remains organisationally responsible. External appointment does not relieve the obligation to grant the representative the necessary resources and access, as required by Section 14(1) GefStoffV.

Technical Rule for Hazardous Substances 400 (TRGS 400) describes the methodological approach to risk assessment as a core requirement of the GefStoffV. It structures the process into seven steps: determining the scope of assessment; identifying and evaluating the hazardous substances; determining the activities to be assessed; determining and evaluating the hazards; substitution testing under Section 7 GefStoffV; defining and implementing protective measures; and effectiveness testing and documentation.

Documentation is not an optional step. Section 6(8) GefStoffV requires that the result of the risk assessment be recorded in writing. This is unconditionally mandatory for companies with more than ten employees. For smaller companies, the obligation applies where activities involve category 1A or 1B hazardous substances under the CLP Regulation, or where the activities require a specific assessment.

In practice, audits frequently fail not because of a lack of protective measures but because of missing or outdated documentation. TRGS 400 provides that the risk assessment must be updated when working conditions, substances used or the state of the art change. A hazardous substances officer who consistently fulfils this update obligation creates the structural conditions for audit resilience.

The CIVAC workspace contains a pre-structured TRGS 400 template that follows the seven steps of the standard and covers all mandatory fields. Audit-proof, documented, Section 6 GefStoffV-compliant.

The hazardous substances officer does not work in isolation. In company occupational safety, there are systematic interfaces with other officer roles that are relevant to the completeness of compliance.

Occupational safety specialist (SiFa): The SiFa under Section 5 ASiG and DGUV V2 is responsible for general occupational safety advice to management. The GSB complements the SiFa on specific hazardous substance matters. Both roles are legally distinct from each other and cannot readily be combined in one person.

Company doctor (BA): The company doctor under Section 3 ASiG and DGUV V2 is responsible for occupational health care. For activities involving category 1A/1B hazardous substances (carcinogenic, mutagenic), mandatory health surveillance is required under the Ordinance on Occupational Health Care (ArbMedVV). The GSB provides the basis for the occupational health assessment by the company doctor.

Environmental officer (UsB): Hazardous substances frequently fall within several regulatory areas simultaneously: occupational safety (GefStoffV), waste law (KrWG, AbfBeauftrV) and water protection (WHG, AwSV). The environmental officer handles the interface with environmental law; the GSB handles that of occupational safety.

CIVAC maps all three roles in one workspace, with clearly separated audit logs and order documents, but with shared documentation storage for areas of overlap.

CIVAC is a German compliance platform and officer-as-a-service solution for SMEs. For the role of hazardous substances officer, CIVAC offers two options: licence the workspace for your internal representatives, or have our representatives assume the function.

In the service model, CIVAC provides a qualified external hazardous substances officer who is formally appointed; the order document and proof of qualifications are available within two working days. The representative works in the CIVAC workspace, which contains all TRGS 400 templates, a structured hazardous substance register, training records and a complete audit log. Instead of the conventional two to six week lead time, companies have a documented, audit-proof officer structure in place within just a few days.

In the workspace model, internal employees gain access to the platform: 37 ready-to-use audit templates, an AI assistant with standard citations, complete documentation and an export report for authorities and auditors. Both models are not mutually exclusive; a mixed structure that relieves an internal GSB through an external one can be replicated in CIVAC without technical complexity.
