Hazardous substances officer: appointment, tasks, liability and duties 2026

The Hazardous Substances Ordinance (GefStoffV) and the Technical Rules for Hazardous Substances (TRGS), in particular TRGS 400 for risk assessment and TRGS 555 for operating instructions, oblige employers to deal with hazardous substances in the workplace in a structured manner. Section 13 of the Occupational Safety Act (ASiG) and DGUV Regulation 2 specify the organisational responsibility of management. Although it is not legally mandatory to appoint a hazardous substances officer in all companies, in practice it is indispensable as soon as hazardous substances are stored, used or processed in significant quantities, because the duties of management cannot be fulfilled without an expert body nor can they be verified in the event of damage.

This article organises the legal basis, describes the tasks of a hazardous substances officer, clarifies qualification requirements, liability situation and remuneration issues and shows how the appointment can be made in a formally clean manner. You will find out what documentation the auditor wants to see, how a hazardous substances register is created in accordance with Section 6 Paragraph 12 GefStoffV, when an external representative makes more sense than an internal employee and how a digital workspace transfers the duties into audit-proof routines. CIVAC is a compliance platform and officer-as-a-service that offers exactly this dual solution. The auditor calls, the evidence is ready., is the benchmark of this guideline for operational practice and for decision-makers in medium-sized companies and corporations.

The Hazardous Substances Ordinance (GefStoffV) is the central set of rules for dealing with hazardous substances in Germany. It specifies the Occupational Safety and Health Act and implements European law, in particular the CLP Regulation (EC) No. 1272/2008 on classification and labelling and the REACH Regulation (EC) No. 1907/2006 on registration. The obligations range from the substitution test and the risk assessment according to § 6 GefStoffV to the hierarchy of protective measures, the instruction of employees and occupational health precautions according to ArbMedVV.

The Technical Rules for Hazardous Substances (TRGS) specify the GefStoffV. TRGS 400 describes the risk assessment in detail, TRGS 401 the skin hazard, TRGS 402 the inhalative exposure, TRGS 510 the storage in portable containers, TRGS 555 the operating instructions and TRGS 800 the fire protection. These rules have the effect of presumption: anyone who adheres to them complies with the GefStoffV. Anyone who deviates must prove that the measures taken are equivalent, which is rarely possible in practice and leads to a significant reversal of the burden of proof in the event of damage.

Section 13 of the Occupational Safety Act and DGUV Regulation 2 determine the organisational responsibility of management, including the appointment of representatives for special safety areas. Even if the GefStoffV does not name a “hazardous substances officer” as a separate mandatory figure, Section 13 Para. 1 BetrSichV and TRGS 400 result in the obligation to appoint a qualified person. The Hazardous Substances Officer takes on exactly this task with a clear appointment certificate and reporting line to the management, documented and verifiable to supervisory authorities and professional associations. If the function is not clearly established, there is a risk that, in the event of damage, the entire management will be called upon, without the mitigating effect of a distribution of tasks. It is precisely this gap that the formal order with a task profile closes.

The GefStoffV does not have a rigid employee or quantity threshold for the appointment of a hazardous substances officer. The risk assessment is crucial: As soon as the identified risks require expert control, the order becomes organizationally necessary, regardless of the size of the company. In practice, the order makes sense as soon as substances classified as dangerous are regularly handled, such as acids and alkalis, solvents, carcinogenic substances in categories 1A and 1B, sensitizing substances, substances toxic to reproduction or large quantities of flammable liquids.

Sectors with high exposure to hazardous substances include the chemical industry, pharmaceuticals, electroplating, paint shops, metal processing, construction chemicals, cleaning service providers with industrial cleaning, Hairdressing and cosmetics businesses with professional dyes, workshops, laboratories and shipping companies with hazardous materials warehouses. Even in medium-sized businesses, ordering large quantities of fuel, coolants or cleaning chemicals is appropriate, even if the main production is not chemicals.

Small and very small businesses without significant hazardous substances do not necessarily need an appointed hazardous substances officer, but they still have to fulfil the tasks, usually by the management or the employer personally, supplemented by an occupational safety specialist in accordance with DGUV regulation 2. Anyone who does not regulate this clearly runs the risk of failing to comply with the obligations in the Unable to prove damage. The appointment certificate, signed, filed, verifiable, is also the standard here if the function remains in the management. The assumption of responsibility must be documented in writing and must remain fully verifiable in the event of damage, supplemented by evidence of training and further education from those responsible. A mere verbal assignment does not help in the event of a dispute and regularly leads to the cancellation of the delegation of responsibility by courts and supervisory authorities with full transfer back to the owner of the company, including insurance coverage implications.

The tasks of a hazardous materials officer are divided into five main areas, all of which must be supported by documented routines. Firstly, the creation and maintenance of the list of hazardous substances in accordance with Section 6 Paragraph 12 GefStoffV with information on the substance name, classification according to CLP, storage location, storage quantity and intended use. The register must be updated with every change, especially new substances, changed safety data sheets and substitute substance tests. Secondly, the implementation and updating of the risk assessment in accordance with TRGS 400, at least annually and after every relevant change in the work process, in the materials used or in the protective measures.

Thirdly, the creation of activity-related operating instructions in accordance with TRGS 555, which are displayed in understandable language at the workplace and are part of the annual training for employees. Fourthly, the annual instruction in accordance with Section 14 GefStoffV with documentation of the participants, topics and comprehension check. Fifthly, advising the management on procurement decisions, substitution tests and the hierarchy of protective measures according to the STOP principle (substitution before technology before organisation before personal protection).

In addition, there are the interface functions with the occupational safety specialist, the company doctor, the professional association and the responsible supervisory authority. The hazardous substances officer represents the company during inspections, answers official inquiries and prepares an annual activity report for the management. Others run compliance like a filing cabinet. We run it like software., with clear deadlines and a traceable audit trail. The CIVAC workspace bundles registers, risk assessments, operating instructions and proof of training in one interface with clear deadline control and escalation to management. This removes the recurring obligation from the representative's personal task stack and transfers it to a system-supported routine, which continues to run without loss of data even during replacement, vacation or personnel changes and permanently relieves the burden on management.

The GefStoffV and TRGS 400 require an expert person to prepare the risk assessment. Specialist knowledge is acquired through a combination of vocational training, professional activity and proven further training. There is no uniform “hazardous goods officer certificate” like the hazardous goods officer, but rather a variety of training courses from TÜV, DEKRA, IHK, professional associations and private providers. The training courses typically consist of 16 to 40 teaching units and cover legal bases, classification, risk assessment, operating instructions, storage and occupational health precautions.

Minimum qualification requirements are: completed professional training in a relevant specialist area, at least two years of professional experience in dealing with hazardous substances, proven training in the basics of the GefStoffV and TRGS as well as regular training to update specialist knowledge. Annual training of at least eight teaching units, documented with proof of training, is recommended. Without proof of further training, the specialist knowledge loses its presumption against supervisory authorities.

External hazardous substances officers bring the qualifications and further training with them from the outset, often documented by certificates from recognised bodies and by professional experience across several industries. This reduces the training time, ensures technical topicality and relieves the burden on internal personnel planning. CIVAC provides external hazardous materials officers via the officer-as-a-service model, with full role responsibility, annual training and a clear reporting line to management. Licence the workspace for your internal representatives, or have our representatives order it, depending on size and risk profile. This reduces the risk of illness and failure, which represents a significant compliance lever, especially in small companies, and ensures continuous professional representation, without which an individual representative on vacation or in the event of illness leaves an open flank to supervisory authorities and professional associations, with all the liability consequences.

The hazardous substances register according to Section 6 Paragraph 12 GefStoffV is the central tool of the hazardous substances officer. It must record every hazardous substance used or stored in the company, completely and up to date, and contain at least the following information: substance or product name, classification according to CLP with hazard pictograms and H phrases, manufacturer or supplier, safety data sheet version, storage location and storage class, storage quantity and consumption quantity per year, intended use in the company and the substitution test carried out with date and result.

The register must be updated regularly. Reasons include: new substances in the procurement process, changes to the safety data sheet with relevant new hazard warnings, changed classification according to CLP adjustments by ECHA, substitution decisions, changes in quantities, relocations and decommissioning of individual products. A full revision every six months, supplemented by event-related updates, is recommended. Safety data sheets must be available in the current version and in German, in accordance with Article 31 of the REACH Regulation with Annex II, and can be accessed at the workplace within a few minutes.

Audit security is created through digital, versioned cadastral management with a link to safety data sheets, risk assessments and operating instructions. Pure Excel lists are prone to errors in larger companies and can hardly be handed over when there is a change in personnel. The CIVAC workspace offers a structured cadastral function with automatic SDS versioning, substitution documentation and escalation for expired safety data sheets. Audit-proof, documented, GefStoffV-proof. In this way, the cadastre changes from a static directory to an active control instrument for protective measures and the substitution strategy in the company. The switch to substitute substances is also systematically monitored, documented and linked to the risk assessment, so that the substitution test in accordance with Section 6 GefStoffV remains traceable at all times, including the documented reason why a substitution may not have been technically or economically possible, and with a linked risk reassessment in the following year.

The risk assessment according to TRGS 400 is the methodological heart of hazardous substance management. For each workplace with contact with hazardous substances, it describes the identified hazards, the assessment of the exposure (inhalative, dermal, oral, due to the risk of fire or explosion), the substitution test, the protective measures defined according to the STOP principle, the occupational health precautionary measures according to ArbMedVV and those responsible for implementation. It must be in writing, dated and signed by the expert creator and the management as the responsible employer.

The operating instructions in accordance with TRGS 555 follow from the risk assessment. They must be activity-related, in understandable language and displayed for employees at the workplace. Mandatory content is: substance name, dangers, protective measures, what to do in case of danger, first aid, proper disposal and references to the safety data sheet. A generic operating instruction "for all hazardous substances" is not sufficient and is regularly criticized by supervisory authorities because it neither describes the specific dangers nor the specific protective measures.

The annual instruction according to Section 14 GefStoffV must take place before the start of the activity and at least once a year, with documented participants, topics, date and comprehension check. In the event of changes, event-related additional instruction is mandatory. In the CIVAC workspace, risk assessments, operating instructions and proof of instruction can be automatically linked to one another, so that any change to the risk assessment triggers the operating instructions and the obligation to provide instruction. The deadline runs as soon as it is known, the workspace distributes the tasks to those responsible with clear deadlines and prevents individual tasks from being overlooked. Seasonal workers and newly hired employees also receive their instruction before starting work, documented with an electronic signature and automatic filing in the personnel compliance folder with a retention period of at least five years; ten years is recommended for full audit security in the event of damage.

The storage of hazardous substances is regulated in detail in TRGS 510. It differentiates between storage classes (LGK) for flammable liquids, oxidizing substances, acutely toxic substances, corrosive substances and other categories. The TRGS 510 joint storage matrix shows which substances should be stored separately and which may be stored together, depending on the storage quantity, fire protection concept and structural separation. The maximum storage quantity determines additional obligations such as collection trays, ventilation, fire protection walls and, if necessary, ATEX zones.

Flammable liquids above certain quantities trigger obligations from the Industrial Safety Ordinance (BetrSichV) and the Hazardous Substances Ordinance. Hazardous areas must be identified, divided into zones and described in an explosion protection document in accordance with the ATEX Directive 1999/92/EC. The explosion protection document is part of the risk assessment and must be prepared before starting activities in EX areas. It names the zones, the permitted equipment, the organisational measures, those responsible for monitoring and the recurring test intervals of the protective devices used.

The interface to the fire protection officer and the occupational safety specialist must be regulated organizationally, ideally with joint inspections and integrated documentation. Anyone who stores in several properties benefits from a central workspace solution with multi-location capability that clearly maps storage classes, upper quantity limits and storage rules for each location. CIVAC integrates these functions with the role of the fire protection officer and the occupational safety specialist in one platform, so that there are no gaps between the officers and common documents are only maintained once. The official reporting obligations in the event of excess quantities are also reflected in the platform with clear deadlines and reminders, especially for substances that may fall under the Major Accidents Ordinance or are subject to special approval requirements from the responsible supervisory authorities.

Liability when dealing with hazardous substances is spread over several levels. The employer is legally liable according to Section 22 ArbSchG and Section 21 GefStoffV, with fines of up to 30,000 euros per violation. If employees are intentionally or grossly negligently endangered, there will be criminal consequences in accordance with § 26 ArbSchG and §§ 222, 229 StGB, including imprisonment. The hazardous substances officer is liable within the scope of his appointment and his task profile, with the typical limitation to negligence according to BAG case law on employee liability.

The management cannot relieve itself of responsibility simply by appointing him. Section 130 OWiG provides for a supervisory obligation on the part of the owner, the violation of which can be punished with fines of up to one million euros. In the event of damage, the public prosecutor's office checks whether the appointment was made with a clear task profile, sufficient authority and appropriate resources. Without an appointment certificate, without a documented reporting line and without proof of training, the responsibility remains entirely with the management, with full personal liability.

External hazardous substances officers work within the framework of their service contract, with their own professional liability insurance and clear definition of duties in the contract. This reduces the residual risk for the client, but does not replace the company's duty of supervision. CIVAC operates the officer-as-a-service model with documented professional liability, SLA of two working days, certificate of appointment and quarterly activity report to management. This turns the obligation into a controllable routine with a clear distribution of liability and a comprehensible escalation path. The client has access to all relevant documents at any time without having to open external consultant folders and retains data sovereignty over its own compliance system, even if the service provider later changes or the transition to internal capacities is made.

An appointed hazardous materials officer, a well-maintained register and a current risk assessment are building blocks, not an end product. Compliance only becomes reliable when the building blocks are linked in a system: cadastre, safety data sheets, risk assessment, operating instructions, proof of instruction, occupational health care, warehouse overview and interfaces to occupational safety specialists, company doctors and fire protection officers. Only this system survives unannounced inspections by authorities and creates audit security under real conditions.

CIVAC is a compliance platform and officer-as-a-service that provides this architecture as an integrated module. The workspace contains the appointment certificate, cadastral template, risk assessment templates according to TRGS 400, operating instructions templates according to TRGS 555, instruction matrix with deadline control and the 490 ready-to-use audit templates for authority controls. Optionally, CIVAC takes on the role of external hazardous materials officer with a clear appointment certificate and quarterly activity report to the management. Licence the workspace for your internal representatives, or have our representatives order it.

The next step is a 30-minute inventory: current cadastral maturity level, date of the last risk assessment, warehouse structure, ATEX relevance, location distribution and interfaces to other roles. This results in a concrete proposal with a module mix, ordering option and implementation plan. Turn reading into a mandate.: Write to info@civac.de or use the contact form on civac.de. You will receive a concrete answer within two working days instead of a non-binding advice offer. The appointment certificate, signed, filed, verifiable, is the claim. Anyone who requires additional involvement of the occupational safety specialist or the fire protection officer coordinates the roles via the same workspace with a clear reporting line to management. This creates an integrated system for all representatives without redundant data maintenance and without interface losses between the roles, which also supports location expansion and new production processes.
