A new cleaning product in a cupboard, aerosol cans at packing stations or resin in a workshop can each create a documentation duty. If you are asking how to register hazardous chemicals in Germany, the first point is reassuring: this does not usually mean filing every product with an authority. It means creating and maintaining a hazardous substance register that shows what employees may be exposed to, where it is used and how you control the risk.
For employers, this register is not paperwork for its own sake. It is the practical starting point for safe purchasing, employee instruction, storage arrangements and a defensible response when an accident insurance institution asks to see your controls.
What registration means under German law
The Hazardous Substances Ordinance (Gefahrstoffverordnung, GefStoffV) requires employers to identify hazardous substances used in the workplace and to maintain a hazardous substance register (Gefahrstoffverzeichnis). The duty sits alongside your wider risk assessment (Gefährdungsbeurteilung) under the Occupational Health and Safety Act (Arbeitsschutzgesetz, ArbSchG).
In practice, the register is an inventory of substances that can present a health or safety risk to employees. This includes products marked with hazard pictograms, such as flammable solvents, corrosive descalers and toxic adhesives. It can also include substances created by work activities, for example welding fumes, wood dust, diesel exhaust emissions or powder generated during cutting and sanding.
Do not rely only on a product name or a supplier catalogue. The actual work matters. A substance used once a month in a ventilated area presents a different exposure profile from the same substance used all day in a confined production space.
A limited exception may apply where only small quantities are used and the risk is low. However, that conclusion must follow a suitable assessment, not an assumption based on the container size. If there is uncertainty, record the substance and assess it. It is usually easier to remove an unnecessary entry later than to explain a missing one after an incident or inspection.
How to register hazardous chemicals step by step
1. Build a complete workplace inventory
Start with a walk-through of every area where substances are purchased, stored, transferred, used or produced. For an office, this may include cleaning stores, maintenance cupboards and printer supplies. In a warehouse or logistics operation, check battery charging, vehicle maintenance, spill-response materials, aerosols and outsourced cleaning arrangements. Production sites need a wider review of raw materials, lubricants, process chemicals and emissions created during work.
Speak to the people doing the work. Unrecorded products often enter the site through facilities teams, local purchasing, maintenance contractors or staff who bring in a familiar cleaning product from another location. Your inventory should reflect reality, not just central procurement records.
For each entry, obtain the current safety data sheet (Sicherheitsdatenblatt, SDS) from the supplier. The SDS provides the classification, hazardous ingredients, handling measures, personal protective equipment, first-aid information and disposal guidance you need for the next stage.
2. Create the hazardous substance register
The register should be clear enough for a manager, occupational safety specialist (Fachkraft für Arbeitssicherheit, or SiFa) or inspector to understand the substance and locate the supporting information. It does not need to be a complicated software system. A controlled spreadsheet can be suitable for a small site, provided it is kept current and accessible.
For each substance, record the product or substance name, its hazardous classification or relevant hazardous properties, the work area where it is used, and a reference to the current SDS. It is also sensible to note the supplier, internal product code, approximate quantities, typical activity, storage location and date of review. These extra fields make the register operational rather than a static filing exercise.
Use a consistent naming convention. “Cleaner” is too vague when several products are in use. Record the full commercial name, manufacturer and version of the SDS so the entry can be matched to the correct label and control measures.
3. Assess exposure and put controls in place
Registration alone does not make work safe. Each relevant substance and activity must feed into the risk assessment. Consider who is exposed, by which route and for how long. Exposure may occur through inhalation, skin contact, splashes, accidental ingestion or fire and explosion hazards.
The preferred control is usually substitution. Ask whether a less hazardous product, a ready-to-use dilution or a different process can remove or reduce the risk. If substitution is not practicable, use technical and organisational controls before relying on personal protective equipment. Examples include local exhaust ventilation, closed dispensing systems, restricted access, clear storage segregation and written work instructions.
Personal protective equipment has a role, but gloves and masks are not a substitute for poor process design. The SDS may suggest suitable protection, yet the final selection must match the task, duration, concentration and conditions at your workplace.
Keep the register connected to daily operations
A hazardous substance register becomes unreliable when it is treated as a one-off project. Make it part of your purchasing and change process. Before a new chemical arrives on site, request its SDS, check whether a safer alternative is available, decide where it will be stored and update the register and risk assessment where necessary.
Review the register when products change, a supplier issues a revised SDS, a process changes, an incident occurs or employees report symptoms or concerns. A periodic planned review is also sensible, particularly for sites with active maintenance, frequent stock changes or multiple departments buying supplies.
Employees must receive instruction that reflects the actual substances and tasks they encounter. Generic chemical-safety training is rarely enough on its own. Staff need to know the key hazards, safe handling rules, required protective equipment, emergency procedures and where to find relevant information. For workers with limited German, deliver instructions in a language and format they can understand.
Storage also deserves attention. Check that incompatible substances are separated, containers remain labelled, decanted products have suitable workplace labels and access is controlled where needed. Keep emergency equipment proportionate to the substances and foreseeable events, rather than buying a standard kit and assuming the job is done.
When additional duties may apply
Some substances trigger controls beyond the standard register and risk assessment. Carcinogenic, mutagenic or reprotoxic substances may require stricter exposure controls, enhanced documentation and retention of exposure records. Activities involving asbestos, lead, biological agents, explosives or certain precursor chemicals can also bring separate duties.
This is where the answer depends on the substance, the process and the quantity used. The register helps you identify these cases early, but it should not be used as a substitute for competent assessment. An occupational safety specialist can review the work process, while a company doctor (Betriebsarzt) can advise where occupational health precautions or preventive examinations may be relevant.
Authorities and accident insurance institutions may focus on whether your documentation reflects conditions on site. A polished register will not help if unlabelled containers, expired SDS documents or unsuitable storage tell a different story. Conversely, a well-maintained register supported by visible controls gives you a practical basis for correcting issues quickly.
A practical three-step route to compliance
If your business is starting from scratch, take a focused approach. First, inspect the site and collect product and process information. Second, build the register and complete risk assessments for the activities that create exposure. Third, implement controls, train employees and set review responsibilities.
Captain Safety can support this work from the initial site inspection through documentation, corrective actions and ongoing review. This is especially useful when you operate several German sites, have received a deficiency notice or need English-language support to coordinate local teams.
Common questions about hazardous chemical registration
Do we need to register every cleaning product?
Not necessarily, but many professional cleaning products are hazardous substances and should be assessed. Start with the label and SDS, then consider how and where employees use the product. Small quantities may be eligible for a low-risk approach, but only after you have checked the actual conditions of use.
Is an SDS the same as a hazardous substance register?
No. An SDS describes a specific product. The hazardous substance register is your employer-controlled overview of the hazardous substances present at your workplace, with references to the relevant SDS documents. You normally need both.
Who is responsible for the register?
The employer remains responsible, even if practical work is delegated to facilities, operations, procurement or an external specialist. Assign a named person to maintain the register, but ensure managers have the authority and time to obtain information, make changes and stop unsafe use where necessary.
What happens if our register is incomplete?
An incomplete register can lead to gaps in risk assessment, training and emergency planning. It may also become an issue during an inspection or after an accident. The sensible response is to identify the gaps, prioritise higher-risk substances and document the corrective work rather than trying to recreate everything at once.
A good register gives you more than a document for a folder. It gives your people a clearer route from purchase to safe use, and gives you a firm footing when the next product, new site or inspection arrives.
