Guide to Working in Hazardous Environments in Germany (2025)
A hazardous work environment is any workplace that contains factors which may cause harm to health or safety, such as heavy machinery, toxic chemicals, or explosion and fire risks (Gesetze im Internet, Arbeitsschutzgesetze).
The Occupational Health and Safety Act (Arbeitsschutzgesetz – ArbSchG) regulates the protection of employees against occupational risks and obliges employers to assess all risk factors and take the necessary preventive measures (Gesetze im Internet).
Before any activity is started in a hazardous environment, the employer must carry out a detailed risk assessment of the workplace (§ 5 ArbSchG). This includes:
Identifying all sources of danger
Determining which employees are exposed
Evaluating the severity and probability of each risk
Developing a protection and action plan for those affected
The findings must be documented and reviewed regularly, especially when the nature of the work changes or new equipment is introduced.
The Ordinance on Industrial Safety and Health (Betriebssicherheitsverordnung – BetrSichV) regulates the safe use of work equipment. All tools and machines must be designed, installed and operated in such a way that workers are not exposed to avoidable hazards (§ 3 BetrSichV) (Gesetze im Internet).
If a tool or machine has hazardous characteristics (e.g. high pressure, extreme temperatures, explosion risk), special inspection intervals must be observed according to the manufacturer’s instructions and the results of the risk assessment. All inspections must be recorded.
The Hazardous Substances Ordinance (Gefahrstoffverordnung – GefStoffV) covers all chemical substances, gases and dusts that may cause harm to health or the environment. The main obligations include:
Substitution: hazardous substances must be replaced by less dangerous alternatives wherever possible.
Storage and labelling: substances must be stored and labelled in accordance with the CLP Regulation (Classification, Labelling and Packaging).
Operating instructions: written operating instructions (Betriebsanweisungen) must be provided in German and in a language understood by the employees (BAuA).
Practical implementation is supported by the Technical Rules for Hazardous Substances (TRGS) issued by the Committee on Hazardous Substances, for example TRGS 555 on operating instructions and training for hazardous substances.
Employers must provide verbal and written instructions (Unterweisungen) covering:
the existing hazards,
protective measures,
and correct behaviour in everyday work and in emergency situations.
Training has to be given when employment starts, whenever there are significant changes to work processes or when new equipment is introduced, and must be repeated regularly (§ 12 ArbSchG) (BfGA, Arbeitsschutz NRW).
Typical content includes:
Access restrictions and special rules for hazardous areas
Proper use of personal protective equipment (PPE)
Emergency procedures and reporting chains (e.g. fire, explosion, chemical release)
If technical (e.g. enclosures, ventilation systems) and organisational measures (e.g. access control, shift planning) are not sufficient on their own, the employer must provide personal protective equipment (PPE) such as:
Helmets
Safety goggles and face shields
Respiratory protection
Safety shoes
Protective clothing and gloves
Employees must be trained in the correct use, cleaning and care of PPE (buzer.de).
PPE is always the last step in the hierarchy of controls:
Eliminate or reduce the hazard technically
Organise the work (e.g. limit exposure time, restrict access)
Use PPE as the final protective layer
All employees working in hazardous environments are covered by statutory accident insurance under SGB VII. The responsible bodies are the Berufsgenossenschaften (professional associations) and accident insurance funds, which are in charge of:
Prevention (inspections, advice, training material)
Benefits after occupational accidents or diseases (treatment, rehabilitation, pensions)
(Industrie- und Handelskammer, Wikipedia).
The employer must register the company with the relevant Berufsgenossenschaft within two weeks of commencing operations (§ 192 SGB VII). Only then is it guaranteed that all employees are insured in case of an accident.
The Ordinance on Occupational Health Care (ArbMedVV) requires employers to appoint an occupational physician (or equally qualified doctor) to conduct regular health examinations for employees exposed to hazardous conditions, such as:
toxic substances
carcinogenic or mutagenic agents
significant noise, heat or radiation
Examinations are typically carried out before starting the job and then at regular intervals (§ 2 ArbMedVV) (Gesetze im Internet).
According to GefStoffV, the occupational physician must be involved early in the risk assessment concerning hazardous substances, so that effective preventive measures can be designed and implemented (§ 7 GefStoffV) (buzer.de).
Non-compliance with the requirements of ArbSchG, BetrSichV or GefStoffV may lead to significant consequences for the employer, including:
Administrative fines of up to €30,000 in certain cases
Criminal liability, including imprisonment, in serious cases with severe consequences (e.g. death or major injury) (§ 25 ArbSchG) (Gesetze im Internet).
If an employee knowingly ignores safety instructions, fails to follow training content or refuses to use PPE despite being obliged to do so, the statutory accident insurance may, in extreme cases, reduce benefits or limit coverage, especially when gross negligence is proven.
Working in a hazardous environment in Germany is governed by a strict legal framework that places numerous obligations on the employer, including:
Risk assessment and documentation
Safe operation of equipment under BetrSichV
Correct handling of hazardous substances under GefStoffV
Regular training and instruction
Provision of suitable PPE
Registration with statutory accident insurance
Occupational health examinations and preventive health measures
For employees, this results in a high level of protection, provided that the rules are respected and followed in everyday practice. Strict compliance with these regulations significantly reduces workplace accidents, occupational diseases and long-term health damage, contributing to a safer and more sustainable working environment.
