As set out in the Safety and Health at Work Act (ArbSchG) and the accident-prevention regulation "Principles of Prevention" (DGUV Regulation 1), all employers are required to conduct a risk assessment - regardless of the number of employees. Section 5 of the Safety and Health at Work Act regulates the employer's duty to identify and assess hazards and sets out potential causes of hazards and subjects of the risk assessment. Section 6 requires employers to document the results of the risk assessment, the OSH measures they have determined, and the outcome of their review. Employers can conduct the risk assessment themselves or assign the task to other persons with professional expertise, such as managers, safety and health specialists or company doctors, although the employer retains responsibility for conducting the risk assessment and implementing the results.
