This assessment should identify potential hazards associated with each operating mode and determine the necessary safety measures. The risk assessment should consider factors such as the machine's intended use, the skills and training of the operators, and the potential for human error.

• Identifying Hazards: The risk assessment should identify all potential hazards associated with each operating mode. This includes hazards such as unexpected machine movements, exposure to hazardous substances, and the risk of entanglement or crushing.
• Evaluating Risks: Once the hazards have been identified, the risk assessment should evaluate the likelihood and severity of each hazard. This will help prioritize the implementation of safety measures.
• Implementing Safety Measures: Based on the risk assessment, appropriate safety measures should be implemented to mitigate the identified hazards. This may include measures such as machine guarding, interlocks, and emergency stop devices.
• Regular Review: The risk assessment should be reviewed regularly to ensure that it remains up-to-date and reflects any changes in the machine's operating conditions.

3. Training and Qualification

Operators must be adequately trained and qualified to operate machines with Betriebsartenwahlschalter. Training should cover the function of the switch, the different operating modes, the associated hazards, and the necessary safety precautions. Operators should also be trained on how to perform basic maintenance tasks and how to respond to emergencies.

• Comprehensive Training: Training should be comprehensive and cover all aspects of the machine's operation, including the function of the Betriebsartenwahlschalter, the different operating modes, the associated hazards, and the necessary safety precautions.
