For safety reasons, machine tools used for the machining of metal items must be fitted with robust safety doors, for example to prevent debris being ejected at high velocity in the event of tool failure. Since, in order to provide the required stability, these doors are often very heavy, opening and closing them manually requires a high level of force. For production of one-off items and short production runs, this can become critical when the doors must be opened and closed frequently. Electrical drives for doors can assist the user during these operations.

The Technical Report ISO/TR 22100-3 describes how ergonomic principles can be applied during the risk reduction process according to ISO 12100 and how ergonomics standards can be applied to machinery. It helps designers take decisions with respect to ergonomics during the machine design process and can also be used when no relevant type C standards are available.
