What is the primary function of safeguarding devices on machinery?

The primary function of safeguarding devices on machinery is to detect operator contact with the machine's point of operation. These devices are essential for ensuring the safety of workers by preventing accidental injury while the machinery is in operation. They can include features such as light curtains, safety mats, or presence-sensing devices that identify when a person's body or limb is in a dangerous zone.

When these devices detect that an operator is too close, they can trigger automatic safety mechanisms that either stop the machine or prevent it from operating until it is safe to resume. This proactive approach significantly reduces the risk of accidents and enhances overall workplace safety.

Thus, the safeguarding devices are critical in creating a safe working environment, focusing specifically on monitoring and protecting against operator exposure to hazards.
