WAC 296-806-45008. Safeguard power-clamping devices

You must protect the operator from the hazards of thrown material when the clamping device does not have adequate pressure to hold the material. Note: Examples of safeguarding methods include: 1. Interlocks. 2. Retaining covers that contain the workpiece if it falls or flies out from the clamped work-holding device. 3. Visual or audible warnings that are located so they can be seen or heard by the operator in the normal work area, making the operator aware that there is no pressure on the clamp side of the actuator.
