Explanation:
When more than one worker is carrying out servicing and/or maintenance work, a Group Lockout/Tagout (LOTO) procedure is required for each machine. The idea of the lockout/tagout is to give individuals personal control over the equipment energy sources. Each individual applies and removes a LOTO device to/from a group lockout device, the group lockbox. While every worker in a group attaches the LOTO to the machine that s(he) is servicing, a single authorized employee must take the overall responsibility to implement, coordinate, and communicate to all affected employees the purpose of energy control procedures.
