Group Lockout/Tagout

In the steps outlined in the previous section, one person should place his or her lock on each piece of an energy-isolating device. There may be occasions when more than one person needs to work on a piece of equipment. When this occurs, each person involved in the service or maintenance will be required to place his or her own lock on the energy-isolating device.

  • A single authorized employee must assume the overall responsibility for the control of hazardous energy for all members of the group while the servicing or maintenance work is in progress.
