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.
  • A multi-hasp lock is required if the energy-isolating device does not have enough places for each employee to place his or her own lock.
  • Each employee must affix his/her personal lockout or tagout device to the group lockout device, group lockbox, or comparable mechanism, before engaging in the servicing and maintenance operation.
  • When the activities involving group lockout or tagout extend into another workshift, or there is a change of authorized employees, the provisions for shift or personnel changes must also be followed.
