What is a group lockout box?

A lockout/tagout system is an important type of safety equipment. Power sources and machines can be very dangerous if they are started while someone is working on them. They need to be completely shut down before workers can begin servicing them. A group lockout/tagout system uses keys to make sure that power sources and equipment are shut down and won't reactivate.

Group lockout boxes are used for multiple workers and keys to single or multiple lockout devices. Keys to lockout devices or equipment disconnect master keys are placed in the group lockout box. Each worker on the crew then places his own personal lock on the box. As each worker's task is completed, he removes his personal lock. When all locks have been removed, an authorized crew leader or supervisor verifies all workers are out of danger before reactivating power supplies or equipment.

Accident prevention tags are used with lockout devices to document the time, date, and contact information regarding each device locked out with the group lockout box. Tag messages include "danger – do not operate," "do not start," and "hands off."
