Group lockout: Fewer lockout devices required
For complicated energy-control systems, group lockout can reduce the number of
lockout devices that employees must use.
Here is an example: Ten employees do maintenance on a machine that
has five energy sources that need to be isolated.
n Traditional lockout requires 50 locks.
(Each employee places a lock on each energy-isolating device.)
n Group lockout requires 15 locks. (A designated person in the group
places a lock on each of the five energy-isolating devices. Each authorized
employee places his or her own lock on the group lockbox containing the
five keys.)
Group lockout can also reduce the risk of injury for service and
maintenance employees, contractors, and other affected employees who
do not regularly work with complicated energy control systems.
