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.
- Traditional lockout requires 50 locks.
(Each employee places a lock on each energy-isolating device.)
- 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.)
