If a machine can be locked, it must be. However, there are situations where energy isolating devices can not
accommodate locks. In these cases, the energy isolating devices must be tagged to warn employees that the machine is
de-energized for servicing. The tag must be securely fastened, it must be placed in a position visible to all and it may only
be removed by the person who attached it.
