Consult your facility procedure. Each facility should have a written lockout/tag out program and
train employees in this program. The typical program should cover planning for locating and
labeling energy sources, identifying employees at risk, how and by whom the equipment is de-
energized, releasing of stored energy, verifying that the circuit is de-energized and can't be
restarted, voltage testing, grounding requirements, shift changes, coordination with other jobs in
progress, a procedure for keeping track of all involved personnel, applying and removing
lockout/tag out devices, return to service, and temporary re-energizing for testing/positioning.
Lockout/tag out procedures should be developed for each machine or piece of equipment that
will require servicing.

Lockout / Tag out Application

Each person who could be exposed to electric energy must be involved in the lockout/tag out
process. A typical process is described below.



After de-energizing, each employee at risk should apply an individual lockout/tag out
device to each source of electric energy. Pushbuttons or selector switches cannot be used
as the only way to de-energize.



A lockout device is a key or combination lock with a tag that can be attached to a
disconnecting device to prevent the re-energizing of the equipment being worked on
without removal of the lock. The lockout device should have a way of identifying the
individual who tagged it and the reason why it was tagged. Individual lockout devices
with worker’s name and picture on them are preferred. That worker must be the only
person who has the key or combination for the lockout device they install, and that
worker should be the only person to remove the lock after all work has been completed.



A tag out device is a tag and a way to attach it that can withstand at least 50 pounds of
force. Tagout devices should be used alone only when it is not possible to install a
lockout device.



The tag used in conjunction with a lockout or tag out device must have a label prohibiting
unauthorized disconnecting or removal of the lockout/tag out device.



Before beginning work, each involved worker must verify through testing that all energy
sources have been de-energized.



Electric lockout/tag out procedures should be coordinated with all other site procedures
for controlling exposure to electric energy and other types of energy sources.



Complex lockout/tag out procedures are special procedures that are needed when there is
more than one energy source, crew, craft, location, employer, way to disconnect, or
lockout/tag out procedure or for work that lasts beyond one shift. In any of these cases,
one qualified person should be in charge of the lockout/tag out procedure with full
responsibility for ensuring all energy sources are under lockout/tag out and to account for
all people on the job.



Removal of lockout/tag out devices. Lockout and tag out devices should be removed only
by the person installing them. If work is not completed when the shift changes, workers
arriving on shift should apply their locks before departing workers remove their locks.
