WAC 296-54-517
Lockout/tagout procedures. (1) The
employer must establish and implement written procedures for
lockout/tagout to prevent the accidental start up or release
of stored energy of logging machinery that is shut down for
repairs, maintenance, or adjustments.
(2) Lockout/tagout procedures must contain specific steps
for:
(a) Shutting down, blocking, and securing machines to
control hazardous energy;
(b) Locking and/or tagging out machinery; and
(c) Release from lockout/tagout.
(3) Lockout/tagout procedure details must include at
least the following:
(a) Employees performing maintenance, repairs, or
adjustments have knowledge of the hazardous energy to be
controlled and the means to control the energy.
(b) Logging machine shutdown.
• Apply brakes, swing locks, etc.
• Place the transmission in the manufacturer's specified
park position.
• Lower to the ground or secure each moving element such
as, but not limited to, blades, booms, grapples, buckets,
saws, and shears to prevent a release of stored energy.
• Shut down machinery and ensure that a responsible
person removes and maintains possession of the ignition/master
key.
• Engage hydraulic safety locks when applicable.
• Before working on hydraulic or air systems, relieve
pressure by bleeding tanks or lines and operate controls to
dissipate residual stored energy (pressure).
• Place lockout and/or tagout device.
(4) Release from lockout/tagout. Before lockout or
tagout devices are removed and machinery is started, the work
area must be inspected to ensure that all tools have been
removed, guards are replaced, and employees are in the clear.
(5) The employer must provide padlocks and/or tags for
locking and/or tagging out logging machinery that are durable
enough to withstand the environment.
(6) Tags must have a legend such as "do not start" or "do
not operate." Tags must be placed so they are obvious to
anyone attempting to operate the machinery.
Note:
In lockout, padlocks are commonly used to prevent access to ignition/master switches or battery disconnects.
(7) Energy sources. Stored or residual energy such as
that in elevated machine members, rotating saws, hydraulic
systems, air pressure and springs, must be dissipated or
restrained by methods such as grounding, repositioning,
blocking, chaining, bleeding down, etc.
(8) The employer must provide training to ensure that the
purpose and function of the lockout/tagout program are
understood by employees performing maintenance, repairs, or
adjustments covered by this section. This program must be
reviewed at least annually and training provided as needed. This training may be accomplished through safety meetings.
Note:
See appendix 2 for a sample lockout/tagout program (energy control program).
