Lock Out, Tag Out Procedure
This procedure establishes the minimum requirements for the lockout of energy isolating devices
whenever maintenance or servicing is done on machines or equipment. It shall be used to ensure that
the machine or equipment is stopped, isolated from all potentially hazardous energy sources and locked
out before employees perform any servicing or maintenance where the unexpected energization or
start-up of the machine or equipment or release of stored energy could cause injury.
All employees are required to comply with the restrictions and limitations imposed upon them during
the use of lockout. The authorized employees are required to perform the lockout in accordance with
this procedure. All employees, upon observing a machine or piece of equipment which is locked out to
perform servicing or maintenance shall not attempt to start, energize, or use that machine or equipment.
Sequence of Lockout
(1) Notify all affected employees that servicing or maintenance is required on a machine or equipment
and that the machine or equipment must be shut down and locked out to perform the servicing or
maintenance.
(2) The authorized employee shall refer to the company procedure to identify the type and magnitude
of the energy that the machine or equipment utilizes, shall understand the hazards of the energy, and
shall know the methods to control the energy.
(3) If the machine or equipment is operating, shut it down by the normal stopping procedure (depress
the stop button, open switch, close valve, etc.).
(4) De-activate the energy isolating device(s) so that the machine or equipment is isolated from the
energy source(s).
(5) Lock out the energy isolating device(s) with assigned individual lock(s).
(6) Stored or residual energy (such as that in capacitors, springs, elevated machine members, rotating
flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or
restrained by methods such as grounding, repositioning, blocking, bleeding down, etc.
(7) Ensure that the equipment is disconnected from the energy source(s) by first checking that no
personnel are exposed, then verify the isolation of the equipment by operating the push button or other
normal operating control(s) or by testing to make certain the equipment will not operate.
Caution: Return operating control(s) to neutral or "off" position after verifying the isolation of the
equipment.
(8) The machine or equipment is now locked out.
Restoring Equipment to Service
When the servicing or maintenance is completed and the machine or equipment is ready to return to
normal operating condition, the following steps shall be taken.
