Current through Register Vol. 24-14, July 15, 2024
Affected employee
.
An employee
					 who uses a machine or equipment while it is serviced or maintained under
					 lockout or tagout, or who works where such servicing or maintenance is being
					 performed.
Authorized employee
.
A person who
					 locks out or tags out machines or equipment in order to perform servicing or
					 maintenance on that machine or equipment. An affected employee becomes an
					 authorized employee when that employee's duties include performing servicing or
					 maintenance covered under this part.
Capable of being locked out
.
An
					 energy isolating device that has a hasp or other means for a lock to be
					 affixed, or has a locking mechanism built into it. It also means that the
					 device can be locked out without dismantling, rebuilding, or replacing the
					 energy isolating device or permanently altering its energy control
					 capability.
Energized
.
Connected to an energy
					 source or containing residual or stored energy.
Energy isolating device
.
A
					 mechanical device that physically prevents the transmission or release of
					 energy, including but not limited to the following:
(a) A manually operated electrical circuit breaker;
(b) A disconnect switch;
(c) A manually operated switch with conductors of circuit
					 that can be disconnected from all ungrounded supply conductors and allows no
					 pole to operate independently;
(d) A line valve;
(e) A block; and
(f) Any similar device used to block or isolate
					 energy.
Push buttons, selector switches, and other control circuit
					 devices are not energy isolating devices.
Energy source
.
Any source of
					 electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other
					 energy, including gravity.
Hot tap
.
A procedure used in
					 repair, maintenance, and service activities that involves welding on a piece of
					 equipment (pipelines, vessels, or tanks) under pressure, in order to install
					 connections or accessories. It is commonly used to replace or add sections of
					 pipeline without the interruption of service for air, gas, water, steam, and
					 petrochemical distribution systems.
Lockout
.
Placing a lockout device
					 on an energy isolating device, in accordance with an established procedure, to
					 ensure that the energy isolating device and the equipment being controlled
					 cannot be operated until the lockout device is removed.
Lockout device
.
A device with a
					 positive means such as a lock (key or combination type) to hold an energy
					 isolating device in the safe position and prevents the energizing of a machine
					 or equipment. Blank flanges and bolted slip blinds are included.
Normal production operations
.
Using a machine or equipment for its intended production function.
Servicing and/or maintenance
.
Workplace activities such as constructing, installing, setting up, adjusting,
					 inspecting, modifying, and maintaining and/or servicing machines or equipment.
					 These activities include lubrication, cleaning, or unjamming of machines or
					 equipment and making adjustments or tool changes, where the employee may be
					 exposed to the unexpected energization or start up of the equipment or release
					 of hazardous energy.
Setting up
.
Any work performed to
					 prepare a machine or equipment to perform its normal production
					 operation.
Tagout
.
Placing a tagout device
					 on an energy isolating device, according to an established procedure, to
					 indicate that the energy isolating device and the equipment being controlled
					 must not be operated until the tagout device is removed.
Tagout device
.
A prominent
					 warning device, such as a tag and attachment, that can be securely fastened to
					 an energy isolating device according to an established procedure, to indicate
					 that the energy isolating device and the equipment being controlled must not be
					 operated until the tagout device is removed.
