  • Authorized employee: An employee who locks or tags machines or equipment in order to perform servicing or maintenance.

    Affected employee: An employee who is required to use machines or equipment on which servicing is performed under the Lockout/Tagout standard or who performs other job responsibilities in an area where such servicing is performed.

    Other employees: All employees who are or may be in an area where energy control (LO/TO) procedures may be utilized.

    Capable of being locked out: An energy-isolating device is considered capable of being locked out if it is designed with a hasp or other means of attachment to which a lock can be affixed, has a locking mechanism built into it, can be locked without dismantling, rebuilding, or replacing the energy-isolating device or permanently altering its energy control capability.

    Energized: Machines and equipment are energized when they are connected to an energy source or they contain 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 manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and, in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy. Push buttons, selector switches, and other control circuit type devices are not energy isolating devices.

    Energy source: Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy.

    Lockout: The placement of a lockout device on an energy-isolating device, in accordance with an established procedure, ensuring that the energy-isolating device and the equipment being controlled cannot be operated until the lockout device is removed.

    Lockout device: Any device that uses positive means, such as a lock, blank flanges and bolted slip blinds, to hold an energy-isolating device in a safe position, thereby preventing the energizing of machinery or equipment.

    Normal production operations: Utilization of a machine or equipment to perform its intended production function.

    Servicing and/or maintenance: Workplace activities such as constructing, installing, setting up, adjusting, inspecting, modifying, maintaining and/or servicing machines or equipment, including lubrication, cleaning or un-jamming of machines or equipment, and making adjustments or tool changes, where employees could be exposed to the unexpected energization or startup of the equipment or release of hazardous energy.

    Tagout: The placement of a tagout device on an energy-isolating device, in accordance with an established procedure, to indicate that the energy-isolating device and the equipment being controlled may not be operated until the tagout device is removed.

    Tagout device: Any prominent warning device, such as a tag and a means of attachment, that can be securely fastened to an energy-isolating device to indicate that the machine or equipment to which it is attached may not be operated until the tagout device is removed.
