Lockout Tagout Training

Course Duration
Course Description
Lockout is defined in the Canadian standard CSA Z460-05 (R2010) "Control of Hazardous Energy - Lockout and Other Methods" as the "placement of a lock or tag on an energy-isolating device in accordance with an established procedure, indicating that the energy-isolating device is not to be operated until removal of the lock or tag in accordance with an established procedure".

Lockout is one way to control hazardous energy. See the OSH Answers Hazardous Energy Control Programs for a description of the types of hazardous energy, and steps required in a control program.

In practice, lockout is the isolation of energy from the system (a machine, equipment, or process) which physically locks the system in a safe mode. The energy-isolating device can be a manually operated disconnect switch, a circuit breaker, a line valve, or a block (Note: push buttons, selection switches and other circuit control switches are not considered energy-isolating devices). In most cases, these devices will have loops or tabs which can be locked to a stationary item in a safe position (de-energized position). The locking device (or lockout device) can be any device that has the ability to secure the energy-isolating device in a safe position. See the example of the lock and hasp combination in Figure 1 below.

Tag out is a labelling process that is always used when lockout is required.  The process of tagging out a system involves attaching or using an indicator (usually a standardized label) that includes the following information:

  • Why the lockout/tag out is required (repair, maintenance, etc.).
  • Time of application of the lock/tag.
  • The name of the authorized person who attached the tag and lock to the system.

Note: ONLY the authorized individual who placed the lock and tag onto the system is the one who is permitted to remove them.  This procedure helps make sure the system cannot be started up without the authorized individual’s knowledge.
