2.8.3 Lockout/tagout
Lockout/tagout is an isolation process that protects workers from exposure to the uninten‐
tional or inadvertent release of hazardous energy (electrical energy, mechanical potential
energy, etc.).
Lockout/tagout process helps prevent:
– Contact with a hazard while performing tasks that require the removal, by-passing, or deac‐
tivation of safe guarding devices.
– Unintended release of hazardous energy (stored energy).
– Unintended start-up or motion of machinery, equipment, or processes.
Lockout/tagout process
Lockout process involves the installation of a lockout device (for example, a padlock) on an
isolation device (for example, a circuit breaker or a line valve) to isolate energy by engaging a
position that prevents system energization.
Tagout is a labeling process that is always used when lockout is required. Tagout process
involves the use of informative labels (usually a standardized label).
Generally, lockout/tagout process includes:
1.
Identifying which energy sources are present and must be controlled.
2.
Informing all affected employees of the lockout/tagout process.
3.
Proceeding to shut down the system, ensuring that all moving parts have completely
stopped.
4.
Isolating the system from hazardous energy using lockout devices.
5.
Dissipating any residual or stored energy.
6.
Making sure that the lockout device cannot be removed and that the system cannot be
operated inadvertently.
7.
Tagging out the system by attaching or using an information tag or indicator.
8.
Verifying isolation by visually inspecting the system and engaging or activating system
controls (push buttons, switches, etc.).
