Study Notes

Complex lockout/tagout procedures are required for certain applications with multiple energy sources, multiple crews, multiple crafts, multiple locations, multiple employers, multiple disconnecting means, particular sequences, or jobs that continue for more than one work period.
A written plan of execution is necessary for complex lockout/tagout procedures, identifying the person in charge.
Primary responsibility for employees working under group lockout or tagout devices is vested in an authorized employee, and each authorized employee must affix a personal lockout or tagout device when starting work.
Stored energy sources, such as capacitors and springs, must be properly managed before touching or working on associated equipment.
The complex lockout/tagout procedure shall identify the person responsible for verifying that the lockout/tagout procedure is implemented and for ensuring task completion before removing locks/tags.
Equipment cannot be restarted once the lockout/tagout procedure has been initiated, and this must be verified by testing the equipment operating controls.
The procedure shall identify testing requirements, including the test instrument to be used, the person responsible for using it, the boundary of the electrically safe work condition, and the necessity of retesting.
Grounding requirements for the circuit should be established, including the installation of temporary protective grounding equipment for the duration of the task.
A method for transferring responsibility for lockout/tagout during shift changes must be identified in the procedure.
The procedure shall establish coordination methods for jobs or tasks in progress, including related jobs or tasks at remote locations and the person responsible for coordination.
A method for accounting for all persons who could be exposed to hazardous energy during the lockout/tagout must be identified in the procedure.
Lockout is defined as installing a lockout device on all sources of hazardous energy, making operation of the disconnecting means impossible without forcible removal of the lock.
Tagout is defined as attaching a warning tag to the energy isolation device and other energy-isolating equipment in the circuit, making the equipment clearly identifiable as being in a locked-out or tagged-out condition.
