It is a written system of how hazardous energy will be controlled before a worker is exposed to it. For instance, when repairing a machine, if the machine were started while a worker was still making repairs, the worker could be killed or injured. Lock out/ tag out would prescribe how to turn off all power, lock it in the off position, tag it (what is turned off, by who, when, why) and release or block all stored energy in the machine.

Proper lockout tagout practices safeguard workers from the release of hazardous energy. Workers must be trained in the function of the energy control program and have the skills required for safe application usage and removal of the energy control devices.
29 CFR 1910.147
Lockout-tagout.
Lockout/tagout procedures are commonly used to isolate hazardous energy sources within confined spaces. This involves physically securing energy isolation devices with locks and tags to prevent accidental re-energization of equipment. Additionally, proper training for workers on lockout/tagout procedures is essential to ensure safety during maintenance or repair work.
Only authorized personnel who have been trained in lockout/tagout procedures can remove a lockout/tagout from a machine. This typically includes maintenance workers or operators who have the authority and knowledge to ensure that the machine is safe to operate. The removal should only occur after confirming that all personnel are clear from the machine and that it is safe to restore power. Additionally, the person who applied the lockout/tagout should ideally be the one to remove it, unless they are unavailable, in which case specific procedures should be followed.
