Final answer:
The locking out and tagging out safety procedure is crucial when repairing power tools to prevent the tools from inadvertently operating and causing injury.
Step-by-step explanation:
Locking out and tagging out is a safety procedure that is essential before starting repair work on any piece of equipment where unexpected activation could cause injury. An example of such equipment would be power tools. Power tools are often used in various industries and construction sites and can include items such as saws, drills, and sanders.
These tools can cause serious harm if they were to turn on unexpectedly while being repaired or maintained, which is why stringent safety protocols like lockout-tagout (LOTO) are in place to prevent accidents from happening.
