When is Lock Out - Tag Out required?

Lock Out - Tag Out (LOTO) is a critical safety procedure used to ensure that machines and equipment are properly shut off and not able to be started up again before maintenance or service work is completed. It is specifically required when working on equipment that stores energy, which may pose risks of injury if inadvertently released during maintenance. This includes not only electrical energy, but also potential sources such as hydraulic, pneumatic, thermal, or mechanical energy.

The LOTO procedure prevents accidental machine start-up and energy release, providing a clear safety protocol for workers. By employing locks and tags, workers can ensure that the equipment will not function while they are servicing it, thus significantly lowering the risk of accidents or injuries.

The other options do not meet the criteria for when Lock Out - Tag Out is necessary. Non-hazardous tasks typically do not require such safety measures, as the risks are minimal. Storing tools offsite and conducting routine inspections do not involve the same level of interaction with energy-storing equipment that could present hazards during maintenance, thus LOTO is not mandated in these situations.
