What is the purpose of Lock Out, Tag Out procedures?

The purpose of Lock Out, Tag Out (LOTO) procedures is fundamentally centered on ensuring the safety of workers during maintenance activities. This practice involves disabling machinery or equipment and providing a clear warning that maintenance is being performed. By applying locks and tags to energy-isolating devices, the procedure effectively protects workers by preventing accidental or unauthorized re-energization of the equipment while it is being serviced. This is crucial in preventing injuries that could result from unexpected machine operation, exposure to hazardous energies, or other risks associated with maintenance tasks.

The other options may touch on related aspects but do not address the primary intent of LOTO procedures. For instance, while improving equipment efficiency and limiting access to machinery might be secondary outcomes or related considerations, they do not encapsulate the essence of the Lock Out, Tag Out procedures, which is primarily focused on safeguarding the health and safety of employees engaged in maintenance work. Thus, the emphasis on worker safety makes the selected choice the correct understanding of LOTO procedures.
