What is the purpose of a lockout tagout system?

The purpose of a lockout tagout system is fundamentally to ensure that electricity is shut off and to prevent unintended use of machinery or equipment during maintenance or servicing. This system is critical in the safety protocols for working with electrical systems and machinery because it prevents the unexpected energization or startup of equipment, which can lead to serious injuries or fatalities.

By using locks and tags, workers can effectively communicate that a piece of equipment should not be operated. This is especially vital in environments like firefighting or industrial maintenance where the risk of injury can be high. When a lock is applied, it physically prevents anyone from operating the equipment, while the accompanying tag provides a clear message about the status and the reason for the lock.

Thus, while the other options may relate to aspects of electrical safety, none encapsulate the full scope and purpose of a lockout tagout system as effectively as ensuring that equipment is not only shut off but also secured from unintended use.
