Are tagout devices considered a substitute for lockout devices?

Tagout devices are not considered a substitute for lockout devices unless specifically allowed by the Lockout/Tagout (LOTO) standard. This is a critical element of OSHA's LOTO regulations. The primary purpose of lockout devices is to physically prevent the operation of hazardous machinery, ensuring that equipment is inoperable during maintenance or servicing. Lockout devices provide a means of securing an energy-isolating device, while tagout devices serve as a warning that the machinery must not be operated.

Tagout does have its place within safety procedures, particularly when a lock cannot be applied. However, it is important to understand that a tagout device alone does not provide the same level of safety as a lockout device, because tags are easily removed and do not guarantee that the equipment cannot be operated. The regulations emphasize that when using tagout, additional measures must be implemented to ensure safety, which may include notifying all affected employees and implementing a means to provide physical hazard control. Therefore, relying solely on tagout in place of lockout is generally inadequate unless specific alternative measures approved by the standard are incorporated into the safety protocols.
