What is the process of rendering machinery inoperative called?

Shutdown Procedure
Lockout/ Tagout
Maintenance Protocol
Energy Isolation

The correct answer is: Lockout/ Tagout

The process of rendering machinery inoperative is best described by the term "Lockout/Tagout," commonly abbreviated as LOTO. This safety procedure involves a specific protocol to ensure that equipment is properly shut down and not able to be started up again until maintenance or repair work is completed. Lockout refers to the physical locking of energy-isolating devices to prevent the transmission of energy, while Tagout involves placing a warning tag on the equipment that indicates it should not be operated. The implementation of LOTO helps protect workers from accidental machine start-up or the release of hazardous energy while they are performing maintenance tasks. This procedure is critical in various industries to uphold safety standards and minimize the risks associated with machinery operation. It ensures that all personnel are aware that the equipment is not to be used until the lockout is removed, making it a fundamental aspect of workplace safety protocols.
