What does the term 'lockout/tagout' refer to?

The term 'lockout/tagout' refers specifically to a protocol that ensures machinery is shut down safely and remains inoperable while maintenance or servicing is performed. This practice is critical in preventing accidental start-up of machinery, which could lead to serious injuries or fatalities.

Lockout refers to the physical locking of energy sources, while tagout involves placing a tag on the locked-out device to inform others that the equipment should not be operated until the tag is removed. This process includes identifying all sources of energy, isolating them, and using appropriate locks and tags to secure those controls, ensuring that the equipment cannot be inadvertently energized while work is being done.

In contrast, securing tools, training employees, or evaluating risk, while important aspects of safety programs, do not specifically capture the protective measures associated with lockout/tagout procedures. These other concepts can be part of broader safety initiatives but do not directly relate to the defined process of controlling hazardous energy during maintenance work.
