When should a lockout tagout procedure be employed?

A lockout tagout (LOTO) procedure is crucial for ensuring the safety of employees during service or repair of machinery. This procedure involves physically locking out the power sources and tagging them to prevent them from being inadvertently energized while maintenance is being performed. It applies to all types of machinery, equipment, and systems that could potentially cause harm if accidentally energized.

Using LOTO during any service or repair is essential because it protects workers from the unexpected release of hazardous energy, which can occur not only in electrical systems but also in mechanical systems, hydraulic systems, and thermal processes among others. This comprehensive application of lockout tagout procedures helps mitigate risks associated with servicing equipment that could still carry energy, thereby creating a safer working environment.

The focus on using LOTO during service and repair tasks reinforces the importance of preventive measures and training to ensure that all personnel are updated on their need to employ LOTO every time maintenance work is being conducted, regardless of the setting or the tools being used.
