Which items should locks and tags be applied to?

Locks and tags should be applied to valves and mechanical blocks as part of the Lockout/Tagout (LOTO) procedures. This is essential for ensuring that energy sources are effectively controlled during maintenance or servicing activities. Applying locks and tags to valves prevents unauthorized operation and helps isolate the equipment from its energy source, safeguarding workers from the unexpected release of energy that could lead to accidents or injuries.

Valves are critical in controlling fluid and gas flow, and locking them out ensures they remain in a safe position during maintenance. Mechanical blocks serve a similar function by physically preventing movement and ensuring machinery does not operate while maintenance is underway. Together, these actions contribute significantly to workplace safety by minimizing the risks associated with hazardous energy.

Utilizing locks and tags on just electrical panels, hydraulic systems, or toolboxes does not encompass the broader range of equipment and machines that require energy control measures. It’s crucial to recognize that LOTO procedures must be applied to all energy sources that could pose a risk, thus emphasizing the importance of valves and mechanical blocks as part of comprehensive safety practices.
