During which operation is Lockout/Tagout particularly critical?

Lockout/Tagout (LOTO) is particularly critical during the maintenance or servicing of machines or equipment because this is when workers are most at risk for injuries from hazardous energy sources. When machines are being repaired or serviced, they may unexpectedly start up or release hazardous energy if not properly locked out. Implementing LOTO procedures ensures that these energy sources are effectively controlled, helping to prevent accidents and injuries.

During maintenance, workers may need to access dangerous components of machinery, which makes it essential to follow LOTO protocols to secure the equipment. This involves shutting down machines, isolating them from energy sources, and applying locks and tags to prevent accidental re-energization. The appropriate application of LOTO not only protects the maintenance personnel but also reinforces a culture of safety in the workplace.

In other scenarios, such as routine cleaning of equipment or replacing worn-out parts, LOTO may still be important, but it’s especially critical during maintenance or servicing when the potential for exposure to hazardous energy is significantly heightened. Safety meetings are focused on discussion and training rather than direct interaction with hazardous machinery, which is why LOTO is not as critical in that context.
