What must be done to stored energy as part of the Lockout/Tagout process?

Discharging capacitors is an essential step in the Lockout/Tagout (LOTO) process as it ensures that any residual energy that could cause unintended machine activation or release of stored energy is safely removed. Capacitors can store electrical energy even after a machine is turned off, which can pose a significant hazard if not properly addressed during maintenance or servicing.

When implementing LOTO, workers must identify and control all forms of energy that could potentially cause harm. This includes not only turning off machines and isolating their power sources but also addressing any stored energy, such as that in capacitors, springs, hydraulic systems, or pneumatic systems. By discharging capacitors, workers can mitigate the risk of an unexpected energy release that could lead to accidents or injuries.

In contrast, turning off the main switch, switching off control panels, or allowing machines to idle do not effectively address the potential hazards posed by stored energy. Simply turning off a switch may not eliminate hazardous energy sources, while idling machines can lead to unintended movements or releases, further underscoring the necessity of thoroughly managing stored energy as part of the LOTO process.
