When is lockout/tagout applicable in healthcare settings?

• A. Lockout/tagout is used only for electrical systems in operating theatres.
• B. Lockout/tagout restores energy quickly after maintenance.
• C. Lockout/tagout controls hazardous energy during maintenance or repair; isolate energy sources and apply locks/tags to prevent restart.
• D. Lockout/tagout is optional in healthcare settings.

Answer: (C)

Lockout/tagout is used to prevent hazardous energy from being released or a piece of equipment from starting up unexpectedly while maintenance or repair is being done. In healthcare, that means whenever staff work on any device or system that could be energized, pressurized, or have stored energy—electrical, hydraulic, pneumatic, mechanical, thermal, or chemical—the energy sources are isolated and a lock or tag is placed on the energy-control device. This ensures that the equipment cannot be restarted until the work is finished and the locks are removed by the person who applied them. This protects workers from shocks, burns, or injuries from unexpected motion, and it also helps safeguard patients who could be harmed if a device suddenly powers on. After the work is completed and it’s safe, the lockout is removed following proper procedure.

It isn’t limited to electrical systems in operating theatres, and it isn’t about restoring energy quickly. It’s about preventing restart while maintenance is being done, and it’s not optional in settings where energy hazards exist.
