Lockout/tagout devices are used to ensure what?

Lockout/tagout devices are critical safety mechanisms used to ensure that utility equipment is completely shut off and remains inoperative while maintenance or repair work is performed. This practice is essential to prevent accidental energization or start-up of machinery, which could pose serious hazards to firefighters or maintenance personnel.

By implementing lockout/tagout procedures, a physical barrier or visual warning is placed on the equipment to signal that it must not be operated until the device is removed. This is crucial in hazardous environments where accidental activation could result in injuries or fatalities.

While the other options touch on aspects related to utility management or safety, they do not encapsulate the primary purpose of lockout/tagout devices, which is to ensure the equipment is securely off to protect those working in its vicinity.
