Lockout is a technique used to:

Lockout is a technique used to:

• A. Prevent hazardous energy from injuring and even killing workers.
• B. A person usually offers the most resistance to electricity.
• C. Special training is required on the use of tags if tags are the only form of protection used.
• D. A current even as low as 1mA can be felt by the body.

Answer: (A)

Lockout is a procedure that keeps workers safe by preventing the release or re-energizing of hazardous energy during maintenance. It works by isolating all energy sources for the equipment—electrical, hydraulic, pneumatic, mechanical, stored, or others—and applying a physical lock to the energy‑isolating device (such as a switch, valve, or breaker). With the lock in place, the machine cannot be started or energy released until the person who applied the lock removes it, after ensuring the area is safe. This direct physical barrier is what makes lockout effective at protecting workers from unexpected startup or energy release that could cause serious injury or death. While tags may be used to indicate that a device is locked out, they are not a substitute for the lock itself and rely on proper training and authorization. The other statements describe electrical properties or tagging procedures rather than the fundamental purpose of preventing hazardous energy.
