Who bears the ultimate responsibility for safely attaching lock and tag during repairs?

• A. Employee
• B. Employer
• C. Supervisor
• D. Maintenance crew

Answer: (A)

Lockout/Tagout is about protecting the person doing the work. The worker performing repairs is the one who must isolate every energy source and physically place the lockout device and the warning tag on the equipment. This person is responsible for making sure the energy is secured, ensuring the device cannot be removed without their consent, and confirming zero energy before starting work. The employer provides the program and training, and the supervisor ensures policy and compliance, while the maintenance crew carries out the work, but the actual act of applying the lock and tag—and the accountability for it—rests with the person performing the repair.
