Which procedural step involves shutting down, isolating, blocking, and securing machines to control hazardous energy sources?

• A. Electrical Power Protection Program
• B. ESD
• C. Job Briefings
• D. Elimination/Termination of Circuit Power

Answer: (D)

Controlling hazardous energy through shutting down, isolating, blocking, and securing equipment is an energy control action known as Lockout/Tagout. The goal is to prevent any unexpected energization while work is performed by completely removing power and securing the energy sources with locks and tags so the machine cannot restart. This aligns with the option described as eliminating or terminating circuit power, which is the energy isolation part of the process. Other choices don’t describe this safeguarding step: an Electrical Power Protection Program focuses on keeping circuits safe from faults, ESD deals with static discharge, and Job Briefings are about planning safety rather than isolating energy sources.
