Which aspect is a component of the energy isolation procedure?

• A. Increasing machine uptime
• B. Ensuring that the power is locked at control points
• C. Reducing maintenance time
• D. Ignoring minor energy sources

Answer: (B)

A critical aspect of an energy isolation procedure is ensuring that the power is locked at control points. This step is fundamental to the Lockout/Tagout (LOTO) process because it prevents accidental energization of machinery and equipment during maintenance or servicing. By locking out energy sources at control points, workers can safely perform their tasks without the risk of unexpected machine start-up or release of hazardous energy. This practice significantly enhances workplace safety by safeguarding personnel from potentially severe injuries or fatalities that could arise from inadvertent exposure to energized equipment.

The other options, while they may relate to operational efficiency, do not focus on the core objective of energy isolation, which is to protect workers through controlled energy management.
