In the context of lockout/tagout, what does the term "verify isolation" refer to?

• A. Checking that all employees are cleared from the area
• B. Confirming that no energy source is connected
• C. Ensuring that locks are functioning properly
• D. Testing the machinery for movement

Answer: (B)

In the context of lockout/tagout procedures, "verify isolation" specifically means confirming that no energy source is connected to the equipment or machinery that is being serviced. This step is critical to ensure the safety of employees working on the machinery. When isolating energy, it is essential to ensure that all potential energy sources affecting the equipment have been effectively disconnected and that the machinery is not able to operate inadvertently. This includes checking for electrical, hydraulic, pneumatic, thermal, or other energy sources that could pose a hazard. The importance of this verification lies in preventing unexpected machine start-up or release of stored energy, which could lead to severe injuries. Once isolation is verified, workers can safely proceed with their tasks, knowing that the equipment is in a de-energized state. This principle underscores the significance of systematic and thorough processes in maintaining workplace safety during maintenance activities.
