Before starting work after lockout/tagout has been applied, what must be verified?

The essential step is to confirm that there is zero energy present in the equipment before work begins. After lockout/tagout devices are applied, you must verify that all energy sources are isolated and that any stored or residual energy has been released or neutralized. This often means trying the controls to ensure the machine cannot energize and using appropriate instruments to confirm there’s no electrical, hydraulic, pneumatic, mechanical, or other energy that could cause unexpected movement. PPE and the presence of a permit don’t guarantee safety on their own; they don’t ensure the machine is actually de-energized.
