Lockout Tagout Time with energy-isolation points of 3 points: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop energy-isolation points to 3 points, then walk the calculation through step by step. Estimate lockout/tagout time for Safety & Workforce from the number of energy-isolation points and time per point.

The inputs for this scenario

  • Energy-isolation points: 3 points (the input this scenario stresses; the baseline uses 6)
  • Minutes per point: 4 min (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Lockout/tagout time = energy-isolation points × minutes per point.
  • Lockout/tagout time works out to 12 min at these inputs, and this is the headline figure for the scenario.
  • Isolation points works out to 3 points at these inputs.
  • Minutes per point works out to 4 min at these inputs.
  • Round-trip (lockout + restore) works out to 24 min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where energy-isolation points sits at 6 points and the headline result is 24 min, this scenario comes in 50% below the baseline at 12 min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to energy-isolation points, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes every isolation point takes the same time and that a single technician works sequentially; complex machines with team lockout, permit-required steps, or hard-to-reach valves will run longer than the flat per-point average suggests.

Results at a glance

  • Lockout/tagout time: 12 min (headline result)
  • Isolation points: 3 points
  • Minutes per point: 4 min
  • Round-trip (lockout + restore): 24 min
