Lockout Tagout Time with energy-isolation points of 15 points: a worked example

Push energy-isolation points up to 15 points and the picture changes. This example computes every intermediate figure at that operating point. Use it to budget LOTO time into maintenance and changeover windows in Safety & Workforce.

The inputs for this scenario

  • Energy-isolation points: 15 points (raised for this scenario; the documented default is 6)
  • Minutes per point: 4 min (unchanged)

Working through the calculation

  • Applying the documented formula (Lockout/tagout time = energy-isolation points × minutes per point) to the inputs above produces each figure below.
  • At this operating point the engine returns 60 min for lockout/tagout time, the number this scenario is built around.
  • At this operating point the engine returns 15 points for isolation points.
  • At this operating point the engine returns 4 min for minutes per point.
  • At this operating point the engine returns 120 min for round-trip (lockout + restore).

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 150% above the baseline at 60 min.
  • It computes total lockout/tagout minutes as energy-isolation points multiplied by the minutes required to lock and verify each point, plus a round-trip figure that also covers restoring energy afterward. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Lockout/tagout time: 60 min (headline result)
  • Isolation points: 15 points
  • Minutes per point: 4 min
  • Round-trip (lockout + restore): 120 min
