Safety & Workforce worked example

Lost Time Injury Rate with lost-time cases of 5 cases: a worked example

Push lost-time cases up to 5 cases and the picture changes. This example computes every intermediate figure at that operating point. Use it to benchmark safety performance for Safety & Workforce against OSHA and industry averages.

The inputs for this scenario

  • Lost-time cases: 5 cases (raised for this scenario; the documented default is 2)
  • Total hours worked: 500,000 hr (unchanged)

Working through the calculation

  • Applying the documented formula (LTIR = lost-time cases × 200,000 ÷ total hours worked) to the inputs above produces each figure below.
  • At this operating point the engine returns 2 per 100 workers for ltir, the number this scenario is built around.
  • At this operating point the engine returns 5 cases for cases.
  • At this operating point the engine returns 500,000 hr for hours worked.
  • At this operating point the engine returns 250 FTE for full-time equivalents.

How this compares with the baseline

  • Against the tool's baseline example, where lost-time cases sits at 2 cases and the headline result is 0.8 per 100 workers, this scenario comes in 150% above the baseline at 2 per 100 workers.
  • It computes your lost-time injury rate per 100 full-time workers from lost-time cases and total hours worked. 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.
