Safety & Workforce worked example

TRIR Calculator with recordable cases of 13 cases: a worked example

What does the result look like when recordable cases reaches 13 cases? The full calculation is worked below with real intermediate numbers. Use it to benchmark safety performance for Safety & Workforce against OSHA and industry averages.

The inputs for this scenario

  • Recordable cases (OSHA): 13 cases (raised for this scenario; the documented default is 5)
  • Total hours worked: 500,000 hr (unchanged)

Working through the calculation

  • Applying the documented formula (TRIR = recordable cases × 200,000 ÷ total hours worked) to the inputs above produces each figure below.
  • At this operating point the engine returns 5.2 per 100 workers for trir, the number this scenario is built around.
  • At this operating point the engine returns 13 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 recordable cases sits at 5 cases and the headline result is 2 per 100 workers, this scenario comes in 160% above the baseline at 5.2 per 100 workers.
  • A figure at this level is achievable when recordable cases is genuinely sustained, not just peaked for a shift. TRIR counts cases equally regardless of severity, so a year with one amputation can show the same rate as a year with five minor stitches — pair it with severity metrics like DART or lost-time rate.
