Safety & Workforce worked example

DART Rate with dart cases of 7.5 cases: a worked example

Push dart cases up to 7.5 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

  • DART cases (days away, restricted, or transferred): 7.5 cases (raised for this scenario; the documented default is 3)
  • Total hours worked: 500,000 hr (unchanged)

Working through the calculation

  • Applying the documented formula (DART rate = DART cases × 200,000 ÷ total hours worked) to the inputs above produces each figure below.
  • At this operating point the engine returns 3 per 100 workers for dart rate, the number this scenario is built around.
  • At this operating point the engine returns 7.5 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 dart cases sits at 3 cases and the headline result is 1.2 per 100 workers, this scenario comes in 150% above the baseline at 3 per 100 workers.
  • It computes your DART rate per 100 full-time workers from your count of days-away, restricted, and transfer 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.
