Chemical Inventory Coverage at 110% inventory coverage target: a worked example

Push inventory coverage target up to 110% and the picture changes. This example computes every intermediate figure at that operating point. an environmental manager needs to track chemical inventory coverage against a target

The inputs for this scenario

  • Chemicals with current inventory & SDS on file: 214 chemicals (unchanged)
  • Total regulated or reportable chemicals: 245 chemicals (unchanged)
  • Inventory coverage target: 110 % (raised for this scenario; the documented default is 100)

Working through the calculation

  • Applying the documented formula (Chemical Inventory Coverage = chemicals with current inventory/sds review ÷ total regulated or reportable chemicals × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 87.35 % for chemical inventory coverage, the number this scenario is built around.
  • At this operating point the engine returns 22.65 points for gap to inventory coverage target.
  • At this operating point the engine returns 214 chemicals for chemicals with current inventory/sds review.
  • At this operating point the engine returns 245 chemicals for total regulated or reportable chemicals.

How this compares with the baseline

  • Against the tool's baseline example, where inventory coverage target sits at 100% and the headline result is 87.35 %, this scenario lands almost exactly on the baseline at 87.35 %.
  • It divides the chemicals with current inventory and SDS review by the total regulated or reportable chemicals and multiplies by 100, then reports the percentage-point gap to your coverage target. 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.
