Chemical Inventory Coverage at 72% inventory coverage target: a worked example

This worked example runs the chemical inventory coverage numbers for a tougher week than the baseline: 72% inventory coverage target instead of the typical 100%. Calculate chemical inventory coverage from chemicals with current inventory/sds review, total regulated or reportable chemicals, and a target percentage.

The inputs for this scenario

  • Chemicals with current inventory & SDS on file: 214 chemicals (held at the documented default)
  • Total regulated or reportable chemicals: 245 chemicals (held at the documented default)
  • Inventory coverage target: 72 % (the input this scenario stresses; the baseline uses 100)

Working through the calculation

  • The calculation starts from the formula this tool documents: Chemical Inventory Coverage = chemicals with current inventory/sds review ÷ total regulated or reportable chemicals × 100.
  • Chemical Inventory Coverage works out to 87.35 % at these inputs, and this is the headline figure for the scenario.
  • Gap to inventory coverage target works out to -15.35 points at these inputs.
  • Chemicals with current inventory/SDS review works out to 214 chemicals at these inputs.
  • Total regulated or reportable chemicals works out to 245 chemicals at these inputs.

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 %.
  • Use it during HazCom program audits, before EPCRA Tier II filing, or quarterly as a rolling KPI to catch chemicals that entered the plant without proper documentation. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Chemical Inventory Coverage: 87.35 % (headline result)
  • Gap to inventory coverage target: -15.35 points
  • Chemicals with current inventory/SDS review: 214 chemicals
  • Total regulated or reportable chemicals: 245 chemicals
