Cleanroom & Contamination Control worked example

Gowning Consumables Cost at 99% entries requiring a full gown set: a worked example

Push entries requiring a full gown set up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a team needs to budget sterile garments, gloves, masks, wipes, and disposal for a controlled area for a gowning supply period

The inputs for this scenario

  • Gowning events or cleanroom entries: 4,200 entries (unchanged)
  • Gowning consumable cost per entry: 8.75 $ / entry (unchanged)
  • Entries requiring a full gown set: 99 % (raised for this scenario; the documented default is 94)
  • Fixed laundry, disposal, kitting, or stocking cost: 3,600 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable gowning consumables cost = gowning events or cleanroom entries × gowning consumable cost per entry × entries requiring full gown set) to the inputs above produces each figure below.
  • At this operating point the engine returns 39,983 total gowning consumables cost for total gowning consumables cost, the number this scenario is built around.
  • At this operating point the engine returns 9.52 $ / piece for gowning cost per cleanroom entry.
  • At this operating point the engine returns 36,383 $ for variable gowning consumables cost.
  • At this operating point the engine returns 3,600 $ for fixed laundry, disposal, kitting, or stocking cost.

How this compares with the baseline

  • Against the tool's baseline example, where entries requiring a full gown set sits at 94% and the headline result is 38,145 total gowning consumables cost, this scenario comes in 4.82% above the baseline at 39,983 total gowning consumables cost.
  • It computes total gowning consumables cost as entries x cost per entry x full-gown share, plus your fixed laundry, disposal, kitting, and stocking cost. 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.
