Sterilization & Sterile Barrier Manufacturing worked example

EO Residual Hold Time at 12% handling and staging allowance: a worked example

Push handling and staging allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when eo residual hold time in sterilization and sterile barrier manufacturing needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Units awaiting EO residual clearance: 120 units (unchanged)
  • Aeration/off-gassing clearance rate: 12 units / min (unchanged)
  • Handling and staging allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base eo residual hold time = eo residual hold time workload รท eo residual hold time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required eo residual hold time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base eo residual hold time.
  • At this operating point the engine returns 12 % for eo residual hold time allowance applied.
  • At this operating point the engine returns 12 pieces / min for eo residual hold time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where handling and staging allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It converts a load's clearance workload and off-gassing rate into a base hold time, then inflates it by a handling and staging allowance to give a required aeration/quarantine window. 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.

Results at a glance

  • Required eo residual hold time: 11.2 hr (headline result)
  • Base eo residual hold time: 10 hr
  • Eo residual hold time allowance applied: 12 %
  • Eo residual hold time completion rate: 12 pieces / min
