Does this specify a cleanliness level?

No, use the cleanliness requirement and verification method in your approved program procedure. The calculator only estimates the work you enter.

Where do recleaning events come from?

Use the planned actions or a documented forecast from comparable work. The calculator does not derive a contamination rate or assume how many parts will fail inspection.

Are repeated inspections included automatically?

No, include all planned repeated checks in the inspection count. Recleaning event time covers the cleaning action itself.

Why is drying time excluded from labor?

Unattended drying may occupy a fixture or clean area without consuming continuous labor. Schedule that elapsed time separately unless active supervision is part of your entered work.

Space Cleanliness Inspection Load Calculator

Estimate the labor in your cleanliness control plan. Enter all inspection checks, measured pace, planned recleaning actions and documentation time.

What this calculator does

Plan cleanliness inspection, recleaning and documentation labor from your program procedure.

Formula used

Inspection hours = planned checks ÷ checks per minute ÷ 60
Recleaning hours = cleaning events × minutes per event ÷ 60
Documentation hours = documentation minutes ÷ 60
Total labor = inspection hours + recleaning hours + documentation hours
Total labor minutes = total labor hours × 60

Inputs explained

Planned Cleanliness Checks: All planned inspection checks, including any checks repeated after cleaning.
Cleanliness Inspection Pace: Measured inspection pace for this method and hardware access.
Planned Recleaning Events: Distinct cleaning actions planned before inspection or repeated verification.
Labor per Recleaning Event: Hands-on cleaning labor for one comparable action, excluding inspection.
Cleanliness Record Labor: Labor to complete and review the cleanliness records for this job.

How to use the result

Best suited to cleanliness control Staffing, recleaning workload plan.
The plan does not predict contamination or prove a cleanliness requirement is met. Drying, purge and laboratory waiting time need a separate elapsed-time schedule.
