In post-decon steps, what is typically verified after decontamination is complete?

• A. Documentation of times
• B. Environmental monitoring logs
• C. Inventory counts
• D. Weather data

Answer: (A)

Post-decon verification centers on proving the process actually ran for the required durations and steps, with a clear record to show compliance. The most important verification is documenting the times for each phase—when decon started, how long surfaces were in contact with the decontaminant, rinse durations, and when the process ended. This timing documentation provides traceability that the decon procedure met the specified dwell and contact times, and it supports accountability and future audits.

Environmental monitoring logs can support evidence of effectiveness, but they don’t replace the need for a complete timing record tied to how the decon was executed. Inventory counts and weather data aren’t directly tied to whether the decon was performed correctly, so they’re not the typical verification focus after completion.
