When waste is treated on-site, what proof must be kept?

• A. No records required
• B. Records of autoclave cycles, including temperature, time, load, and validation indicators
• C. Only the date treated
• D. A simple note in the logbook

Answer: (B)

Proof of proper on-site treatment comes from documented evidence that the sterilization cycle actually met the required conditions. Keeping records of autoclave cycles, including the temperature reached, the duration of the cycle, the size or contents of the load, and validation indicators, shows that the waste was exposed to the correct lethal parameters and that the process was verified as effective. Temperature and time ensure the sterilization conditions were sufficient, while the load details confirm the cycle applied to the entire waste batch. Validation indicators, such as chemical indicators or biological indicators, verify that the sterilization occurred inside the load, not just that the machine ran. Without detailed records, you can’t prove the waste was properly treated, making the other options insufficient.
