Sterilizer Maintenance Record

Manufacturers provide instructions for the operation and care of their products. In general, sterilization equipment must undergo daily and periodic maintenance to ensure accurate, reliable operation (Box C). A maintenance record, the fifth component of quality assurance, must be kept on each sterilizer. It should include the model and serial number, date of servicing, reason for the service (periodic, preventive, or sterilization failure), what was done, and the name or initial of the person performing the service.
