Dental Autoclave Biological Indicator Weekly Test Checklist [FREE PDF]

Biological indicator (spore) testing of dental autoclaves is mandated by CDC Guidelines for Infection Control in Dental Health-Care Settings (2003/2016) and reinforced by ADA Standards and most State Dental Board Regulations, which require at least weekly monitoring using Geobacillus stearothermophilus or Bacillus atrophaeus spore strips. Failure to perform and document biological monitoring can result in regulatory citations, patient safety risks, and potential legal liability. This checklist g

  • Industry: General Dentistry
  • Frequency: Weekly
  • Estimated Time: 30-45 minutes
  • Role: Sterilization Technician
  • Total Items: 35
  • Compliance: CDC Guidelines for Infection Control in Dental Health-Care Settings (2003/2016) - Section II-E, OSHA 29 CFR 1910.1030 - Bloodborne Pathogens Standard, ADA Standards of Dental Practice - Sterilization Monitoring, State Dental Board Regulations - Autoclave Biological Monitoring Requirements, ANSI/AAMI ST55 - Table-Top Steam Sterilizers Standard

Pre-Test Preparation and Biological Indicator Verification

Confirm that biological indicator products are within expiration, stored correctly, and appropriate for the autoclave type before loading.

  • Is the biological indicator (BI) product within its printed expiration date?
  • Is the BI product the correct type for a steam (Class B or gravity/pre-vacuum) autoclave using Geobacillus stearothermophilus spores?
  • Have BIs been stored in a cool, dry location per manufacturer specifications (not frozen or exposed to heat)?
  • Is a control BI (from the same lot, not sterilized) prepared to incubate alongside the test BI?
  • Is the BI lot number, expiration date, and autoclave ID recorded in the sterilization log before the test begins?

Autoclave Pre-Operation Inspection

Verify that the autoclave is mechanically ready, filled with appropriate water, and that the chamber is clean before loading the test cycle.

  • Is the autoclave reservoir filled with distilled (demineralized) water to the correct level?
  • Is the autoclave chamber door gasket/seal intact with no visible cracks or deformities?
  • Is the chamber interior clean and free of debris, residue, or instrument contamination from prior cycles?
  • Are the autoclave trays and racks in good condition with no rust, corrosion, or damage?
  • Is the autoclave display, pressure gauge, and temperature indicator functioning and readable?

Biological Indicator Load Placement

Confirm proper placement of the BI within the autoclave load to represent the most challenging location for steam penetration.

  • Is the BI placed in the area of the autoclave chamber considered most difficult for steam penetration (typically the front-bottom or geometric center)?
  • Is the BI placed within a representative instrument pouch or wrapped pack to simulate normal processing conditions?
  • Are instrument pouches and packs loaded loosely to allow steam circulation (not overpacked)?
  • Are pouches placed on their edge (vertically) where possible to optimize steam penetration?
  • Is the total load weight and configuration within the autoclave manufacturer's rated capacity?

Sterilization Cycle Parameters and Monitoring

Record and verify that the selected sterilization cycle achieves required temperature, pressure, and time parameters throughout the run.

  • Is the correct sterilization cycle selected for the load type (gravity, pre-vacuum, or flash/immediate-use)?
  • Did the autoclave reach and maintain the required sterilization temperature (e.g., 132°C/270°F for pre-vacuum or 121°C/250°F for gravity) for the full exposure time?
  • Did the cycle complete fully without an error code, interruption, or aborted cycle?
  • Did all external chemical indicators on pouches change to the correct color (pass) at end of cycle?
  • Is the cycle printout or digital log (time, temperature, pressure) saved or printed and attached to the sterilization record?

Biological Indicator Incubation and Result Reading

Confirm correct incubation conditions and accurate reading of both the test and control BIs per manufacturer instructions.

  • Is the processed BI immediately transferred to the incubator alongside the unprocessed control BI after cycle completion?
  • Is the incubator set to the correct temperature for the BI product (typically 55-60°C for G. stearothermophilus)?
  • Are BIs incubated for the full manufacturer-specified time (typically 24-48 hours) before reading?
  • Did the test BI show a NEGATIVE result (no color change/no turbidity indicating no spore growth = sterilization success)?
  • Did the control BI show a POSITIVE result (color change/turbidity indicating spore growth = control is valid)?

Corrective Action Protocol (For Failed or Invalid Tests)

Complete this section only if the BI test result was positive (failure) or the control result was invalid. Document all corrective actions taken.

  • If the test BI was positive (sterilization failure), was the autoclave immediately taken out of service?
  • Were all instruments processed in the failed cycle quarantined and not used for patient treatment?
  • Was the supervising dentist or office manager notified of the sterilization failure immediately?
  • Was the autoclave inspected for operator error, loading issues, water level, or mechanical malfunction before retesting?
  • Was a repeat BI test performed and documented, and did the repeat test show a negative (pass) result before returning the autoclave to service?

Documentation and Record-Keeping

Ensure all weekly spore test results, cycle data, and corrective actions are properly recorded in the sterilization monitoring log.

  • Is the BI test result (pass/fail), lot number, expiration date, incubation start/end time, and technician name recorded in the sterilization log?
  • Is the autoclave cycle printout or digital log reference number attached or cross-referenced to the BI test record?
  • Is the incubator temperature log verified and documented for the incubation period?
  • Are sterilization monitoring records stored in a secure, accessible location for a minimum of 3 years?
  • Is this completed checklist signed by the sterilization technician and reviewed by the supervising dentist or office manager?
