Autoclave Validation

The linked to pdf contains Autoclave Validation training I have presented in person and via teleconference.

The purpose of the training is as follows:

  • What is an autoclave
  • Why we use autoclaves
  • Identify the two main types used by us
  • Detail how to validate an autoclave (including loading patterns)
  • What to look for in an audit

It is important to note that this training was developed in 2008.  Some references may be out of date.  The overall thinking and methodology remains valid.
