NOTE: If 4 bars change to the final colour, the result is successful, the sterilizer works properly. If one or more bars have not turned to the final colour, this shows a failure in sterilizing agent penetration, therefore an equipment malfunction.

Process challenge devices are required to confirm that a sterilisation or decontamination process has been adequately performed.

Process challenge devices are used to provide a challenge to the sterilisation and decontamination processes that are equal to or greater than the challenge posed by the most challenging item routinely processed through the equipment.

PCD’s are another step-in, ensuring decontamination equipment is working correctly and assisting the department by allowing its users to quantify that the equipment is working correctly and within specifications.
