Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

What is the ideal temperature and humidity range in decontamination?

1. 16-18 Celsius; 20-40% humidity

2. 18-20 Celsius; 30-60% humidity

3. 20-22 Celsius; 40-70% humidity

4. 22-24 Celsius; 50-80% humidity

The correct answer is: 18-20 Celsius; 30-60% humidity

The ideal temperature and humidity range in decontamination is crucial for ensuring the safety and effectiveness of the reprocessing of medical devices. The selected answer, which specifies a temperature range of 18-20 degrees Celsius and a humidity level of 30-60%, is optimal because it strikes a balance that minimizes the risk of microbial growth while allowing personnel to work comfortably. Maintaining a temperature within this range helps to prevent condensation on instruments, which could occur at higher humidity levels. Additionally, the specified humidity range reduces the likelihood of damaging sensitive electronic components or rusting on metal instruments while still ensuring that the environment is conducive to effective cleaning and disinfection. In contrast, other choices present temperature and humidity levels that either fall outside this ideal range or create conditions that may not be as effective for decontamination. For example, temperatures that are too low may not effectively address contaminants, while those that are too high can lead to moisture accumulation and microbial proliferation, inhibiting the decontamination process. Similarly, humidity levels that are too high can compromise the integrity of some instruments and materials, while those that are too low can increase the risk of static electricity, which can harm delicate equipment. Therefore, the selected answer reflects the best practice standards in decontamination
