Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

What is the humidity range required for storage temperatures in Tier 1?

1. 20-40%

2. 30-50%

3. 30-60%

4. 40-70%

The correct answer is: 30-60%

The correct answer for the humidity range required for storage temperatures in Tier 1 is 30-60%. This range is specified to ensure that stored medical devices maintain their integrity, functionality, and sterility over time. Proper humidity control in storage environments is crucial because excessive moisture can lead to microbial growth, while too little humidity can cause some materials to degrade or become brittle. In the context of medical device reprocessing, maintaining the appropriate humidity levels helps prevent damage to packaging and assists in preserving the sterility of the devices until they are needed for use, ensuring patient safety. The 30-60% range has been established based on best practices and guidelines within the industry to balance these concerns effectively. Keeping humidity within this range supports the overall aim of the MDRAO to promote safe and effective storage practices for medical devices.
