Can dry scrubbers be used to clean areas in sterile storage?

1. Yes, they are effective

2. No, only wet scrubbers may be used

3. Only for non-critical areas

4. Only if they are HEPA-filtered

The correct answer is: No, only wet scrubbers may be used

Dry scrubbers are not appropriate for cleaning areas in sterile storage because they can potentially introduce contaminants, such as dust or particulate matter, into the sterile environment. Sterile storage areas require a controlled environment where maintaining sterility is paramount. Using dry scrubbers could disturb settled particles and could inadvertently compromise the sterility of the items stored. In contrast, wet scrubbers are effective for cleaning as they typically use a liquid solution, which can help to reduce airborne particles and promote a more thorough cleaning process that maintains the sterile environment. Wet cleaning methods tend to minimize the risk of contamination by ensuring surfaces are cleaner and less likely to harbor particles that could compromise sterility. Thus, understanding the appropriate methods of cleaning sterile storage areas is critical for infection control and overall patient safety, highlighting why the use of dry scrubbers is not recommended.
