In what order should a laminar flow hood be cleaned?

The correct order for cleaning a laminar flow hood is significant for maintaining a sterile environment crucial for compounded sterile preparations. Starting with the hang bar and hooks ensures that any dust or particles that may fall from these areas do not contaminate the cleaner surfaces below. Next, cleaning the ceiling addresses any contaminants that could potentially fall into the work area, reducing the risk of the workspace being contaminated during the cleaning process.

Following the ceiling, the side walls are cleaned, which helps remove any particles or residues that might have accumulated and are still within close proximity to the workbench. Finally, cleaning the workbench itself is important, as it is the area where compounding occurs. This sequence minimizes the risk of cross-contamination and maintains the integrity of the sterile environment.

This comprehensive cleaning strategy ensures that from the highest point to the surface directly in use, there is a systematic approach to maintaining sterility and cleanliness throughout the laminar flow hood.
