What is the correct order to clean a horizontal laminar airflow hood?

The correct order to clean a horizontal laminar airflow hood begins with the hang bar hooks and then proceeds to the ceiling side, followed by the work surface, and finally the opposite side. This methodical approach ensures that the cleaning process is efficient while maintaining the sterile environment necessary for IV preparation.

Starting with the hang bar hooks allows for the removal of any potential contaminants that may have settled there. Next, cleaning the ceiling side addresses airborne particles that could fall onto surfaces below. Cleaning the work surface afterward is crucial because this is where the sterile preparations occur, and one should avoid reintroducing contaminants from other areas. Finally, by cleaning the opposite side last, you minimize the risk of any contaminants transferring to the work surface after it has been cleaned.

This systematic cleaning order emphasizes maintaining aseptic technique and preventing contamination in a critical area where sterile products are prepared and used.
