Question

question 11
which of the following statements is true of the air in the compounding area?

the cleanest air is within 6 inches of the sides of the hood.
the cleanest air is within 6 inches of the front of the hood.
the cleanest air is near the top of the hood.
the cleanest air is near the hepa filter.

Explanation:

Analyze airflow in compounding hoods

Using the Laminar Airflow Hood and Direct Compounding Area Airflow knowledge points

• Laminar flow hoods supply HEPA-filtered air to create an aseptic environment.
• The air is cleanest immediately after exiting the HEPA filter before encountering any objects or room air.
• The front edge of the hood is subject to turbulence and room air intrusion, making it the least clean area.
• The sides of the hood are also prone to turbulence and boundary layer effects.
• Therefore, the cleanest air is located closest to the HEPA filter.

Answer:

• The cleanest air is within 6 inches of the sides of the hood.
• The cleanest air is within 6 inches of the front of the hood.
• The cleanest air is near the top of the hood.
• The cleanest air is near the HEPA filter. (Correct answer)
