Question

question 31

a laminar flow hoods hepa filter should be inspected and certified how often?

every month
every year
every 6 months
every 2 years

Explanation:

Identify the regulatory standard

Using the USP 797 Regulations and Sterile Compounding knowledge points, we reference the standards governing sterile compounding environments. Under these guidelines, primary engineering controls (PECs) such as laminar airflow workbenches must maintain specific air cleanliness classifications.

Determine the certification frequency

Using the Laminar Airflow Hood knowledge point, a laminar flow hood's HEPA filter and overall airflow velocity must be tested and certified to ensure operational integrity. According to USP Chapter <797> standards, this certification must occur at least every 6 months, or whenever the hood is relocated, damaged, or undergoes major service.

Answer:

• Every month
• Every year
• Every 6 months (Correct answer)
• Every 2 years
