Answer 1

1. What is the purpose of using a laminar airflow clean bench environment when preparing sterile products?

• Laminar airflow clean bench provides protected workspace to prepare sterile products.
• It prevents the contamination of sterile products from the microorganism.
• HEPA filtered provides a Particulate-free environment
• It is useful in preparing the drug, media, and processing equipment.

2. When cleaning the horizontal laminar airflow clean bench, why do you work from the top to the bottom, back to the front?

Proper cleaning of horizontal laminar airflow is vital in maintaining sterility. It is always cleaned from back to front, top to the bottom by side to side motions to avoid the return of dirt on the airflow.

3. What are the differences in hand placement when preparing sterile products in horizontal vs. vertical laminar airflow clean benches?

In Horizontal airflow, the air pushes horizontally over the workspace and it covers a larger working area. We can place instruments like a metal plate, tissue culture, and microscope. In vertical airflow, air filter present in the top and pushes air downwards. It requires safety measures and most widely used for microbiology, forensic departments.

4. An individual preparing a sterile product in a horizontal laminar airflow clean bench should work at least how far into the hood?

While preparing a sterile product in a horizontal laminar airflow clean bench, the individual should work at least six inches from the hood.

5. Will preparing a sterile product in a laminar airflow clean bench guarantee the preparation of a sterile product?

Yes. Laminar workflow is very efficient in the preparation of a sterile product if the guidelines are followed strictly.

6. Why is protective personal equipment worn when preparing sterile products?

Latex gloves, gowns, face shields, respirators, eye goggles are used especially in preparing antineoplastic agents.
