Vertical Laminar Flow Hood Aseptic Technique

T f using a laminar flow hood in an open room is no safer than preparing products on a countertop.

Vertical laminar flow hood aseptic technique.

The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. 99 99 particle free air is forced downward toward the work surface. Use strict aseptic technique to avoid introduction of contaminants into the hood. Supplies may be arranged to the sides and the back of the area in which manipulations will be performed.

What is the maximum number of particles in a clean room buffer room and ante room. While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product. Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Provide a constant flow of air out of the work area to prevent room air from entering.

Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. Use precautions to minimize contamination in the product preparation area. Cytotoxic agents radioactive agents antimicrobial agents. Vertical laminar flow hoods are often chosen because they resemble on a small scale the design of a laminar flow cleanroom in which fan filter units are typically positioned in the ceiling.

Items not sterile including fingers and hands must be kept. Horizontal flow hoods are most commonly used with the more costly vertical flow hoods being reserved for agents that may produce an environmental hazard e g. The direction of air flow may be horizontal or vertical. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation.

Provide clean air to the working area. Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2. Vertical laminar flow hoods.
