Vertical Laminar Flow Hood Aseptic Technique

Use strict aseptic technique to avoid introduction of contaminants into the hood.

Vertical laminar flow hood aseptic technique.

Cytotoxic agents radioactive agents antimicrobial agents. The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation.

Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. Room air in red enters the system from above the hepa filter. Items not sterile including fingers and hands must be kept. Provide a constant flow of air out of the work area to prevent room air from entering.

Vertical laminar flow hoods. 99 99 particle free air is forced downward toward the work surface. T f using a laminar flow hood in an open room is no safer than preparing products on a countertop. What is the maximum number of particles in a clean room buffer room and ante room.

Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units. While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product. Provide clean air to the working area. Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2.

Manipulative technique is also different in a vertical flow hood. Use precautions to minimize contamination in the product preparation area. 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.
