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.

Vertical laminar flow hoods. 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. 99 99 particle free air is forced downward toward the work surface. Use precautions to minimize contamination in the product preparation area.

Items not sterile including fingers and hands must be kept. Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units. The direction of air flow may be horizontal or vertical. Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood.

Cytotoxic agents radioactive agents antimicrobial agents. Manipulative technique is also different in a vertical flow hood. Supplies may be arranged to the sides and the back of the area in which manipulations will be performed. Development maintenance of sterile compounding area complete with sterilized equipment supplies 3.

The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. What is the maximum number of particles in a clean room buffer room and ante room. 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.

Provide clean air to the working area. Use strict aseptic technique to avoid introduction of contaminants into the hood. Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2.
