Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation.
Vertical laminar flow hood aseptic technique.
Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood.
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.
The direction of air flow may be horizontal or vertical.
Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units.
Development maintenance of sterile compounding area complete with sterilized equipment supplies 3.
T f using a laminar flow hood in an open room is no safer than preparing products on a countertop.
Use strict aseptic technique to avoid introduction of contaminants into the hood.
Use precautions to minimize contamination in the product preparation area.
Vertical laminar flow hoods.
99 99 particle free air is forced downward toward the work surface.
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.
What is the maximum number of particles in a clean room buffer room and ante room.
Supplies may be arranged to the sides and the back of the area in which manipulations will be performed.
Provide clean air to the working area.
While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product.
The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel.
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.
Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2.
