Tissue Culture Room Negative Pressure

Airflow shall be from low hazard to high hazard areas.

Tissue culture room negative pressure.

If air pressure is appropriately negative the tissue will be sucked toward the room. This helps the lab maintain sterility. This is an acceptable airflow. The room which is maintained at positive pressure relative to the rest of the world has just one door meaning air can flow only out of the room.

Anterooms may be necessary for certain applications such as clean rooms or tissue culture rooms. Tissue culture rooms should be. Negative pressure room and ventilation requirements a.

Potentially harmful aerosols can escape from the containment of the laboratory room unless the room air pressure is negative to adjacent non laboratory areas. Pressurization in these spaces is tested simply by holding a tissue at the bottom of a door and determining whether the tissue is blown back away or sucked towards the gap. Hold a piece of tissue at the bottom of the closed door.
