positive pressure
Positive pressure refers to a condition where the pressure within a system or area is higher than the pressure in the surrounding environment. This is commonly used in ventilation systems to maintain clean and controlled environments, such as in hospitals and laboratories. Positive pressure helps to prevent the entry of contaminants or pathogens by ensuring that air flows outwards from the controlled area, keeping it sterile and safe. It can also be used in industrial processes to control dust and fumes, as well as in clean rooms to protect sensitive equipment from contamination. Overall, positive pressure is essential for maintaining a healthy and controlled environment in various settings.
examples
- Operating rooms in hospitals are maintained at positive pressure to prevent the entry of airborne bacteria and contaminants, reducing the risk of infections during surgeries.
- Pharmaceutical manufacturing facilities use positive pressure to ensure that the production area remains sterile and free from contaminants that could compromise the quality of the products.
- Clean rooms in semiconductor manufacturing plants are designed with positive pressure to protect delicate electronic components from dust particles and other impurities that could affect their functionality.
- Isolation rooms in healthcare facilities are kept at positive pressure to contain infectious diseases and prevent them from spreading to other areas of the facility.
- Animal research facilities use positive pressure in animal housing areas to maintain a clean and controlled environment for the health and safety of the animals and researchers.
