- Note
- "Positive pressure is a pressure within a system that is greater than the environment that surrounds that system. Consequently, if there is any leak from the positively pressured system it will egress into the surrounding environment.
Use is also made of positive pressure to ensure there is no ingress of the environment into a supposed closed system. A typical example of the use of positive pressure is the location of a habitat in an area where there may exist flammable gases such as found on an oil platform or laboratory cleanroom. This kind of positive pressure is also used on operating theaters and in vitro fertilisation (IVF) labs." - (en.wikipedia.org 11.12.2019)
