* The ''XWingSeries'' of books has the Imperial labs on Coruscant that were developing the Krytos Virus designed this way. In case of a containment leak and someone came in, the air would flow in instead of out, preventing the virus from leaving the building.

* This is how the Big Bad Laboratory in MichaelCrichton's ''Literature/{{Prey}}'' defended itself against [[spoiler:{{Nanomachines}}. They failed.]] Mainly because [[spoiler:the swarms [[BodyHorror took control of the humans]]]]. Is it any wonder it failed?

* The smoking salon on the Hindenburg was kept at positive pressure to prevent any wayward hydrogen atoms from sneaking in. In the end it didn't help but it was a nice idea.

* Used in ''SmallSoldiers'' when the two company executives visit the company that made the titular toys' chips (PlayedForLaughs when the down-to-earth toy maker gets surprised and his CorruptCorporateExecutive friend has to explain "Don't worry, that's meant to happen.").
* When the door to Nicodemus' study opens in ''TheSecretOfNIMH'', Mrs. Brisby is met with a blast of wind and a blinding light. Not sure why that would happen, except that [[RuleOfCool it looks cool]].
* Mentioned as a feature of the secret research facility in TheAndromedaStrain.

In RealLife, keeping some 1.2 atmospheric pressures inside is part of airtight sealing of laboratories against dust and other dirt from the outside: even if dust manages to find a crack in the sealing, it'll be blown right out by the pressure difference. On the other hand, labs dealing with dangerious micro-organisms (bio-hazard levels 3 and 4) require the lab to maintain a ''negative'' pressure difference to suck [[ScienceIsBad whatever nastiness is developed there]] right back inside. This trope covers both cases.
