Pressure vessel for human occupancy
A Pressure vessel for human occupancy ia a container that is intended to be occupied by one or more persons at a pressure which differs from ambient by at least 2 pounds per square inch (0.14 bar). Since 1977, the American Society of Mechanical Engineers PVHO committee has published standards governing the construction of a number of structures which are defined as Pressure Vessels for Human Occupancy. The current standard is PVHO-1-2019.[1] Similar standards are published by a range of national and international standards organisations.
List of PVHO types
- decompression chambers
- Closed diving bells, also known as dry bells or personnel transfer capsules
- High altitude chambers
- hyperbaric chambers
- hyperbaric stretchers
- medical hyperbaric oxygenation facilities
- recompression chambers
- submarines
- Manned submersibles
- Atmospheric diving suits
Nuclear reactor containments, aerospace cabins, caissons or mild hyperbaric chambers are not considered to be PVHOs according to the standard.
gollark: You know, you *can* use "City", "Ville" and "Town" multiple times.
gollark: Well, you can just use the API to get *everyone's* coords, and filter for a specific person.
gollark: Essentially.
gollark: I actually have a system for remotely controlling a lot of laser-equipped turtles over a websocket thing and firing at people via dynmap, but it is not currently deployed.
gollark: With an entity sensor - or dynmap integration - they can detect the right people, too.
