Expansion Safety
Important Facts:
•
Liquid oxygen at atmospheric pressure expands at a ratio of approximately 860:1
(at 0 psig) when vaporizing into a gas (Figure 1-4). This can occur very rapidly
when exposed to the heat in the atmosphere.
•
Ensure that the specified pressure relief devices are present and functioning properly
in any device that will contain liquid oxygen. This includes transfer hose assemblies.
