Buildup of Pressure in Closed Systems,there is a source of refrigeration, pressure can build up. Unless gas can be vented from the system, this pressure increase will continue until eventually either liquid density at ambient temperature is approached or the container ruptures. Starting with saturated liquid at 1 atm, the upper pressure

Condensation,ures of some of the substances that, if present, can be condensed, usually to a solid, at cryogenic temperatures.. From the magnitude of these vapor pressures it can be seen that, in some cases, even undetectable amounts of substances can be condensed, although probably only negligible quantities of

Combustion Hazards,nd for additional attention to system safety. Although carbon monoxide, as well as oxygen and condensed air (see Chapter 9), can present a combustion hazard, here we will be concerned with liquid hydrogen and, to a lesser extent, with liquefied natural gas (LNG).

Safety Problems Needing Further Investigation,echnology (involving new or different experimentation and testing), new safety needs will be disclosed. This occurred, for example, when the decision was made to use liquid hydrogen as a rocket fuel and again when slush hydrogen was planned for use in the National Aero-Space Plane. Each new project

Accidents: Prevention and Examples,d in a safe manner. Safe operation requires excellent maintenance and housekeeping. Because new and different applications of cryogenics are frequently encountered, the possibility of inexperienced operators is always present. Furthermore, a new application might entail usage that does not have any
