Design of Systems and Apparatus for Cryogenic Fluids

The position of valves and switches for emergency shutdowns shall be accessible and clearly labeled. 

 

UC Practice

 

Nonsulated pipes or vessels should be positioned and/or identified to prevent inadvertent contact with an unprotected part of the body.

 

UC Practice

 

Critical vent areas should be covered, or pointed down (i.e., Dewar necks, and pressure reliefs). 

 

UC Practice

 

All portions of lines that could contain liquid cryogen shall be protected by pressure relief devices. This means that a pressure relief device shall be installed on any portion of a line that could be isolated by shutoff valves.
