Method for Selecting Pressure Relief Devices for Compressed Gas Mixtures in Cylinders

inactive
Organization: CGA
Publication Date: 24 August 2005
Status: inactive
Page Count: 43
scope:

This method is applicable to the determination of the proper PRD to use with compressed gas mixtures in cylinders defined in Section 1.

This method is limited to those compressed gas mixtures with known flammability, toxicity (LC50), state, and corrosivity. In addition, the DOT/TC rating and dimensions of the cylinder and the final pressure must be known.

For the selection of PRDs for a single component compressed gas, see CGA S-1.1 [4]. For multicomponent compressed gases (mixtures), the method for selection of relief devices in this publication should be used. Where a mixture is predominantly made up of a single component in a mixture, the gas producer shall determine whether the properties of this mixture dictate it being treated as a single component compressed gas or a gas mixture.
