This publication documents the minimum requirements for the safe preparation of compressed oxidant-fuel gas mixtures in cylinders by static methods (addition of one component after another in cylinders). The publication specifically addresses:

• key principles for compressed oxidant-fuel gas mixture manufacture;
• manufacturing feasibility studies;
• gas mixing equipment, filling, and analysis; and
• the audit of oxidant-fuel gas mixture manufacturing procedures and operations.

This publication specifically describes the manufacture of compressed oxidant-fuel gas mixtures under the conditions of gas temperatures and pressures detailed within this publication. The manufacture of liquefied and liquid oxidant-fuel gas mixtures is outside of the scope of this publication.

This publication shall be used in conjunction with the information and principles contained in CGA P-36, The Safe Preparation of Gas Mixtures.
