CGA S-8-2007 RECOMMENDATIONS TO MINIMIZE HAZARDS OF CG-7 PRESSURE RELIEF VALVES AND ANCILLARY DEVICES FOR LIQUEFIED PETROLEUM GAS CYLINDERS FIRST EDITION
In recent years, incidents have occurred that have been attributed to the improper application and maintenance
of the LPG cylinder and CG-7 PRV package. The purpose of this publication is to provide reference material
and guidelines to personnel who fill, store, and distribute LPG or maintain and refurbish LPG cylinders. This
information will promote the safe and proper filling and handling of LPG cylinders as well as the proper selec-
tion, handling and maintenance of the CG-7 PRY. This information is limited to U.S. Department of Transporta-
tion (DOT) and Transport Canada (TC) refillable cylinder designs.
This publication does not address overfill protection devices (OPD). For information on OPD, see NFPA 58,
