NFPA 58, Liquefied Petroleum Gas Code, has requirements for installations in areas with heavy snowfall, which were first added in a TIA in the 1992 edition and then added to the 1995 edition. The requirements were the result of fatalities due to unusually heavy snow in Lake Tahoe, CA
area during the winter of 1992-93 where the snowfall was sufficient to cover propone tanks, move tanks, and break piping systems.
The Foundation is initiating a project to develop the technical substantiation for threshold values for heavy snowload criteria for the NFPA 58 Technical Committee.
If you have information to share, or are interested in serving on the Technical Panel for the Project, please respond.
