Mounds View – Ferrellgas Plan Review <br />Page 3 of 10 <br />October 1, 2007 <br /> <br />5. Over 30 pages of Fisher data sheets were provided for pressure regulators, including ones <br />intended for residential service, yet there is no indication as to where the regulators will <br />be used or what types will be installed. <br />6. No data was provided on the REGO A751 primary shutoff valve indicated in the Incident <br />Prevention Review. <br />7. Other than the tanks, it is expected that all other components will be new and not reused. <br /> <br />Where the submission or this review is silent on equipment, installation methods, procedures, or <br />other fire and safety provisions, it is expected that Ferrellgas will be in compliance with the <br />codes and standards adopted in Minnesota as identified below. It is expected that this review <br />would need to be modified based on information not included in the above list, should all of the <br />relevant material not be provided. <br /> <br />STANDARDS USED TO CONDUCT THIS REVIEW <br /> <br />This plan review is based on the following standards as adopted in Minnesota: <br /> <br />• Minnesota State Fire Code (2007) comprised of the 2006 International Fire Code plus state <br />amendments (MSFC). <br />• Minnesota State Building Code (2007) comprised of the 2006 International Building Code, <br />plus state amendments (SBC). <br />• 2004 edition of NFPA 58, LP-Gas Code, as adopted and amended in Minnesota. <br /> <br />No additional City of Mounds View ordinances or policies were identified to use for this review. <br /> <br />RESULT OF THE PLAN REVIEW – GENERAL COMPLIANCE WITH NFPA 58 <br /> <br />This plan review will first address general compliance with the requirements found in the 2004 <br />edition of NFPA 58, then will focus on the Product Release Prevention and Incident <br />Preparedness Review, also known as an Incident Prevention Review or Fire Safety Analysis. <br /> <br />Tank Installation <br /> <br />1. Tank construction and marking – NFPA 58 Section 5.2.1.1 addresses the types of tanks <br />and construction standards for LP-gas usage. No information was provided in the <br />submission relating to the construction of these three tanks manufactured in 1956, other <br />than to indicate they are ASME. Given that the tanks are over a half century old, <br />Ferrellgas should provide verification that the tanks meet the design, fabrication, testing <br />and marking requirements and are still qualified for LP-gas service according to the <br />ASME Boiler and Pressure Vessel Code, Section VIII (or clearly indicate if a different <br />standard is used). Reuse of tanks fabricated to earlier editions of regulations, rules, codes, <br />or standards, but reinstalled as part of a new installation, should be considered in the risk <br />assessment for this facility (if applicable). <br />2. Pressure Relief Valve Sizing – Exact tank surface areas were not indicated, nor is the <br />proposed size of the emergency pressure relief valve on each tank given, thus it was not
