Revisions to the 2013 version of National Fire Protection Association (NFPA) 52 Vehicular Gaseous Fuel Systems Code will impact upon the design of Compressed Natural Gas (CNG) filling station in the United States, according to a newsletter item published by Las Vegas-based Natural Gas Vehicle Institute (NGVi). NGVi draws attention to a new chapter titled General Fueling Station Requirements, subsection 4.4 Installation Validation, which imposes a Hazard and Operability Analysis (HAZOP).
NGVi says a basic CNG fueling station HAZOP review would include these elements:
- Identify the typical CNG fueling station (all the components combined) to be analyzed.
- Compare the typical CNG fueling station with NFPA 52 and all other codes and standards that govern the design and installation of the station.
- Review industry safety experience as identified in current literature.
- Identify potential hazards of internal and external events leading to potential accidents.
- Analyze potential accident scenarios determined from the hazards analysis.
The end result of the HAZOP analysis is a detailed evaluation of each potentially hazardous condition and recommendations for corrective action.
NFPA develops, publishes, and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. Many NFPA codes and standards appear as mandatory references cited throughout government agency regulations.
修訂的2013年版的美國國家防火協會（NFPA）52車用氣體燃料系統規范會影響壓縮天然氣（CNG）加氣站在美國的設計，根據拉斯維加斯的自然出版時事通訊項目燃氣汽車研究所（NGVi）。NGVi提請注意題為加氣站要求，第4.4安裝驗證，其中規定了危險與可操作性分析（HAZOP）的新的篇章。1301F-3 CNG高壓減壓閥
NGVi說，一個 基本的CNG加氣站HAZOP審查將包括這些元素：
- 識別典型的CNG加氣站（所有組件相結合）進行分析。
- NFPA 52和所有其他管站的設計和安裝規范和標準，比較典型的CNG加氣站。
- 回顧目前文獻中所確定的產業安全方面的經驗。
- 確定內部和外部事件導致事故隱患的潛在危險。
- 從危害分析確定潛在的事故情景分析。
HAZOP分析的最終結果是每個潛在的危險情況和建議采取糾正行動的詳細評測。
NFPA開發，出版和傳播300多共識的法規和標準，旨在最大限度地減少火災及其他風險的可能性和影響。出現許多NFPA規范和標準作為強制性引用整個政府機構的規定。
