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.

NGVi说，一个 基本的CNG加气站HAZOP审查将包括这些元素：
- 识别典型的CNG加气站（所有组件相结合）进行分析。
- NFPA 52和所有其他管站的设计和安装规范和标准，比较典型的CNG加气站。
- 回顾目前文献中所确定的产业安全方面的经验。
- 确定内部和外部事件导致事故隐患的潜在危险。
- 从危害分析确定潜在的事故情景分析。
HAZOP分析的最终结果是每个潜在的危险情况和建议采取纠正行动的详细评测。
NFPA开发，出版和传播300多共识的法规和标准，旨在最大限度地减少火灾及其他风险的可能性和影响。出现许多NFPA规范和标准作为强制性引用整个政府机构的规定。
