This report documents design guidelines for the safe use of Compressed Natural Gas (CNG). The report is designed to provide guidance, information on safe industry practices, applicable national codes and standards, and reference data that transit agencies need to review when considering modifications to existing facilities or when planning new bus facilities to safely use CNG as an alternate fuel. The scope of the document is limited to discussing issues related to bus facilities, i.e., bus fueling, storage, and maintenance facilities, and includes design issues related to vehicle safety and personnel training. Among the issues discussed are fuel properties, potential hazards, fuel requirements for specified level of service, applicable codes and standards, ventilation, and electrical classification. Critical fuel related safety issues in the design of the related systems on the bus are also discussed. A system safety assessment program and hazard resolution process is also presented.
