    Scope - (Show below) - (Hide below)

    1.1This is a guide to developing fire hazard assessments for rail transportation vehicles. It has been written to assist professionals, including fire safety engineers, who wish to assess the fire safety of rail transportation vehicles, during or after their design (see also 1.6). This guide is not in itself a fire hazard assessment nor does it provide acceptance criteria; thus, it cannot be used for regulation.

    1.2Hazard assessment is a process that results in an estimate of the potential severity of the fires that can develop under defined scenarios, once defined incidents have occurred. Hazard assessment does not address the likelihood of a fire occurring. Hazard assessment is based on the premise that an ignition has occurred, consistent with a specified scenario, and that potential outcomes of the scenario can be reliably estimated.

    1.3Consistent with 1.2, this guide provides methods to evaluate whether particular rail passenger designs provide an equal or greater level of fire safety when compared to designs developed based on the traditional applicable fire-test-response characteristic approaches currently widely used in this industry. Such approaches have typically been based on prescriptive test methodologies. The following are examples of such lists of prescriptive tests: the requirements by the Federal Railroad Administration (FRA) (Table X1.1), the former guidelines of the FRA, the requirements of NFPA 130 (Table X3.1), and the recommended practices of the Federal Transit Administration (FTA). Selective use of parts of the methodology in this guide and of individual fire-test-response characteristics from Table X1.1 (or any other set of tests) does not satisfy the fire safety objectives of this guide or of the table. This guide shall be used in its entirety to develop a fire hazard assessment for rail transportation vehicles or to aid in the design of such vehicles.

    1.4This guide includes and applies accepted and clearly defined fire safety engineering techniques and methods consistent with both existing, traditional prescriptive codes and standards and performance based fire codes and standards under development throughout the world.

    1.5This guide provides recommended methods to mitigate potential damage from fires in rail transportation vehicles, by assessing the comparative fire hazard of particular products, assemblies, systems or overall designs intended for use in rail transportation vehicles. Such methods could include changes to the materials, components, products, assemblies, or systems involved in the construction of the rail transportation vehicle or changes in the design features of the vehicle, including the number and location of automatically activated fire safety devices present (see 4.4.4 for further details).

    1.6This guide is intended, among other things, to be of assistance to personnel addressing issues associated with the following areas.

    1.6.1Design and specification of rail transportation vehicles.

    1.6.2Fabrication of rail transportation vehicles.

    1.6.3Supply of assemblies, subassemblies, and component materials, for use in rail transportation vehicles.

    1.6.4Operation of rail transportation vehicles.

    1.6.5Provision of a safe environment for all occupants of a rail transportation vehicle.

    1.7The techniques provided in this guide are based on specific assumptions in terms of rail transportation vehicle designs, construction and fire scenarios. These techniques can be used to provide a quantitative measure of the fire hazards from a specified set of fire conditions, involving specific materials, products, or assemblies. Such an assessment cannot be relied upon to predict the hazard of actual fires, which involve conditions, or vehicle designs, other than those assumed in the analysis. In particular, the fire hazard may be affected by the anticipated use pattern of the vehicle.

    1.8This guide can be used to analyze the estimated fire performance of the vehicle specified under defined specific fire scenarios. Under such scenarios, incidents will begin either inside or outside a vehicle, and ignition sources can involve vehicle equipment as well as other sources. The fire scenarios to be used are described in detail in Section 5.3.

    1.8.1Fires with more severe initiating conditions than those assumed in an analysis may pose more severe fire hazard than that calculated using the techniques provided in this guide. For this reason severe fire conditions must be considered as part of an array of fire scenarios.

    1.9This fire standard cannot be used to provide quantitative measures.

    1.10This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
