However,a review of the UMTA materials data bank revealed that in all cases there are sufficient materials to meet the criteria of the Recommended Practices. Moreover, a recent Ul\ATA study, "Assessment of the Benefits and Costs associated with the Adoption of the Recommended Fire Safety Practices for Rail Transit Materials Selection,' Transportation Systems Center, Report U MTA-l\JlA-060098-81-3, December, 1982, found that the cost of implementing the Recommended Practices would be minimal for new vehicle construction.

Recommended fire Safety Practices for Rail Transit Materials Selection Scope The Recommended Fi re Safety Practices for Rail Transit Materials Selection are directed at improving the vehicle interior materials selection practices for the procurement of new vehicles and the retrofit of existing RRT and LRT veh i cl es. Ad opti on of these recommended fire safety practices will help to minimize the fire threat in rail transit vehicles and, thereby, red uce the i nj u ri es and damage resulting from vehicle fires.

ng assemblies should meet the performance criteria during a nominal test period determined by the transit agency. The nominal test period should be twice the maximum expected period of time, under normal circumstances, for a vehicle to come to a complete, safe stop from maximum speed, plus the ti me necessary to evacuate al I passengers from a vehicle to a safe area.
