Fire Detection, Extinguishment, and Material Tests for an Automated Guideway Transit Vehicle.

Abstract

This report describes 27 fire tests performed in a mockup (modified school bus) of an automated guideway transit vehicle. There were a number of significant findings relative to fire safety in this type of vehicle. First, Halon 1301 was found to be effective in extinguishing typical seat fires, but generated extremely high noise levels during discharge; however, significant reductions in noise were achieved by modifying the discharge nozzle. Another important finding was that in all tests fires, the photoelectric detector responded more quickly than did the ionization detector. Finally, by studying various seat fire ignition sources, it was concluded that the underseat fire was the most severe condition. (Author)
