Fire Detection, Extinguishment, and Material Tests for an Automated Guideway Transit Vehicle
Tests were conducted in a simulated automated guideway transit vehicle to determine the effectivity of a Halon 1301 fire-extinguishing system during various types of fires, evaluate a photoelectric and an ionization fire detection system, and compare various materials under full-scale fire conditions. A portion of a school bus (770 cubic feet) supplied with an airflow system (300 cubic feet per minute--225 recirculated and 75 fresh air) was used as the test article. Smoke density, temperature, carbon monoxide, and Halon 1301 concentrations were monitored throughout the tests. Hydrogen fluoride (HF) samples were taken during the fire extinguishing tests. The noise level associated with the activation of the explosive charge and release of the compressed gas from the 1301 reservoir is high. In the experiment, levels of 120-132 decibel (Absolute) were recorded. There was no attempt to muffle this noise level to the passengers in an enclosed compartment, since this was beyond the scope of the report.
