- Abstract
- A cabin fire protection system using Halon 1301, an extinguishing agent previously tested and shown to be effective in suppressing and controlling fires in a simulated transport cabin section and a cargo compartment, is investigated. Tests were conducted in an obsolete bu completely furnished DC-7 passenger cabin equipped with two candidate Halon 1301 dispensing systems, modular nozzle and perforated tube. Under no-fire conditions, continuous measurements were made of the Halon 1301 concentrations at approximately 20 locations; measurements also were made of temperature, noise, pressure and visibility. The modular nozzle system was judted to be best by virtue of its producing more rapid and effective agent distribution resulting in greater potential fire protection capability. Installation of the agent dispensers for both systems along the ceiling minimized the known possible transient adverse effects upon passengers from agent concentration overshoot, discharge noise and overpressure, and reduced temperature. Halon 1301 was found to rapidly permeate all cabin airspaces, including those shielded from the discharge streamlines.
