A Bibliography Of Published Information Relevant To Fire Toxicity |
| Author: |
Demetrius Kourtides and John Parker |
| Abstract: |
The field of fire toxicity encompasses a wide variety of disciplines and technologies, and for that reason requires literature searches into many areas of knowledge. The 883 references in this bibliography represent the information known by the authors to be available or forthcoming in published form, as of June 30, 1997. This bibliography was prepared to assist those working in this filed to help reduce the hazards of fire to man. |

Full-Scale Aircraft Crash Tests Of Modified Jet Fuel |
| Author: |
Robert H. Ahlers |
| Abstract: |
Crash tests were conducted with two A3 and two RB66 aircraft under impact-survivable crash conditions. The wing tanks in the first RB66 aircraft' contained Jet A fuel modified with an 0.7-percent polymeric additive. The aircraft was crash tested into the specially constructed test site at 104.6 knots. The fuel mist generated by the fuel released from four crash-inflicted openings in the front wing spar was not ignited by the array of ignition sources. The wing tanks in the second RB66 aircraft were filled with JET A fuel modified with O.5 percent of the same polymeric additive. The aircraft was crashed into the test site at 102.4 knots. The test conditions for the second RB66 test were made more severe by increasing the fuel temperature, partially drilling out areas in the front spar to increase the opened fuel spillage area, and by adding four fuel release openings under the wing, larger ignition sources, and operating the engines. The fuel mist burst into flame and followed the aircraft down the test site, continuing to burn until extinguished by the firefighting crew. These full-scale tests indicate that modified fuels have a potential for reducing the postcrash fire hazard and that small-scale tests should be conducted which are representative of full-scale crash conditions to determine the additive concentration to be used in any future crash tests.

A Preliminary Model Study Of A Smoke Removal Concept For Cabin Fire |
| Author: |
C.P. Sarkos, R.M. Johnson |
| Abstract: |
A study was conducted using a simple model of an aircraft cabin to examine a new concept for smoke venting during a cabin fire. Findings were based on continuous smoke and temperature measurements in the model and visual observations. Present ceiling construction materials were of sufficient fire resistance to contain a fire entirely within the cabin enclosure. A significant reduction in cabin smoke level was achieved with a polyethylene ceiling that readily melted immediately above the fire location and provided an opening for smoke removal through the �attic� and eventually outside of the aircraft. Additional studies were recommended to verify the findings of the simple model tests and to examine the practicality of implementing the concept in a real transport aircraft. |

Evaluation of a Halon 1301 System for Aircraft Internal Protection from a Postcrash External Fuel Fire |
| Author: |
Richard Hill |
| Abstract: |
The use of a Halon 1301 fire-suppression system was evaluated in regard to increasing occupant escape time during a ground crash situation with an external fire adjacent to a cabin opening. Tests were conducted in a DC7 fuselage, varying the exit configurations and external wind conditions. Tests were also conducted using a curtain to compartmentize the cabin, with the Halon 1301 concentration and location of discharge being varied. Smoke, temperature, carbon monoxide, oxygen and Halon 1301 levels were continuously monitored during the tests at various locations throughout the cabin. Hydrogen fluoride (HF) and hydrogen bromide (HBr) concentrations were obtained by analyzing samples taken from the cabin at various times. The results indicted that the length of protection from flame penetration through an opening was department upon external wind conditions. Flame penetration was controlled for up to 3.5 minutes with zero wind, but a wind of as little as 2 miles per hour (mi/h), the time was reduced to less than 15 seconds. High HF levels were rapidly inside the cabin, with concentrations ranging from 60 parts per million (p/m), with no wind, to well over 300 p/m with 2-mi/h wind conditions. Test results also indicated that the use of a curtain to compartmentize the cabin could slow the spread of HF (15 to 20 seconds), but it does not lower the levels reached. |
