Title Methodologies for Calculating Firefighting Agent Quantities Needed to Combat Aircraft Crash Fires.
Publication Date Jul 2012
Media Count 168p
Personal Author J. L. Scheffey R. L. Darwin S. Hunt
Abstract The current method for determining required firefighting agent quantities at an airport is based on the concept of a critical area rectangular box defined by the aircraft length and fuselage width. Aircraft size and construction materials have evolved to an extent that the concepts of critical area, which consists of Theoretical Critical Area and Practical Critical Area need to be studied to ensure they are still valid methodologies for determining the firefighting agent requirements for airports. This analysis addressed various factors in assessing current aircraft rescue and firefighting (ARFF) agent requirements. These factors included the historical development of the existing methods and the recent fire-related loss history. The recent loss history includes the effectiveness of the ARFF response and a fire hazard analysis for threats to occupants in an aircraft and those who have escaped the aircraft. The National Fire Protection Association 403 methodology was found to be acceptable and appropriate for establishing agent quantities.
