Backdraft, Flashover, and Other Rapid Fire Progression Phenomena

G. Gorbett, R. Hopkins, 2007 Backdraft, Flashover, Firefighter Injury, Fire Research Rapid fire progression phenomena, such as backdraft and flashover, can result in danger to firefighters. This paper examines current research and divides these phenomena into categories based on fundamental physical and chemical processes. 

Fire Pattern Persistence and Predictability on Interior Finish and Construction Materials During Pre and Post Flashover Compartment Fires.

R. Hopkins, G. Gorbett, P. Kennedy, 2007 Fire Science, Fire Patterns, Flashover, Full-room Involvement, Full-Scale Test Burn, A series of eight full scale tests were conducted in identically constructed, finished and furnished compartments. In each of the tests with one exception all fires progressed to full room involvement. These test burns demonstrated fire pattern persistence […]

Fractional Vaporization of Ignitable Liquids: Flash Point and Ignitability Issues

P. Kennedy, A. Armstrong, 2016 Flashpoint, Flammability Testing, MSDS, Flammable Liquids, Paints, Solvents, Chemicals Explosions or flash fires have occurred under circumstances in which suspected liquid fuel doesnot appear to explain the fuel source because of its high reported flash point.  In some cases, science can explain the fuel source by the application of the […]

A Fire Analysis Tool Revisited – Acoustic Soot Agglomeration in Residential Smoke Alarms.

P. Kennedy, K. Kennedy, G. Gorbett, 2004 Acoustic Soot Agglomeration, Smoke Alarms, Smoke Detector, Fire Investigation, Fire Alarms, This paper produces additional research particularly focusing on the production of acoustic soot agglomeration patterns in both ionization and photo-electric single station residential smoke alarms. Producing new test data, and combining that with previously reported data, this […]

Depth of Calcination Measurement In Fire Origin Analysis

P. Kennedy, K. Kennedy & R. Hopkins, 2003 Fire Patterns, Fire Investigation, Fire Science, Calcination, Fire Investigation Techniques This is a report on a research project into the practical use of measurements of depth of calcination of room-fire exposed gypsum wallboard, under actual fire scene investigation conditions, to discover and illustrate movement and intensity fire […]

Flashpoint and Fire Analysis

P. Kennedy, 1990 Flash Point, Materials Science, Fire Testing, Fire Litigation Many times the flashpoint of an ignitable liquid fuel is a key consideration in fire case litigation. When fuel flammability characteristics become the main issue at the heart of litigation “materials science” comes into play. Few practitioners in the theoretical sciences posses sufficient practical […]
