Lithium Ion Batteries

R. Meier & P. Kennedy, 2016 Lithium Ion Batteries, Battery Fires, Battery Explosions, Electronics Fires, E-cigarette Fires Since their introduction, there have been many fire and explosion incidents where LI cell or batteries were involved. Sometimes the batteries were the source of ignition and sometime even the source of the fuel. In some cases, however, […]

A Detailed Look at the Necked Vessel Flame Thrower Effect

R. Meier, P. Kennedy, K. Smith, G. Gorbett & P. Powell, 2014 Fire Investigation, Flammable Liquids, Fire Behavior, Necked Vessel Fiame Thrower Effect, In 2013 and 2014 extensive study and laboratory tests were conducted outside the scope of any specific incident or litigation. This data was combined with data collected during case specific research conducted […]

G. Gorbett, W. Hicks, P. Kennedy & R. Hopkins, 2008 Fire Patterns, Full-scale Testing, Fire Science, Fire Dynamics, Heat and Flame Vectors Key questions to be addressed by the researchburns were: (a) patterns persistence through flashover and full room involvement, (b) reproducibility of patterns geometry in minimal variable testing methods, and (c) reaffirmation of standard […]

Pioneer Hotel Report

G. Gorbett, D. Eliassen, P. Kennedy, J. Lentini, D. Smith, 2008 Case Study, Arson, Wrongful Conviction The primary goal of this review is to identify the factors relied upon by the fire investigators in 1970 that led to the conviction of Mr. Taylor for the crime of arson. Depending upon the outcome of that review, […]

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 […]
