Fire Research Lab

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Fire Research Laboratory (FRL), completed in 2003, is the world’s largest research laboratory that is dedicated to fire scene investigations. FRL scientists utilize its unique structure and sophisticated instrumentation to investigate fire scene phenomena; conduct forensic fire science and engineering tests; and analyze fire growth and dynamics questions.

The FRL conducts investigations that involve fire scene reconstruction; flashover studies; electrical fire cause evaluation; and validation of fire pattern analysis indicators. It also participates in important investigations regarding the impact of accelerants on fire growth and spread, ignition studies and electrical fire cause analysis.
