Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents.
After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science.
A proven scientific tool used in forensic fire investigations is the photoionisation detector (PID):-
PIDs are quick, simple to use and accurate for the detection of fire accelerants
PIDs are very sensitive to commonly found accelerants and will detect hundreds of gasses and vapours in low concentration
PIDs are non-destructive and will not affect the air sample which can be captured at the same time as the measurement for further lab analysis
PIDs reduce the quantity and cost of lab samples required to reach a conclusion as to the cause of the fire
PIDs are portable and battery powered making them ideal fire and arson investigation instruments
