Detection Tools For Arson Or Fire InvestigationMany accelerants are hydrocarbon-based fuels such as gasoline (petroleum)Download Guide Back to Industry Guides
Fire investigation, sometimes referred to as orgin and cause investigation, is the analysis of fire-related incidents.The principal goal for fire investigators is figuring out how and where a fire started and where foul play is suspected, specially trained arson detection dogs are amongst their ‘tools of the trade’. It is common knowledge that dogs have a keen sense of smell, but the actual degree of sensitivity is amazing. Smell is a dog’s primary sense, and it is 10,000 to 100,000 times more acute than humans. That analogous to being able to see and recognise something 500 meters away, a dog could see and recognise the same object 5000 kilometres away. Or, if you could taste a teaspoon of sugar in your coffee, a dog could taste a teaspoon of sugar in over 3.5 million litres of water. In terms of detecting the residue of volatile organic compounds (VOC) that may be present at a fire scene from common accelerants such as solvents, gasoline (petrol) or diesel fuel, they have a sensitivity of 0.001 part per million (ppm).
Detection Tools For Arson Or Fire InvestigationAnother proven scientific tool used in forensic fire investigations is the photoionisation detector (PID):-
Choosing The Right InstrumentManufacturers tend to offer variants of the same instrument differentiated by functionality and/or performance to suit different budgets but here are some important considerations:-

What are the basic methods of fire investigation?With few exceptions, the proper methodology for a fire or explosion investigation is to first determine and establish the origin(s), then investigate the cause: circumstances, conditions, or agencies that brought the ignition source, fuel, and oxidant together.
What is the first step in a fire investigation?The first step in a fire investigation is the preliminary scene examination/size-up. For best results, a trained fire investigator should be notified about and respond to serious fires or possible arson fires immediately after fire apparatus is dispatched.
What are the techniques used as part of an arson investigation?The arson investigator observes the scene, collects and gathers physical evidence, and interviews witnesses. Using the information obtained, the arson investigator will determine if the fire was accidental or deliberate and identify a suspect.
What type of information is part of a fire investigation?Fire and arson investigators examine the physical attributes of a fire scene and identify and collect physical evidence from the scene. This evidence is then analyzed to help determine if the cause of the fire was accidental or deliberate.
