How A Fire Investigation Search Dog Works
The Fire Investigation Search Dog is called out to fires where arson is suspected. The dog searches the fire scene once the fire is out and the scene is cold.
The vapour given off by an ignitable liquid ( eg. Petrol, paraffin, diesel etc. ) is tracked down at speed by the dog.
The dog indicates the location of the substance to the handler. This is done in many different ways, but the most common is a stop and stare at the spot where the substance is.
The dog is then rewarded by the handler for a successful ‘find’ and a sample is removed for laboratory examination.
Success is based on highly skilled training plus the respect, trust and bonding between dog and handler.
The Advantages Of Using Dogs For Fire Investigation
Canines can detect the presence of ignitable liquids with greater sensitivity and accuracy than electronic field equipment so increasing the detection of accelerated fire scenes.
Canines can differentiate between natural hydrocarbons produced during combustion and hydrocarbons introduced in illegal fire setting.
With an arson dog, investigators can quickly pinpoint the location of accelerant residue, which saves the arson investigator time at a fire scene. What once took a person hours or days to uncover, a dog can now find in a matter of minutes.
Because the K-9 has a superior ability to discriminate among scents at a fire scene, the investigator takes fewer samples to the laboratory, thus reducing the cost to the department and, ultimately, the taxpayer. The presence of a canine team has led to a reduction of arson fires in communities.
Through fire-setter prevention programs and community demonstrations, the arson dog teams have made an impact on communities.
