K9 Information

Accelerant Detection Teams assist fire investigators in locating areas for collection of evidence samples for laboratory analysis at fire scenes. An ignitable liquid is an accelerant when it is intentionally used to start a fire or increase the growth or spread of a fire. HCFMO canine handler teams are used to detect possible evidence of accelerant use at a fire scene. HCFMO canines are trained to indicate to the trace presence of 14 ignitable liquids. HCFMO canine teams are certified through the North American Police Work Dog Association, The Texas State Fire Marshal’s Office, and the Canine Accelerant Detection Association. Both HCFMO K9s were donated by K9s4Cops.
