In 2009, Belleville Fire Department was awarded an accelerant detection K-9, also known as an arson dog, named Chewy. Chewy was trained by Maine Specialty Dogs and certified by Maine Criminal Justice Academy. This was made possible by a grant program from State Farm Insurance. Chewy is trained to sniff and locate accelerants, such as gasoline, commonly used to intentionally set fires. Chewy and her handler are the first K-9 investigation team in the City of Belleville.
Fire investigators use the guidelines set forth in NFPA 921 classifying each incident in one of four categories.
• Incendiary - Fires that are intentionally and maliciously set.
• Accidental - Fires caused by non malicious electrical, mechanical, chemical, and other careless means.
• Undetermined - Fires that have more than one possible ignition source and where one specific cause cannot be
determined.
• Natural - Fires ignited by acts of nature, such as lightning.
All fires classified as "Incendiary" will be forwarded to the Belleville Police Department for further investigation. FIU has a close working relationship with the Belleville Police Department and the Arson detectives assigned to each case. Investigators may on some occasion work in conjunction with the Office of the State Fire Marshal (OSFM) and Federal Bureau of Alcohol Tobacco and Firearms (FBATF).
