The Bureau of Investigations is responsible for investigating all fires, building collapses, and carbon monoxide releases, other than from automobiles, which cause death. In addition, the Office of the State Fire Marshal is required to assist any fire chief requesting assistance, and will also respond to requests from law enforcement agencies and from local government boards. The Bureau is commanded by Deputy Fire Marshal Adam Fanjoy. If you have any questions, please do not hesitate to contact us at 603-223-4289 or at fmo@dos.nh.gov.
