Programs and Sections

Fire & Explosion Investigations

Accelerant Detection Canine (K-9) Unit
Accelerant Detection canines can detect minute traces of ignitable liquids used in fires and can lead investigators to a specific location where physical samples can be taken for forensic laboratory analysis.

To speak with the on-call Supervisor or request assistance from an Investigator or K-9 team after normal business hours, please call New Hampshire State Police Communications at (603) 223-4381.

Hazardous Materials
The Haz-Mat Unit is operated by a Hazardous Materials Coordinator who oversees and coordinates the response to hazardous materials incidents across the state. There are nine regional hazardous materials teams that operate out of various mutual aid compacts and dispatch centers around the state. The section operates an emergency response vehicle with a vast array of resources to assist the teams with detection, analysis, mitigation and command of hazardous materials incidents. The section also conducts many outreach programs to increase the awareness of certain fire and life hazards associated with the handling, storage and use of hazardous chemicals and materials.

Fireworks Safety & Enforcement
The Fireworks Safety and Enforcement Unit is responsible for the enforcement of all laws and codes relative to the manufacture, transportation, storage, handling and use of pyrotechnics, display and consumer fireworks. This includes the licensing and inspection of retail fireworks stores, inspecting display fireworks events, and the permitting and inspection of pyrotechnic, flame and special effects events. The unit consists of one full time investigator and two part-time investigators. These investigators work closely with our local fire and police departments on enforcement efforts across the state.

Public Education
The Public Education Unit is responsible for developing and distributing public education programs and information to various target audiences. One successful outreach is the section's participation in the Remembering When™ program developed by the NFPA and the CDC. This program incorporates a fire and fall prevention strategy for older adults to allow them to stay safely in their own homes. This section also produces a few publications on a regular basis. Safety Seconds is a short publication with public education tips for the fire service to enhance their local programs. Safety Educator is a publication that is designed for teachers to provide them with tips and tools to incorporate fire and life safety ideas into thier regular school curriculum.

Data Analysis
The Data Analysis Unit collects and analyze emergency incident data submitted by local fire departments. They operate the New Hampshire Fire Incident Reporting System (NHFIRS) which is a part of the National Fire Incident Reporting System (NFIRS) operated by the United States Fire Administration (USFA). The data is submitted electronically by the local fire departments and is then transmitted up to the National Fire Data Center (NFDC) operated by the USFA in Maryland. This data is a critical tool in the toolbox for the division to use to direct fire prevention efforts for the maximum efficiency.
