The OSFM operates a statewide Bomb Squad staffed by Deputy State Fire Marshals (DSFM). The bomb squad responds to emergency calls for found explosives and suspected packages. Should the investigation reveal that a crime has or is occurring the responding DSFM Bomb Technician will continue with the case. The DSFM Bomb Technician normally is responsible for all aspects of the investigation including scene examination, evidence collection, photography, interview & interrogation, and effecting an arrest when appropriate.

They also provide special events standby and regulate the explosive and fireworks industries within the state. The Bomb Squad is supplemented by other DSFM's who are assigned to regional offices and are cross-trained for fire investigation, bomb squad, and code enforcement responsibilities.

The OSFM Bomb Squad also operates an explosive detection canine program. These canines are certified by the Bureau of Alcohol, Tobacco, and Firearms (BATF). Additionally, a new maritime explosive response team has been created which provides the OSFM Bomb Squad with the ability to respond to and manage explosive incidents in or around Maryland's waterways and shipping industry. DSFM Bomb Technicians assigned to the maritime explosive response team receive advanced training in underwater diving, boating, and tactical operations.

Regulation includes the issuance and renewal of firework shooters, explosive blasters, explosive manufacturing, and explosive sales throughout Maryland. Applications for these licenses can be found in the below document section. DSFM's assigned to the Bomb Squad also conduct field inspection of explosive storage facilities and the monitoring and field inspection of explosive use. Additionally, all public firework displays applications are reviewed and approved by the Bomb Squad command.
