The Fire Marshal's Office seeks to provide a safe working and living environment for residents, workers, and travelers within Loudoun County. Key aspects of the mission include:

• Investigation into the origin and cause of fire- and explosive-related incidents in the county as well as offenses related to threats to burn and/or bomb
• Investigation into the release of hazardous materials
• Juvenile firesetter Intervention
• Proactive public fire and life safety education programs
• Rapid and professional emergency response
• Reduction of fire risk through abatement of common fire prevention code violations

Sections
The office is organized in three primary sections:

• Fire and Life Safety Education
• Fire Prevention Code Enforcement
• Investigations

There are several special operational programs, such as the Bomb Squad and the Canine Program, however these are collateral responsibilities assigned to regular staff, which transcend section boundaries.
