A fire marshal, in the Unite States and Canada, is often a member of a fire department but may be part of a building department or a separate department altogether. Fire marshal's duties vary but usually include fire code enforcement and/or investigating fires for origin and cause. Fire marshals may be sworn law-enforcement officers and are often experienced firefighters. A fire marshal's duties vary by location. Fire marshals may carry a weapon, wear a badge, and make arrests pertaining to arson and related offenses, or, in other localities, may have duties entirely separate from law enforcement, including building- and fire-code-related inspections. In many states and provinces, the fire marshal is responsible for enforcing laws concerning flammable materials.
