The mission of Fireman's Hall Museum is to preserve the ongoing history of Philadelphia firefighting through the collection, preservation, and presentation of related artifacts for the education of the public and to encourage sound fire prevention practices. Owned by the City of Philadelphia, the Museum is operated by the Philadelphia Fire Department and supported by the Philadelphia Fire Department Historical Corporation. The Philadelphia Fire Department Historical Corporation was chartered in 1974 to support the creation of the museum for the National Bicentennial.

The Fireman's Hall Museum contains over 200 linear feet of archival material, including personal collections of photographs, scrapbooks, and papers from firemen or relating to Philadelphia fires, and records of the Philadelphia Fire Department, the Fire Insurance Patrol of the City of Philadelphia, and other fire-fighting organizations.
