NFPA 1925: Standard on Marine Fire-Fighting Vessels details requirements for the construction of new marine fire-fighting vessels and the conversion of existing vessels for fire-fighting purposes. It also details the minimum testing and maintenance requirements for marine fire-fighting vessels.
The Standard defines five classes of fire-fighting vessels and specifies:
Changes in the 2013 NFPA 1925 include new definitions.
Updates include new definitions for Category A, Machinery Space of Category A, and Net Positive Suction Head (NPSH) (hsw), plus a revised definition for Fire-Fighting Vessel. NFPA 1925 also reflects vessel classifications and capabilities consistent with the NIMS DHS, focused on upgraded pumping capacity and identified fire-fighting equipment. It's an essential resource for AHJs, local fire authorities, purchasers, and manufacturers of fire-fighting vessels. NFPA 1925 is not a detailed manufacturing purchase specification, but rather a reference for the minimum requirements that should be included within a purchase specification.
