NFPA 1400: Standard on Fire Service Training is a new standard that combines and updates NFPA's existing standards 1402, 1403, 1404, 1407, 1408, 1410, and 1451. Not only does it consolidate those previous standards into one document, but its revisions impact all fire training operations and facilities, including facilities and props located at fire stations. The facilities portion of NFPA 1400 (formerly NFPA 1402) was adopted as a standard in 2019, establishing new minimum requirements for all training facilities. It has been updated again for the 2026 edition, affecting new designs and retroactive to all existing training facilities. Examples will be given of live-fire training structures (burn buildings), drill towers, and technical rescue props, including props built into fire stations that require modifications to remain in compliance with NFPA 1400. The operational portion of NFPA 1400 has also been updated, including the section on live fire training (formerly NFPA 1403), and new chapters on technical rescue training and hazmat training have been added.
