NFPA 1145:2022, Guide for the Protection of Outdoor Areas, provides recommended practices to reduce the risk of fire spread and to protect structures, property, and people where outdoor fires, open burning, and outdoor fuel sources present hazards. The Guide covers hazard assessment, strategic fuel management, site planning, and the design and placement of defensible space, firebreaks, and fuel modification zones. It addresses vegetation management, prescribed burning, debris and land‑clearing practices, and the use of hardscape, irrigation, and vegetation selection to reduce ignition potential.

NFPA 1145 discusses fire behavior in wildland‑urban interface and other outdoor settings, recognizing factors such as topography, fuel types, weather, and human activity. It recommends measures for minimizing accidental ignition from outdoor equipment, powerlines, recreational fires, and industrial operations, and details operational controls for planned outdoor fires—permitting, ignition protocols, suppression resources, monitoring, and contingency planning. The Guide also includes guidance on emergency access, water supply and suppression tactics appropriate for outdoor incidents, detection and notification systems, and coordination with incident commanders and land‑management agencies.

The 2022 edition integrates current understandings of landscape‑scale mitigation, community risk reduction, and collaboration among fire authorities, land managers, and property owners. It emphasizes preventative strategies, public education, and documented policies for outdoor burning and vegetation treatments, aiming to balance ecological practices with risk reduction. NFPA 1145 is intended for fire‑service planners, land managers, municipal officials, developers, and property owners seeking best practices to manage outdoor fire hazards and protect vulnerable assets.
