Minimize fire spread to safeguard lives and property by designing and constructing rated wall assemblies according to the 2012 NFPA 221. Keep fire from spreading out of control to protect building occupants, limit property damage, and help fire fighters do their jobs safely and effectively with the 2012 NFPA 221: Standard for High Challenge Fire Walls, Fire Walls, and Fire Barrier Walls. This important Standard presents comprehensive requirements for the design and construction of all types of rated wall assemblies, including high challenge fire walls, fire walls, and fire barrier walls, along with protection of openings and penetrations. NFPA 221 identifies and provides a focus to differentiate between types of fire walls and also includes a general chapter that applies to all types of wall assemblies. The 2012 Edition updates all references and contains editorial revisions to improve usability, consistency, and comprehension. It’s an important resource for authorities having jurisdiction (AHJs), engineers, architects, and construction industry professionals.<\/p>\n
