A full room listened attentively as NFPA's Kristin Collette talked about one thing -- doors. In another of the morning's sessions, Kristin gave an overview of NFPA 80 Standard for the Fire Doors and Other Opening Protectives. NFPA 80, which was originally published in 1911, regulates the installation and maintenance of assemblies and devices used to protect openings in walls, floors, and ceilings against the spread of fire and smoke within, into, or out of buildings. The standard applies to many opening protection systems, including fire doors, fire windows, fabric fire safety curtains, and fire dampers. It does not apply to non fire-rated assemblies.The 2010 edition is only the second new edition of NFPA 80 since the 1999 edition. NFPA Journal featured an online exclusive when the latest edition came out as well as a podcast on the changes.
