The 2008 New York City Fire Code requires that all curtains, draperies and hanging fabric in any laboratory, place of public assembly, educational, or common area in any business or residential occupancy be flame resistant as defined by the National Fire Protection Association (NFPA) 701 Standard. Compliance with the requirement must be certified by a holder of a current and valid Certificate of Fitness for Flameproofing issued by the New York City Fire Department (FDNY).
