The FDNY requires that all decorations in certain occupancies such as Group A, E, I and M occupancies, and Group R-1 college and university dormitories, common areas in Group B, R-1 and R-2 occupancies, and any building or structure used as a place of public gathering, decorations shall be flame resistant. When a material or item is treated with a certified flame-retardant chemical to meet FDNY requirements, the application of the chemical shall be conducted by or under the personal supervision of a C-15 Certificate of Fitness holder. The C-15 holder certifies that decorations and scenery used in a variety of occupancies are flame retardant or inherently flame resistant.
