exposure during Fire Test in Tulsa, Oklahoma. This was an R & D test leading to a Fire-resistance Rating of three hours.]] A firestop is a Passive Fire Protection System of various components used to seal Openings in Fire-resistance Rated wall and/or floor assemblies through Bounding , which is based on elaborate fire testing as well as environmental testing, in some cases. Unprotected or unbounded openings in fire separations void the fire-resistance ratings of the fire separations that contain them and thus, both in practical and legal terms, collapse the fire compartments of which these fire separations form a part, which affects the fire safety plan of the entire Building . Firestops are specifically designed to restore the Fire-resistance Rating s of rated wall and/or floor assemblies by bounding the openings through approved firestops. OPENING TYPES
