What is the term for penetrations through the fire resistive floor structure to allow the installation of telecommunications cables?

• A. Fire stop
• B. Poke-thru
• C. Floor duct
• D. Cable tray

Answer: (B)

The correct term for penetrations through the fire resistive floor structure that allow for the installation of telecommunications cables is "poke-thru." This term specifically refers to the types of devices or fittings that allow cables to pass through a floor while maintaining the integrity of the fire-rated assembly. Poke-thrus are designed to manage cable pathways and connect telecommunications systems across floors without compromising safety standards relating to fire resistance. The other terms do have their own specific meanings within the context of telecommunications and fire safety. A fire stop is a system designed to prevent the spread of fire and smoke through openings in fire-resistive assemblies, which applies more to the materials and methods used to seal penetrations rather than the penetrations themselves. A floor duct refers to a conduit or duct embedded in the floor that can carry electrical and telecommunications cables but does not specifically denote the intentional fire-rated openings. A cable tray is a support system for organizing and managing multiple cables but does not pertain specifically to the action of penetrating a fire-rated floor.
