Firestopping products and materials include which of the following?

• A. Caulk
• B. Mortar
• C. Foam
• D. Any of these

Answer: (D)

Firestopping centers on using materials that seal openings and maintain the fire rating of a wall, floor, or ceiling, so flames and smoke can’t spread. Caulk (firestop sealants) is commonly used for small gaps around penetrations and joints. Mortar (cementitious firestop) fills larger voids or spaces around penetrations in fire-rated assemblies. Foam (often polyurethane or intumescent foam) expands with heat to close gaps around cables, pipes, or ducts. Because each of these can be formulated and listed for firestop use, any of these materials can be appropriate when they’re properly rated for the specific assembly and installed according to the manufacturer’s instructions.
