SFRM is typically applied to which structural elements?

• A. Beams and columns
• B. Floors and ceilings
• C. Non-structural partitions
• D. Exterior cladding

Answer: (B)

SFRM is a spray-applied fire-resistive material used to protect structural elements so the structure retains its strength and stability during a fire, giving the needed fire-resistance rating. It’s typically applied to floors and ceilings because these assemblies are key load-bearing paths and define the fire-resistance rating of the floor/ceiling system; protecting the framing in these areas helps prevent rapid heat buildup that could lead to collapse. Non-structural partitions or exterior cladding aren’t the primary targets for SFRM, since they aren’t the structural members whose integrity must be preserved to a specific fire-rating during an incident.
