Spaces above ceilings requiring sprinkler installation are called what?

• A. Ceiling pockets
• B. Plenum spaces
• C. Riser spaces
• D. Attic voids

Answer: (A)

The main idea here is recognizing the term for the voids that exist just above a finished ceiling where sprinklers may be required. These spaces are called ceiling pockets. They’re the concealed gaps between a dropped or suspended ceiling and the structural ceiling, where heat, smoke, and fire can travel more quietly and spread if not protected. Because of that potential to hide and accelerate a fire, sprinkler protection is often provided specifically in these pockets in low-rise residential designs under NFPA 13R. Plenum spaces refer to HVAC air-handling spaces above ceilings, which is a related concept but not the term used for this question’s context. Attic voids are spaces above an attic or roof area, not the space directly above a finished ceiling. Riser spaces are vertical passages for piping between floors. These terms describe different locations or functions, whereas ceiling pockets describe the void immediately above a finished ceiling that may require sprinklers.
