Which topic indicates sprinklers are required in spaces with fuel-fired equipment?

• A. Quick-response Sprinklers
• B. Concealed Spaces
• C. Closet Protection Requirements
• D. Garage Protection Requirements

Answer: (B)

Concealed Spaces is the topic that indicates sprinklers are required in spaces with fuel-fired equipment. In NFPA 13R for low-rise residences, hidden or hard-to-observe cavities—like ceiling voids, wall cavities, or spaces behind concealed panels—are treated as higher-risk areas because a fire can start or grow out of sight, especially around fuel-fired equipment such as furnaces, water heaters, or gas appliances. Requiring sprinklers in these concealed spaces helps ensure rapid suppression before the fire can spread through concealed paths to other parts of the home. Other topics address sprinkler types or protection for specific rooms (like closets or garages), but the need to protect hidden spaces where fuel-fired equipment may be present is specifically tied to Concealed Spaces.
