Under NFPA 13R, what does the clothes closet exemption specify?

• A. All closets must have sprinklers.
• B. No sprinklers in closets meeting specific conditions.
• C. Closets with doors must have sprinklers.
• D. Only wooden closets require sprinklers.

Answer: (B)

The clothes closet exemption in NFPA 13R means that in certain clothes closets you do not have to install sprinkler heads. This exemption applies when the closet is a dedicated clothing closet that is enclosed with doors and is not used to store other combustible materials or items that would significantly increase the fuel load, and it meets the size and configuration criteria defined in the standard. The idea is that these small, enclosed spaces have a limited potential fuel load and fire growth, so providing protection there would add cost without a proportional safety benefit to the rest of the dwelling. If a closet doesn’t meet those conditions (for example, it lacks a door, is too large, or is used to store other combustibles), sprinklers would be required. This is why the best choice is that no sprinklers are needed in closets meeting the specified conditions.
