What is NOT considered a confined space where sprinklers are exempt from installation under NFPA 13?

Living rooms are not considered a confined space under NFPA 13, which is why sprinklers are required to be installed in them. According to the standard, a confined space is typically an area that isn’t designed for continuous occupancy and has limited means of entry and exit. Attics, crawlspaces, and storage rooms often fall into that category, as they are spaces that are usually not occupied regularly and may have restricted access.

In contrast, living rooms are designed for regular use and occupancy, meaning that the risk of fire and the likelihood of needing a sprinkler system for fire protection becomes significant. Therefore, the requirement for sprinkler systems to be installed in living rooms aligns with the goal of protecting areas where people spend time. This understanding clarifies the distinction between different types of spaces and their respective requirements under NFPA 13.
