What does nfpa 13 say about the small room rule?

NFPA 13, the standard for the installation of sprinkler systems, includes provisions known as the "small room rule," which applies to areas with limited dimensions. Specifically, it states that if a room is less than 150 square feet and has a ceiling height of less than 10 feet, a minimum of one sprinkler is required, regardless of the design density. This rule ensures adequate coverage and protection in small, confined spaces where traditional sprinkler design may not apply. Additionally, it emphasizes the importance of proper sprinkler placement to ensure effective fire protection.
