What is the typical spacing range for sprinklers as specified in NFPA 13?

The typical spacing range for sprinklers as specified in NFPA 13 is indeed 8 to 10 feet. This range is established to ensure adequate coverage of the area being protected while also considering potential obstructions and the specific characteristics of the space. Sprinklers functioning within this spacing range help to optimize the effectiveness of the system by providing a uniform distribution of water over the intended area.

When sprinklers are spaced too far apart, there is a risk of insufficient water coverage, which can lead to larger fire spread or uncontrolled flames. Conversely, if sprinklers are placed too closely, it can lead to unnecessary water usage and potentially create other issues such as water damage. Thus, adhering to the recommended spacing guidelines helps ensure both efficiency and effectiveness in fire protection systems.
