In NFPA 13, the maximum spacing between sprinklers in a light hazard occupancy is:

In NFPA 13, which provides guidelines for the installation of sprinkler systems, light hazard occupancies are defined as areas with a low risk of fire due to the nature of the materials present. According to the standard, the maximum spacing between sprinklers in such environments is 15 feet. This spacing is crucial for ensuring effective coverage and adequate protection against fire spread.

Using a spacing of 15 feet allows for a balance between sprinkler coverage and the potential for fires to be detected and controlled early, minimizing the risk of extensive fire damage and improving overall safety. Proper spacing also ensures that the distribution of water from each sprinkler head can adequately overlap, forming an efficient and effective sprinkler system design.

The other options represent distances that exceed the maximum allowable spacing for light hazard occupancies, which could lead to insufficient coverage and effectiveness of the sprinkler system in those areas. Ensuring compliance with the 15-foot maximum is essential to maintaining safety standards as outlined in NFPA 13.
