According to NFPA 13, what is the minimum spacing requirement for sprinkler heads?

The minimum spacing requirement for sprinkler heads as specified in NFPA 13 is primarily determined by the type of sprinkler being used. Sprinklers are classified into various categories based on their intended use and spray types, such as standard sprays, quick-response, and others. The spacing can vary significantly; for instance, standard spray sprinklers typically have a spacing requirement of 6 to 15 feet, while other types may have different requirements. This variability is essential to ensure effective coverage and performance of the fire protection system based on the unique characteristics of each space being protected.

Understanding this minimum spacing is crucial for ensuring that the sprinkler system can effectively suppress or control a fire, preventing it from spreading and providing adequate safety for occupants. By aligning the spacing with the type of sprinkler used, designers can optimize the layout and ensure that quick and reliable actions are taken in the event of a fire.
