What is the maximum distance between nozzles for a dry chemical system as per NFPA 17?

The maximum distance between nozzles for a dry chemical extinguishing system, as specified by the NFPA 17 standard, is 6 feet. This guideline ensures that the distribution of the extinguishing agent is effective and covers the intended area to suppress fires adequately.

The 6-foot spacing helps optimize the performance of the system by guaranteeing that the dry chemical can reach and effectively extinguish flames in a timely fashion while minimizing the chances of any areas being left unprotected. Adhering to this standard spacing is critical in ensuring safety and compliance in fire suppression systems. Properly placed nozzles can significantly enhance the system's ability to combat fires in various environments, emphasizing the importance of following these specifications closely.
