In an automatic sprinkler system, what is the required maximum spacing between sprinklers in ordinary hazard areas?

• A. 10 feet
• B. 12 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

In an automatic sprinkler system, the required maximum spacing between sprinklers in ordinary hazard areas is 12 feet. This spacing requirement is established to ensure adequate coverage and effectiveness of the sprinkler system in suppressing and controlling fires. Proper spacing helps to minimize the risk of fires spreading, as well as ensuring that each area is effectively protected by water in the event of a fire. The spacing of 12 feet is calculated based on the characteristics of ordinary hazard environments, which typically involve moderate combustibility and a mix of contents, such as office areas or light storage. By adhering to this standard spacing, the design ensures a sufficient overlap of the spray patterns from each sprinkler head, which enhances the overall performance of the system. In contrast, larger spacing would increase the risk of potential fire spread and could result in areas being inadequately covered, which could lead to system failure during a fire event. Maintaining the 12-foot spacing ensures compliance with safety codes and guidelines, promoting a reliable and effective fire suppression strategy.
