What is the standard maximum spacing allowed between sprinkler heads in most installations?

• A. 10 feet
• B. 15 feet
• C. 20 feet
• D. 25 feet

Answer: (B)

The standard maximum spacing allowed between sprinkler heads in most installations is 15 feet. This guideline is established by various codes and standards, including those set by the National Fire Protection Association (NFPA), specifically NFPA 13, which governs the installation of sprinkler systems. The reasoning behind the 15-foot spacing is to ensure optimal coverage and effectiveness of the sprinkler system. By maintaining this distance, each sprinkler can effectively control or suppress a fire within its designated area while preventing gaps that could lead to unprotected spaces. This approach maximizes pressure distribution and water spray patterns, crucial factors in extinguishing fires efficiently. Spacing greater than 15 feet could lead to insufficient coverage and potential fire hazards, as there might be regions where the water distribution would not adequately protect the space. Therefore, following the 15-foot rule helps ensure compliance with safety codes and enhances overall fire protection in buildings.
