• A. A minimum of 6 inches
• B. A minimum of 12 inches
• C. A minimum of 18 inches
• D. A minimum of 24 inches

Answer: (B)

The recommended clearance around fire service mains is crucial for several reasons, including maintenance, accessibility, and ensuring that the system functions correctly during an emergency. In NFPA 24, the standard recommends a minimum clearance of 12 inches around fire service mains. This spacing allows for safe maneuverability for personnel and equipment during inspection and repair activities and helps prevent obstructions that could interfere with the operation of the fire service main. This clearance also aids in the installation of appurtenances and any necessary connections without risking damage to the piping or surrounding structures. Adequate clearance is necessary to maintain the integrity of the fire protection system and ensure that it remains effective in providing a reliable source of water in the event of a fire.
