What is a primary concern in the design of fire service mains as referred to by NFPA standards?

• A. Cost-effectiveness
• B. Accessibility
• C. Durability
• D. Pressure reliability

Answer: (D)

In the context of NFPA standards, particularly NFPA 24, the design of fire service mains places a primary concern on pressure reliability. This is essential because fire service mains must deliver adequate water pressure for fire suppression systems to function effectively during an emergency. Consistent and reliable pressure ensures that sprinkler systems, hydrants, and other devices can operate as intended to suppress or control fires. Pressure reliability encompasses not just the ability to maintain pressure during normal operations, but also the ability to respond adequately to fluctuations that may arise during fire events or due to operational demands. Ensuring that the fire service mains can handle potential pressure losses and still provide sufficient flow is crucial for the safety and effectiveness of fire protection systems. While cost-effectiveness, accessibility, and durability are important factors in the overall design and installation of fire service mains, they are secondary to the need for reliable pressure to ensure proper functioning during a fire emergency.
