What must be considered when designing a sprinkler system for high-rise buildings?

• A. The aesthetic appeal of the buildings
• B. Water supply pressure and flow requirements
• C. The color of the sprinkler heads
• D. Proximity to fire hydrants

Answer: (B)

When designing a sprinkler system for high-rise buildings, one of the most critical factors to consider is the water supply pressure and flow requirements. High-rise buildings often have unique challenges related to their height, such as the need for adequate pressure to deliver water to the upper floors. As buildings increase in height, the vertical distance that water must be pumped also increases, which can decrease water pressure at the higher elevations if not properly addressed. The NFPA 13 standard emphasizes ensuring an adequate water supply, both in terms of pressure and flow, to effectively suppress a fire. The sprinkler system must be designed so that it can deliver sufficient water to cover the entire area of operation, taking into consideration the maximum demand that may occur due to fire conditions. This involves calculating the hydraulic requirements that ensure the system operates effectively during an emergency. Other factors, like aesthetic considerations or the proximity of fire hydrants, may play a role in the overall planning and acceptance of a fire protection system, but they do not directly influence the operational effectiveness and compliance with the safety standards required for high-rise buildings. Therefore, focusing on the water supply pressure and flow requirements is fundamental in ensuring that a sprinkler system can perform adequately in high-rise scenarios.
