What is the flow rate for Class 2 standpipes?

• A. 250 gpm at 100 psi
• B. 150 gpm at 50 psi
• C. 100 gpm at 65 psi
• D. 200 gpm at 70 psi

Answer: (C)

Class 2 standpipes are designed primarily for use by trained personnel, such as firefighters, and are intended to provide a reliable water supply during fire incidents. The flow rate for Class 2 standpipes is specifically established to ensure adequate water flow for fire suppression efforts. The correct flow rate for Class 2 standpipes is 100 gallons per minute (gpm) at a pressure of 65 pounds per square inch (psi). This specification is established to provide a balance between adequate water volume and manageable pressure for effective firefighting operations. At this flow rate and pressure, the system ensures that firefighters can quickly access and utilize the water supply without causing excessive strain on the equipment or compromising their ability to deliver water effectively to the fire scene. Understanding the correct flow rate and pressure for standpipes is crucial, as it directly influences firefighting strategy and tactics during an incident. This knowledge helps ensure that personnel are prepared and can respond efficiently and safely when engaging with a fire emergency.
