What is the minimum flow rate in gallons per minute (GPM) that a class 2 standpipe must meet during flow testing?

The minimum flow rate that a Class 2 standpipe must meet during flow testing is established at 100 gallons per minute (GPM). This flow rate is critical for ensuring that the standpipe can effectively deliver adequate water supply for firefighting efforts. Class 2 standpipes are designed for use in standard commercial buildings where firefighters may need to connect hoses to the system for fire suppression.

Meeting the 100 GPM threshold ensures that there is sufficient water pressure and volume available to move through the standpipe, facilitating rapid and effective response in emergency scenarios. This standard helps to protect both property and lives by ensuring that the fire department has access to enough water to combat a fire efficiently.

While other options may represent flow rates, none align with the established requirements for Class 2 standpipes as defined by NFPA standards and local building codes. Thus, the selection of 100 GPM directly reflects the regulatory compliance necessary for operational effectiveness.
