What is the county standard GPM for a 1.88 inch attack line?

The county standard for a 1.88 inch attack line is typically established at 175 GPM. This standard is grounded in various factors, including the needs for effective fire suppression, the capabilities of the equipment in use, and the flow characteristics of the hose size.

A 1.88-inch diameter hose offers a balanced approach between maneuverability and the volume of water it can deliver, making it well-suited for many types of structural fires where significant amounts of water are necessary to suppress flames. Setting the flow at 175 GPM allows firefighters to adequately manage the fire while still being able to effectively control the hose and ensure adequate reach and spray pattern.

Overall, understanding standard flow rates not only helps in effective firefighting tactics but also ensures that resources are utilized efficiently, promoting safe and effective operations.
