What is the minimum size hose typically used by firefighters for residential fires?

The minimum size hose typically used by firefighters for residential fires is 1 3/4 inch. This size is favored for its balance between flow rate and maneuverability. A hose diameter of 1 3/4 inches allows firefighters to deliver a sufficient volume of water to combat structural fires effectively while still being manageable for one or two firefighters to handle.

Residential fires often require a rapid response with the ability to quickly deploy hoses in confined spaces, which is another reason why this diameter is commonly used. It can support the necessary flow rates to put out fires in single-family homes, townhouses, and small commercial buildings.

Larger hose sizes, such as 2-inch hoses, are typically reserved for larger operations or when a higher volume of water is needed, while smaller hoses, such as 1-inch, would not provide enough flow to be effective in most fire scenarios in structures. Thus, the 1 3/4 inch size is optimal for residential firefighting needs.
