What is the maximum diameter of a small handline?

The maximum diameter of a small handline is typically considered to be 2 inches. Handlines are generally used for firefighting on smaller fires or for specific tasks within larger incidents. The 2-inch diameter allows for effective water flow while still being manageable for a single firefighter or a small team to handle. This size is ideal for providing sufficient pressure and reach in a variety of firefighting situations without becoming overly cumbersome.

A diameter of 2 inches strikes a balance between maneuverability and the ability to deliver adequate water to combat fires effectively. This specification is commonly referenced in firefighting manuals and training materials, underscoring its standardization across many fire departments, including CAL FIRE. Having this knowledge is crucial for firefighters, as it helps them understand equipment parameters and capabilities during operations.
