What is considered a small diameter hose used in firefighting?

A small diameter hose in firefighting typically refers to hoses that range from 1.5 inches to 1.75 inches in diameter. This classification is significant because these sizes are commonly used for various applications, including standard firefighting operations, supply lines, and for deploying in residential and commercial structures where smaller flows of water are often adequate and easier to handle. Small diameter hoses are advantageous due to their lower weight, making them more manageable for firefighters during operations, particularly in tight spaces or when performing quick attack strategies.

The specific range of 1.5 to 1.75 inches allows for a balance between the ability to deliver sufficient water flow and ease of handling, which is crucial in dynamic and unpredictable firefighting environments. This size range is well-suited for handlines that a single firefighter can operate effectively while still being capable of delivering a powerful stream for suppression efforts.
