What is considered a medium diameter hose in firefighting?

A medium diameter hose in firefighting is typically classified as one that measures between 2.5 inches and 3 inches in diameter. This size is crucial for certain firefighting operations as it allows for a balance between sufficient water flow and manageable handling characteristics.

Hoses of this diameter are often used for situations where a higher flow of water is needed, such as protecting exposures, supplying large handlines, or for medium to large fire operations. The design and diameter also help with the ability to maintain adequate pressure while delivering an effective stream to combat fires.

Larger hoses, above 3 inches, are usually categorized as large diameter hoses and are primarily used for supply lines or operations that require even higher flows, while smaller hoses, usually under 2 inches, are used for handlines and specific firefighting scenarios where mobility and ease of handling are more important. Recognizing these classifications helps firefighters understand what equipment is appropriate for varying situations encountered in the field.
