What is the typical range of diameters for large diameter hoses?

Large diameter hoses typically range from 4 to 12 inches in diameter. This range is significant because large diameter hoses are primarily used in firefighting for water supply to engines and other equipment, allowing for higher flow rates necessary to combat significant fires.

A diameter starting at 4 inches ensures that these hoses can deliver substantial volumes of water, which is essential in emergency situations where rapid suppression is required. The upper limit of 12 inches accommodates very large flow needs, such as those seen in structural firefighting or in industrial settings.

This choice aligns with industry standards and practical applications of large diameter hoses in various firefighting scenarios. Understanding this range helps facility fire brigade members identify the appropriate equipment and strategies for effective firefighting efforts.
