Medium Diameter hoses come in which sizes?

• A. 3 Inch and 2 1/2 Inch
• B. 4 Inch and 6 Inch
• C. 2 Inch and 1/2 Inch
• D. 5 Inch and 3 Inch

Answer: (A)

Medium diameter hoses are the standard attack lines used for typical firefighting tasks, chosen to balance how much water you can deliver with how easy they are to handle. The two sizes that fit this category are 2 1/2 inches and 3 inches. The 2 1/2 inch line is the most common handline because it offers good flow while staying manageable to carry and maneuver. The 3 inch line provides higher flow when you need more volume, such as larger rooms or longer stretches, without jumping up to the larger, heavier large-diameter hoses. Sizes like 4, 5, or 6 inches are considered large diameter and are used for different roles, while very small diameters like 2 inches or 1/2 inch are not classified as medium diameter. So, medium diameter hoses come in 2 1/2 inches and 3 inches.
