Which size hose is classified as both a supply and attack hose?

• A. 1 inch
• B. 1 3/4 inch
• C. 2 1/2 inch
• D. 3 inch

Answer: (C)

The 2 1/2 inch hose is classified as both a supply and attack hose due to its versatility and application in firefighting operations. As an attack hose, it is capable of delivering water at a sufficient flow rate to combat significant structural fires and is widely used when an aggressive fire suppression effort is required. The diameter allows for a high volume of water, providing the necessary pressure and reach to effectively douse flames. Additionally, as a supply hose, the 2 1/2 inch hose can efficiently transport water from a water source to the fire scene, helping to maintain a steady supply for firefighting efforts. Its durable construction is suitable for the rigors of being used in various scenarios, making it a reliable option for both supplying water and conducting initial fire attack operations. This dual functionality is a key reason this size of hose is commonly used by fire departments.
