Basic Firefighter Written Practice Exam

What type of hose is specifically used to draft water from a static water source?

1. Supply hose

2. Hard suction hose

3. Attack line

4. Booster hose

The correct answer is: Hard suction hose

The correct option is hard suction hose, which is specifically designed for drafting water from static water sources such as ponds, lakes, or swimming pools. This type of hose is constructed with a rigid or semi-rigid structure that allows it to maintain its shape under vacuum pressure, facilitating the efficient movement of water into the pump. Hard suction hoses are equipped with a strainer at the end, which prevents debris from entering the hose and helps maintain a steady flow of water. When drafting, the pump creates a vacuum that pulls water through the strainer and into the hose, enabling firefighters to access water in locations where traditional water mains might not be available. Other types of hoses, like supply hoses, attack lines, and booster hoses, serve different purposes. Supply hoses are used to transport water from a water source to the pump, attack lines are deployed for directly combating fire, and booster hoses are typically used for small fire suppression operations or quick water delivery. None of these options are specifically adapted for drafting water as effectively as hard suction hose.
