Florida Fire State Practice Exam

Which type of hose is specifically designed for drafting water from static sources?

1. Attack hose

2. Hard suction hose

3. Supply hose

4. Flexible hose

The correct answer is: Hard suction hose

The correct choice for the type of hose specifically designed for drafting water from static sources is hard suction hose. This hose is constructed to withstand the vacuum created when water is drawn from sources such as ponds, lakes, or other bodies of water that do not have a pressurized supply. Hard suction hose typically features a rigid or semi-rigid design that can maintain its shape under the stress of atmospheric pressure when water is being drafted, ensuring an efficient flow to the pump. In addition to the structural design, hard suction hoses are equipped with threaded connections that allow for secure attachment to both the water source and the pump, preventing the loss of suction. This capability makes them essential for operations where the water source is not pressurized and requires a vacuum to access. Other types of hoses, like attack hoses and supply hoses, serve different functions in firefighting. Attack hoses are primarily designed for delivering water to the fire and are generally flexible and lightweight. Supply hoses, on the other hand, are utilized to transport water from a static source or hydrant to the fire apparatus but do not specifically handle the drafting process. Flexible hoses, while adaptable for various uses, lack the structural integrity required for drafting applications.
