70% to pass

While fighting a fire, in order to utilize two hoses from a single 'wye' gate attached to a hydrant outlet, you need only turn the valve handle _______________.

Aat the base of the "Y" in either direction
Bat the base of the "Y" counter-clockwise 180°
Con each leg of the "Y" 90°
Don each leg of the "Y" 180°
AI Explanation

The correct answer is C) on each leg of the "Y" 90°. To utilize two hoses from a single 'wye' gate attached to a hydrant outlet, you need to open the valve on each leg of the "Y" 90° to allow the flow of water to both hoses. This allows the water to be split evenly between the two hoses, providing the desired flow and pressure for firefighting operations. The other options are incorrect because: A) turning the valve at the base of the "Y" in either direction would not split the flow between the two hoses; B) turning the valve 180° counter-clockwise would completely shut off the water flow; and D) turning the valves on each leg 180° would also shut off the water flow to one of the hoses.
