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" counter-clockwise 180°
Bat the base of the "Y" in either direction
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 valves on each leg of the "Y" by 90 degrees. This allows the water to flow through both hoses simultaneously, providing the necessary water pressure and volume to effectively fight the fire. The other options are incorrect because: A) turning the valve at the base of the "Y" counter-clockwise 180° would likely shut off the water flow entirely; B) turning the valve at the base of the "Y" in either direction may not ensure that both hoses are fully open; and D) turning the valves on each leg of the "Y" 180° would be unnecessary and could potentially damage the valves.
