Question 915 Deck Safety

70% to pass

When the handle of an all-purpose nozzle is in the vertical position and without an applicator, the all-purpose nozzle will _______________.

A shut off the water
B produce a straight stream
C produce high-velocity fog
D produce low-velocity fog
AI Explanation

The correct answer is C) produce high-velocity fog. When the handle of an all-purpose nozzle is in the vertical position and without an applicator, the nozzle is set to produce a high-velocity fog pattern. This high-velocity fog is useful for penetrating fires and reaching areas that a straight stream may not be able to access effectively. The other answer choices are incorrect because: A) shutting off the water would not be the correct function of the nozzle in this configuration, B) a straight stream would not be the output, and D) a low-velocity fog pattern is not the intended function of the nozzle in this vertical, applicator-less setting.
