70% to pass

Each fire hydrant serving machinery spaces containing oil fired boilers, internal combustion machinery, or oil fuel units must be equipped with a _______________.

A marine strainer
B pick axe
C low-velocity spray applicator
D fireman's outfit
AI Explanation

The correct answer is C) low-velocity spray applicator. The regulations set forth by the US Coast Guard require that each fire hydrant serving machinery spaces containing oil fired boilers, internal combustion machinery, or oil fuel units must be equipped with a low-velocity spray applicator. This specialized nozzle is designed to provide a gentle, low-pressure spray pattern that is effective for fighting fires in these types of machinery spaces without causing further damage to the equipment. The other options are incorrect because a marine strainer is used to filter water, a pick axe is not a firefighting tool, and a fireman's outfit refers to the personal protective equipment worn by firefighters, not a specific hydrant nozzle requirement.
