Question 3695 Deck General

The correct answer is A) at least two spray patterns of water. The reasoning for this is that the fire main system on a vessel must have enough fire hydrants so that each accessible space can be reached by at least two different spray patterns of water. This requirement ensures adequate coverage and redundancy in the fire suppression system in case one of the spray patterns is obstructed or not functioning properly. The other options are incorrect because B) a water spray or solid stream is too broad, C) a low velocity spray applicator is too specific, and D) 25 psi delivered pressure does not address the need for multiple spray patterns.
