Question 266Safety & Environmental - Assistant Engineer

The correct answer is C) Halon. The Auxiliary Machinery Flat is a machinery space, and for this type of space, the most effective fixed extinguishing system is typically a Halon system. Halon systems are highly effective at extinguishing fires in enclosed machinery spaces by rapidly reducing the oxygen content and interrupting the chemical chain reaction of the fire. The other options, such as drenching (A) or a water-based system (D), would not be as effective in this type of machinery space. Carbon dioxide (B) systems can also be used, but Halon is generally considered the optimal choice for machinery space fire suppression.
