Question 248Safety & Environmental - Assistant Engineer

The correct answer is B) Classes B and C. The engine room of a vessel is most likely to experience Class B and Class C fires. Class B fires involve flammable liquids and gases, which are common in the engine room due to the presence of fuels, lubricants, and other petroleum-based products. Class C fires involve energized electrical equipment, which is also prevalent in the engine room. In contrast, Class A fires involve ordinary combustible materials, and Class D fires involve combustible metals, which are less likely to be the primary fire hazards in a typical engine room.
