Question 1944Deck General70% to pass
Vessels required to be equipped with an approved backfire flame arrester are _______________.
AI Explanation
The correct answer is C) all those with gasoline engines.
Vessels with gasoline engines are required to be equipped with an approved backfire flame arrester per US Coast Guard regulations. This is because gasoline engines are prone to backfiring, which can potentially ignite any flammable vapors in the engine compartment. The backfire flame arrester acts as a safety device to prevent these flames from escaping the engine and causing a fire. In contrast, diesel engines do not have the same backfiring risk, and large engines are not specifically singled out in this regulation.
