Question 1953Deck General70% to pass
On a small passenger vessel, backfire flame arrestors are installed on a/an _______________.
AI Explanation
The correct answer is A) gasoline powered engine.
Backfire flame arrestors are required to be installed on the air intake of gasoline powered engines to prevent ignition of any flammable vapors outside the engine. This is a safety requirement specified in the Code of Federal Regulations (CFR) for small passenger vessels.
The other options are incorrect because backfire flame arrestors are not required on natural gas (propane) engines, turbocharged diesel engines, or oil-fired turbine or reciprocating steam engines, as those engine types do not have the same risk of backfire ignition that gasoline engines do.
