Question 1701Deck General70% to pass
Backfire flame arrestors are installed on _______________.
AI Explanation
The correct answer is A) carburetors.
Backfire flame arrestors are installed on carburetors to prevent flames from entering the carburetor and potentially igniting fuel vapors, which could cause an explosion or fire. This is a safety requirement for vessels as per Coast Guard regulations.
The other options (B, C, and D) are incorrect because backfire flame arrestors are not typically installed on distributors, spark plugs, or fuel tanks. These components are not directly exposed to the risk of backfire that carburetors face, so the requirement for flame arrestors does not apply to them.
