Question 1115 Deck Safety

You are correct, the statement "Fuel vapors gather in the lowest portions of the vessel" is the true statement concerning fuel vapors on a vessel. This is because fuel vapors are heavier than air and will naturally accumulate in the lowest areas of the vessel, such as the bilge. This can create a dangerous situation if an ignition source is present, as the fuel vapors can easily ignite. The other options are incorrect because: A) Vent outlets should be located above the level of the fuel tanks, not the carburetor intake; C) Fuel vapors can be ignited by any ignition source, not just an open flame.
