question 4
what is the best way to check for gas fumes after fueling a pwc?
a smell for fumes.
b look for gas vapors.
c listen for a hissing sound.
d strike a match.

Explanation:

Smelling is a simple and common - sense way to detect gas fumes. Looking for gas vapors may not be effective as they are often invisible. Listening for a hissing sound indicates a leak in the fuel system rather than just fumes. Striking a match is extremely dangerous as gas fumes are highly flammable.

Answer:

A. Smell for fumes.
