Starting motors, generators, and any other spark producing devices shall be __________. (small passenger vessel regulations)

Correct Answer: Option B — mounted as high as practicable above the bilges

46 CFR 183.340 requires that spark-producing devices, such as starting motors and generators, be mounted as high as practicable above the bilges. This placement minimizes the risk of these components igniting gasoline vapors that may have settled in the lower, poorly ventilated areas of the vessel's engine space.
