All uninspected motor vessels constructed after 25 April 1940, which use fuel with a flash point of 110°F (43°C) or less, shall have at least what number of ventilator ducts for the removal of explosive or flammable gases from every engine and fuel tank compartment?
AI Explanation
The correct answer is B) 2.
This is because the regulation in 46 CFR 25.40-1 states that all uninspected motor vessels constructed after April 25, 1940, which use fuel with a flash point of 110°F (43°C) or less, shall have at least two ventilator ducts for the removal of explosive or flammable gases from every engine and fuel tank compartment.
The other options are incorrect because 1 duct would be insufficient, 3 ducts would exceed the minimum requirement, and 4 ducts would also exceed the minimum requirement specified in the regulation.
