On small passenger vessels, how many supply and exhaust ducts are required in each enclosed space containing gasoline powered machinery or gasoline fuel tanks?

A 1 of each
B 2 of each
C 3 of each
D 4 of each
AI Explanation

The correct answer is B) 2 of each. According to the regulations set by the US Coast Guard, each enclosed space containing gasoline powered machinery or gasoline fuel tanks on small passenger vessels must have 2 supply ducts and 2 exhaust ducts. This ensures proper ventilation and air circulation to prevent the buildup of flammable vapors. The other options are incorrect because they do not meet the regulatory requirement of 2 supply and 2 exhaust ducts per enclosed space. Having fewer ducts would not provide adequate ventilation, while having more ducts is not necessary for compliance.
