Question 389 Deck General

70% to pass

The number of pounds of carbon dioxide required for each cargo space on a cargo vessel is equal to _______________.

A the gross volume of the space in cubic feet divided by 100
B one pound of CO2 per cubic foot of space
C one pound of CO2 per square foot of deck area
D the gross volume of the space in cubic feet divided by 30
AI Explanation

The correct answer is D) the gross volume of the space in cubic feet divided by 30. This is based on the regulation in 46 CFR 95.15-20, which states that the quantity of carbon dioxide required for each space is equal to the gross volume of the space in cubic feet divided by 30. This provides the amount of CO2 needed to displace the oxygen and effectively extinguish a fire in the cargo space. The other options are incorrect because A) dividing by 100 would provide an insufficient amount of CO2, B) one pound per cubic foot is not the regulatory requirement, and C) using the deck area rather than the volume is not the correct method specified in the regulations.
