Question 1100 Deck General
70% to passWhat percent of oxygen content by volume, must each inert gas system be designed to supply the cargo tanks with a gas, or mixture of gases?
A
15% or less
B
10% or less
C
20% or less
D
5% or less
AI Explanation
The correct answer is D) 5% or less. The International Convention for the Safety of Life at Sea (SOLAS) regulations require that inert gas systems be designed to maintain the oxygen content in the cargo tanks at 5% or less by volume. This low oxygen concentration helps prevent the risk of explosions and fires in the cargo tanks. The other answer choices are incorrect because 15% or less (A), 10% or less (B), and 20% or less (C) do not meet the SOLAS regulatory requirement of 5% or less oxygen content by volume for inert gas systems.
