70% to pass

What is the maximum allowable oxygen content within the ships cargo tanks, inert gas piping and the vapor recovery system?

A 4%
B 5%
C 8%
D 10%
AI Explanation

The correct answer is C) 8%. The maximum allowable oxygen content within the ship's cargo tanks, inert gas piping, and the vapor recovery system is 8%. This is a regulatory requirement set by the International Convention for the Safety of Life at Sea (SOLAS) and enforced by the US Coast Guard for vessels operating under a Captain's License. The reason 8% is the correct limit is that it provides a safe margin to prevent the cargo vapor from reaching the flammable range and reducing the risk of explosions or fires. The other answer choices of 4%, 5%, and 10% are not the correct regulatory limits for these shipboard systems.
