Question 790Deck General70% to pass
Your tankship is carrying a 30% solution of hydrogen peroxide. The cargo containment system must have a permanent inert gas system. While discharging this cargo the inert gas system must maintain a minimum pressure of _______________.
AI Explanation
The correct answer is B) 0.5 psig.
The requirement for the minimum pressure of the inert gas system during the discharge of a 30% hydrogen peroxide solution is specified in 46 CFR 153.500(b), which states that the inert gas system must maintain a minimum pressure of 0.5 psig in the cargo tank. This is to ensure that the cargo tank remains under a slight positive pressure to prevent the ingress of air, which could potentially lead to a hazardous situation.
The other options are incorrect because: A) 3.0 psig is too high, C) atmospheric pressure is not sufficient to maintain the required positive pressure, and D) 5.0 psig is also too high.
