Question 1 of 27070

🔍 Key Concepts

• Inert gas system (IGS) requirements for tankships carrying certain oxidizing cargoes like hydrogen peroxide • The purpose of maintaining a slight positive pressure in cargo tanks during discharge • Differences between atmospheric pressure, very low positive pressure, and higher positive pressures in psig

💭 Think About

• What could happen if the tank pressure were allowed to drop below a small positive pressure while discharging a reactive cargo like hydrogen peroxide? • Which of the listed pressures seems designed to keep air out without overstressing the tank structure or causing problems with venting? • How do typical inert gas system operating pressures on tankers compare with 5.0 psig, 3.0 psig, and 0.5 psig?

✅ Before You Answer

• Verify which option reflects a small but clearly positive pressure used to prevent air ingress, not just "normal" atmospheric conditions • Consider whether 5.0 psig or 3.0 psig is unusually high for routine tank inerting pressure during discharge • Remember that the chosen value must be consistent with standard IGS tank overpressure limits and safe operation on tankships
