Which statement about the pressure in a tank being inerted by an inert gas system is TRUE?

A A positive pressure should be maintained at all times.
B The pressure must remain within the limits of +5 psi to -1 psi.
C The maximum pressure permitted is 8 psi.
D None of the above
AI Explanation

The correct answer is A) A positive pressure should be maintained at all times. This is because when a tank is inerted by an inert gas system, it is critical to maintain a positive pressure inside the tank at all times. This helps prevent the ingress of oxygen, which could create an explosive atmosphere. The regulations require that a positive pressure be maintained to ensure the integrity of the inerting system and the safety of the vessel. The other options are incorrect because they do not accurately reflect the regulatory requirements for inerted tanks. Option B specifies a pressure range that is too narrow, while option C sets an arbitrary maximum pressure that is not based on the regulations.
