Question 1054 Deck General

The correct answer is C) they must be positive pressure. The requirement for ventilation spaces of a gas safe space within the cargo area is that they must be maintained at a positive pressure relative to the surrounding spaces. This ensures that any potential leaks would force air outward, rather than allowing gas to enter the gas safe space. This positive pressure ventilation system is a critical safety measure to prevent the buildup of flammable or toxic gases in these enclosed cargo areas. The other options are incorrect because they do not accurately describe the necessary ventilation requirements for these gas safe spaces.
