Question: 1 / 1030

What should be used to inert an integral fuel tank before repairs?

Nitrogen

Oxygen

CO2

Integral fuel tanks are typically inerted with carbon dioxide (CO2) before any repairs are conducted. Inerting the fuel tank with CO2 helps prevent the possibility of fire or explosion during maintenance activities. This is achieved by displacing the oxygen within the tank with CO2, as oxygen is a necessary component for combustion to occur. Using nitrogen, oxygen, or helium for inerting the fuel tank can introduce safety risks due to their potential to support combustion.
