Nautical Term: Inert Gas
Definition of Inert Gas
Inert Gas refers to a non-reactive gas, such as carbon dioxide or nitrogen, which is used to create an oxygen-deficient environment. This inerted atmosphere is beneficial in preserving the integrity of cargo and reducing the explosive potential of cargo tanks.
For instance, consider a cargo vessel transporting liquefied petroleum gas (LPG). The cargo tanks must be kept in an inerted state to minimize the risk of oxidation and subsequent explosion. To maintain this oxygen-deficient environment, the cargo tanks are regularly infused with inert gas, such as nitrogen.
