Question 1318 Deck General

The correct answer is A) purging. Purging refers to the process of introducing an inert gas, such as nitrogen or carbon dioxide, into a tank that is already inert with the goal of further reducing the oxygen or hydrocarbon content. This is done to prevent the risk of combustion if air were to enter the tank. The other options are incorrect because: B) Gas dispersion refers to the process of distributing the inert gas throughout the tank, which is a part of the purging process. C) Bonding is the electrical connection between different metal components to prevent static electricity buildup, which is a separate safety measure. D) Gas freeing is the process of removing all flammable vapors from a tank to make it safe for entry.
