Answer:
Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.

hand portable or a wheeled fire extinguisher. Argon is used as the expelling gas for these extinguishers because lithium will react with nitrogen to form other combustible alloys. Other Class D Agents are available for specific Class D fuels and/or environments
Nitrogen gas has long been used in the fire suppression industry. Its primary use has been as a pressurization gas in total-flood fire suppression systems and in portable fire extinguishers
