The most common gas used for inerting, purging and blanketing is nitrogen, due to its cost effectiveness, ease of production and relative safety. It is so common, the processes are also known as nitrogen inerting, nitrogen purging and nitrogen blanketing respectively. Other typical gases include nitrogen enriched air, carbon dioxide and argon.

strategic locations of a the mine to better isolate the combustion area and enhance and ensure the inertisation process (Gray et al., 2004; Trevits et al., 2005). Depending on where the combustion event is located in the mine, the use of inertisation techniques in mine emergencies often presents a major challenge to control and evaluate the ...

Inert gases are non-combustible gases (also called protective gases) which do not react with the fuel and do not promote combustion. In inertization, the inert gas displaces the atmospheric oxygen in the plant to such an extent that an explosive atmosphere is prevented. As a rule, nitrogen is used as the inert gas.
