what is inerting in confined space
Pure oxygen must not be used to ventilate a confined space. What is inerting? Inerting is a special form of purging and ventilating. Inerting involves purging oxygen from a confined space using an inert gas (such as nitrogen, carbon dioxide or argon) to remove the hazard of fire or explosion. The concentration of oxygen is decreased to below the level that can support combustion.
