The invention relates to a method for inerting a wall of a sealed and thermally insulating tank (1), said tank being intended to contain a liquefied fuel gas, wherein the wall has a multilayer structure comprising two sealed barriers (2, 4) and a thermally insulating barrier (3), said method including: implementing a first inerting mode in which the gaseous phase of the thermally insulating barrier (3) is placed under a relative pressure which is lower than a pressure limit of inflammability Pi of the fuel gas; detecting, during the first inerting mode, whether the pressure of the gaseous phase of the thermally insulating barrier (3) exceeds said threshold pressure Ps; and switching from the first inerting mode to a second inerting mode, the second inerting mode including sweeping the thermally insulating barrier (3) with an inert gas.
