The invention relates to a method for operating a plant () for on-site production of medical gas, such as air or oxygen, comprising a main gas line () comprising, in series, a first vessel (A) for storing gas and a second vessel (B) for storing purified gas, and a secondary line () fluidically connected to the main line (), downstream of the first vessel (A) for storing gas, and comprising a third vessel (C) for storing gas, the main gas line () and the secondary line () each supplying at least one gas consumer site (), in particular a network of pipes in a hospital. 1100. An on-site medical gas production plant () , comprising:{'b': '50', 'a gas purification unit () adapted to produce a purified gas from a supply gas,'}{'b': 10', '10, 'a main gas line () supplied with a gas by the gas purification unit () and comprising, in series, a first vessel (A) for storing a less pure gas and a second vessel (B) for storing a purified gas, and'}{'b': 20', '10, 'a secondary line () fluidically connected to the main line (), downstream of the first vessel (A) for storing the less pure gas and comprising a third vessel (C) for storing gas,'}{'b': 1', '2, 'at least one gas analysis device (D; D) arranged so as to determine the level of at least one given impurity in the gas, downstream of the second (B) and third (C) vessels,'}{'b': 1', '10, 'a first solenoid valve (V), arranged on the main gas line () between the first vessel (A) for storing the less pure gas and a second vessel (B) for storing the purified gas,'}{'b': 3', '20, 'a second solenoid valve (V), arranged on the secondary gas line () between the first vessel (A) and the third vessel (C) for storing gas,'}{'b': 2', '10, 'a third solenoid valve (V), arranged on the main gas line () downstream of the second vessel (B) for storing the purified gas,'}{'b': 4', '20, 'a fourth solenoid valve (V), arranged on the secondary gas line () downstream of the third vessel (C) for storing gas, and'}{'b': 4', '1', '4', '1', '2, 'an ...
