The method is for continuously producing compressed-air foam, notably for fire fighting or for decontamining, by supplying both compressed air and a mixture of water and at least a foaming agent to a foaming chamber (5) outpu tting foam to a nozzle (9) via a pipe (8). The mixture of foam agent and wat er and the compressed air are each continuously supplied to the foaming cham ber (5) at a constant pressure and at a constant volume flow rate, e.g. by m eans of pressure regulators (1, 2) and of flow rate regulators (3, 4). The f oam pressure is regulated at the outlet of the foaming chamber (5) for maint aining the foam mixing pressure in the foaming chamber constant, preferably by a self-operating valve (6). The foaming chamber can advantageously be of a static type comprising sieves.
