The use of a composition comprising at least one perfluoroalkane and at least one hydrofluoroalkane is proposed to replace extinguishing agents such as trifluorobromomethane and difluorobromochloromethane. The composition, optionally pressurised with an inert gas, can be employed for the protection of premises by the so-called total-flooding technique.
