Abstract
A method of fighting a fire drives a first fire-extinguishing liquid from at least one spray head or sprinkler at a fire with a low-pressure pump. Thereafter it drives a second fire-extinguishing liquid from a liquid container and the spray head or sprinkler at the fire with a first propellant gas from at least one gas container, at least some of the first propellent gas remaining in the gas container after all of the second fire-extinguishing liquid has been driven from the liquid container. Still thereafter it again drives the first fire-extinguishing liquid from the spray head or sprinkler at the fire with the low-pressure pump, the low-pressure pump being driven by the first propellant gas that was remaining in the gas container.
