PCT No. PCT/AU91/00099 Sec. 371 Date Oct. 28, 1992 Sec. 102(e) Date Oct. 28, 1992 PCT Filed Mar. 19, 1991 PCT Pub. No. WO91/14477 PCT Pub. Date Oct. 3, 1991.A system for generating fire-fighting foam whereby a foam-forming chemical is mixed with water and air to form foam. The foam is pressurized preferably by the provision of pressurized air to force the foam out of a duct within which the foam is formed and to direct the foam at the seat of the fire or to the site to be protected against fire. A metal mesh is rotatable and preferably helical with respect to the direction of travel of the foam which acts as a catalytic agent and helps to clear foam from the duct within which the foam forms.
