AbstractA fire curtain constituted by two nets of nonflammable material is stored in a container on the ceiling and hangs therefrom as soon as a fire starts. Simultaneously, a mixture of water and a bubbling agent in the form of fine bubbles is flown down the curtain to check the spread of flame and smoke. Any section where a fire starts can be isolated from neighboring sections by means of a plurality of such fire curtains. Made of soft, flexible material, the curtain used neither injures a person upon closure nor prevents him from escaping to safer places.
