Float means are formed in sections so that they may be secured together to surround a fire in a water covered area. Nozzle means are mounted on the float means and are communicated with conduit means through which water may be supplied and ejected from the nozzle to provide a water shield for enclosing the flame and cutting off its oxygen supply. Barrier skirt means are secured to the float means to depend downwardly therefrom into the water covered area to trap contaminant floating on the water, and additional conduit means are carried by the float means with an open end projecting on one side of the barrier skirt means for communication with the contaminant floating in the water so that the contaminant may be sucked through such conduit means and discharged into a container to avoid pollution.
