ABSTRACT:
A storage tank such as those used to store petroleum products has a floating roof for the top closure and a seal between the roof and the tank sidewall for sealing the space and allowing relative movement therebetween. A conduit system is provided for the delivery of foam to the seal area in the event of a fire so as to extinguish the flame which is normally present in the seal area. The foam delivery system includes a conduit which preferably is flexible and functions both as a roof drain conduit and a foam delivery conduit which by a valve mechanism selectively allows draining of water from the roof or the delivery of foam to the roof.
