A fire tool consists of a nozzle section having a penetrator section at the end and an attachment section at the bottom for attachment to an extensible hydraulic ram. The ram has a base adapted to be secured to a horizontal surface such as the deck of a ship next to a vertical surface such as a bulkhead in such ship and the entire unit is leaned against the bulkhead with a specially designed point against such bulkhead. The hydraulic ram is then activated to force the tip of the penetrator into the bulkhead and ultimately through the bulkhead, after which water may be sprayed into the area behind the bulkhead where a fire may be burning through spray orifices in the nozzle section, the water being injected into the nozzle section through a fitting on the opposite side of the bulkhead from the spray orifices. The arrangement of the fire-fighting tool at an angle between the deck and the bulkhead assures that there will invariably be a rigid surface available for enabling pressure of the hydraulic ram to be exerted forcefully enough on the end of the penetrator section to breach the wall or bulkhead. The point of the penetrator is designed so that it will dig into the wall surface efficiently and effectively even though it is applied to such wall surface at an angle. |
