Abstract: A portable, pallet-mountable, remotely controlled deluge system provides a means for rapidly delivering a large quantity of a liquid to a region of hazardous materials or a fire. An accumulator, mounted, for example, on a pallet is charged with a quantity of water, aqueous film-forming foam, or other liquid quenching agent. The liquid is pressurized with an inert gas and the liquid is held in the accumulator by an electric/hydraulic valve. The valve is connected to a control panel which is wired to a remote control. The control panel also includes an antenna to receive a remote control signal by electromagnetic communication. The system provides a method of quickly getting a fire-fighting liquid or a deluging liquid to a scene of a fire or a hazardous waste spill without subjecting personnel to the hazard.

Abstract: The present method and apparatus are directed to a fire control system for use with a drilling rig. Multiple nozzle means are positioned around a drilling rig at selected locations to spray water delivered through fire hoses onto the rig to prevent fire damage. The equipment utilizes a skid-mounted engine and connected centrifugal pump for delivery of water from a closed storage tank. An engine control unit adjusts the throttle to an operating speed which delivers no water during normal operation. Subject to control by switch means on the rig floor, either hard wired or by means of a radio transmitter and receiver arrangement, the engine control unit switches the engine to maximum power output. An alarm is also sounded when this occurs. So long as the engine is running, operating lights signal rig personnel that the equipment is operative. The equipment is switched from a slow speed operation to a maximum power output to deliver water under control of rig personnel.
