Features: The Lightweight Decontamination System is a compact, lightweight, portable decontamination system. It consists of a 7.3 horsepower engine, a self-priming pump for drawing and pressurizing water, a fan assembly to deliver combustion air to the heater, a water heater with a coil of tubing 90 feet (27.45 meters) long, a self-priming pump for the heater fuel system, and a small generator to supply electricity for ignition and safety control functions. The LDS is transportable by 3/4-ton trailer, 5/4-ton cargo trucks, cargo aircraft, and helicopters (sling load).
The LDS provides pressurized water at temperatures up to 248 degrees Farenheit (119.88 degrees Centigrade) at a rate of up to 9 gallons (34.06 liters) per minute. It draws water from a natural source up to 30 feet (9.15 meters) away and 9 feet (2.75 meters) below pump level. There is an additional 3000 gallon (113.55 hectoliter) water storage tank in the event a natural source of water is not available. The system is salt-water resistant.

Inventory: 1287 are currently fielded. The acquisition objective (AO) is 1449. 1221 (84 percent) of the AO is funded and will be met by FY 95.
