ABSTRACT:
Devices for constraining wildfires are disclosed. The first device is a free-standing hollow structure which contains at least one lower intake duct, a vertical duct, and an upper outlet duct. This device contains curved chambers which may have baffles. This device also provides an open container for the delivery of water to the fire in the form of steam. A second device is a free-standing structure which is anchored to the ground by lines attached to spikes and supporting legs. The upper portion of the device is curved toward the fire so as to direct the fire back upon itself. There is an arcuate baffle at approximately the midpoint of the device which serves to break up the heat wave. A third device is similar to the second device in design, but is made of folding sections for ease of storage and transportation. A fourth device comprises a fire-resistant sheet which may be draped over trees or structures or may be put on the ground to form a barrier to the fire. A plurality of these devices may be aligned at the perimeter of a fire to establish a barrier to constrain the fire or may be placed around real or personal property to protect that property. A fifth device is a fire-resistant sheet which may be stored as rolls and joined with other sheets to form a barrier. One type of device may be used alone, or as many as all five types may be used in combination.
