ABSTRACT:
A open air fire quencher comprises a vessel having a substantially airtight top and sides and at least a partially open bottom. The open bottom permits placement of the vessel vertically down over a flame source until the bottom rests on a grade surrounding the flame source. The vessel includes an inner quenching chamber and an outer chamber. The outer chamber may be filled with water to absorb the thermal energy from the flame source. The outer chamber includes a drain to allow water to be released downward. The released water assists in forming an airtight seal around the open bottom. The released water further assists in cooling the area surrounding the flame. In a further embodiment the inner chamber has a flame deflector and the vessel includes an extinguishing system for spraying the flame source with an extinguishing substance.
