Abstract: An emergency exhaust system (59) is provided for a mobile incineration system (10). A hinged gate (76) controls access to the emergency exhaust system (59), and operates only upon the sensing of a malfunction in one of a plurality of critical incineration system components (114, 36, 56) by sensors/relays (122-126). A malfunction as sensed by Sensors/relays (122-126) causes the power to be cut through switch (98) to the main incineration system components (114, 36, 56, 46, 116, 118, 22). In a preferred embodiment, the emergency exhaust system (59) comprises a plurality of water sprayers (64) to cool the volatile waste combustion products, and a granulated activated carbon column (68) to remove hazardous substances.
