ABSTRACT:
The present invention relates to a waste fire suppression control device which is attached to the base of a conventional garbage chute system. The device comprises and incorporates a sequence of two control doors. One door is a main control door which is pivotally mounted at the base of the device and which is biased towards a closed position. The main control door opens only when the weight or force of garbage on the top surface of the door is greater than a pre-determined release force. The other door is a closing plate which is held open during normal operation of the device and closes either automatically in response to elevated temperature or manually. The two control doors together and separately form a barrier to prevent smoke and fire from entering the chute system and to contain smoke and fire within the dumpster area. As well, an integrated conventional sprinkler system floods the device and dumpster below with water.
