Abstract: A fire prevention and extinguishing system and method designed to prevent and automatically extinguish Christmas tree fires. The system preferably includes a case containing a fire extinguisher, controls, a ground fault circuit interrupter (“GFCI”) receptacle, a strobe light and a siren. A cable having heat sensors is connected to the case. The cable has a length sufficient to enable the heat sensors to be positioned throughout the Christmas tree. A hose is connected to the fire extinguisher and includes a portion which is positioned in the tree. The system is powered via 110 vac. Christmas light strings are plugged into the GFCI receptacle which automatically shuts off the power upon detection of an electrical short in the light strings, thereby preventing the occurrence of an electrical fire. Upon the occurrence of a tree fire, the heat sensors immediately detect the fire and activate the automatic fire extinguishing portion of the system.
