The invention relates generally to the art of self-contained heating devices and in particular to portable heating devices employing chemical reaction to produce heat. Currently, hand-held heat sources, capable of producing heat at a sufficiently high temperature to activate heat-shrink material, rely on either the combustion of flammable material or electrical power to provide energy for generating the required heat. An object of the present invention is to provide a portable device capable of providing sufficient heat to shrink heat-shrinkable tubing. A further object of the invention is to provide a non-flammable heat source suitable for use in the presence of explosive atmospheres. Still another object of the invention is to provide a portable hand-held device for generating heat which can be directed to a specific location on a work surface. Patent applications. JES
