A flashback precluding torch is attachable to an aerosol propane canister containing propane gas under pressure and has a fixture receiving fitting. The flashback precluding torch comprises an elongate hollow main body member having an anchored end and a free end, a gas flow inlet disposed at the anchored end, a gas flow outlet disposed at the free end, and a gas flow passage connecting in fluid communication the inlet and the outlet. An attachment mechanism is provided for removably attaching the anchored end of the elongate hollow main body member to the fixture receiving means of the aerosol propane canister. A manually operable main valve is operatively mounted on the elongate hollow main body member. A flame directing nozzle is operatively mounted on the main body member at the free end. A safety flow valve is operatively mounted on the elongate hollow main body member, so as to control the flow of propane through the elongate hollow main body member.
