A reactor system that can safely use general purpose electrical devices and unregulated surface temperature heat sources even though a flammable and/or combustible substance is being processed in the reactor or is within the processing area. The reactor system includes a reaction vessel and at least one process control device proximate the reaction vessel which is a possible ignition source for flammable and combustible materials. A shroud encloses the ignition source within a chamber and the chamber is provided with an inactive environment which is effective for preventing the ignition source from igniting any flammable or combustible substance that may enter the chamber.
