1. A gas-arrestor system that facilitates termination of an ignitable portion of a gas burning device comprising:

  • at least two sensing resistors arranged in parallel within a power circuit, wherein the at least two sensing resistors are heated and adsorb oxygen on their surfaces to yield a build up of resistance and an isolation barrier between the resistors during normal operation of the gas burning device, and wherein the at least two sensing resistors detect at least one kind of gas at a specific concentration level by way of their voltage output; and

    a decision component that measures the voltage output from the at least two sensing resistors to determine whether the voltage output correlates to a calibrated level below a lower explosion limit of at least one specific gas at a specific concentration,characterized in that when the voltage output indicates the presence of at least one specified gas at a prescribed concentration, the at least two sensing resistors are shorted, thereby terminating power from the power circuit.
