A Theoretical Approach to the Problem of determining the Relationship between the Constants of Circuits and their Intrinsic Safety

Abstract

THERE is an urgent need for a comprehensive theoretical correlation between the constants of a complex circuit and its intrinsic safety in the presence of inflammable gases. This has not yet been attempted owing to the lack of knowledge of the fundamental mechanism of spark ignition. I believe, however, that even in the present state of knowledge it is possible to derive a circuit theory which would permit the approximate correlation between intrinsic safety and circuit constants however complex the circuit may be.
