Abstract

Intrinsic safety is the safest technique to prevent explosions that might occur in underground coal mines and process industries in the presence of explosive atmosphere. Designing of intrinsically safe equipment require keeping its energy below the minimum ignition energy of the explosive gases. In this work, three empirical relations based on standard IS/IEC 60079-11 have been proposed for the first time and used in the calculation of short circuit current (I), permitted capacitance (C) and inductance (L) of intrinsically safe circuits designed for gas groups IIA, IIB, IIC and I. The calculated values are compared with the available experimental and reported values. A fairly good agreement has been obtained between them. The designers of intrinsically safe circuits can use these relations as a very handy tool especially for the explosive gas atmosphere of underground coal mines and process industries. This research will contribute to the reduction of fatal accidents due to explosive gases.
