The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Mathura, Uttar Pradesh. Rounds at product loading gantries, tank farms and pipeline pumping stations are routine and frequent, and truck movements add pressure to log quickly. An intrinsically safe handheld supports that work. The IS-04Z1 is designed for it, though certification is still in progress.
