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 Baytown, Texas (ExxonMobil Baytown complex). A complex covering about 3,400 acres means long walks between units, so a handheld that works in classified areas saves return trips. Intrinsic safety suits cracker, refinery and storage rounds, and the project inspections linked to the blue hydrogen facility, where crews photograph and record findings on the spot.
