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 Bakken, North Dakota (Williston Basin). Technicians in western North Dakota travel to remote wellsites and tank batteries for gauging, checks and records. A handheld intrinsically safe phone is designed to be carried into those Zone 1 areas. Cold weather affects batteries, so low-temperature handling matters, and certification must be finished before use in classified areas.
