The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Bakken, North Dakota (Williston Basin). On the Bakken, explosion-proof is the field shorthand for gear around rigs, wellsites, tank batteries and gas gathering. The protection concepts are different: flameproof Ex d contains an explosion, intrinsic safety prevents one. The IS-04Z1 is designed for intrinsic safety, with an Ex ib marking as the target.

The North Dakota Department of Mineral Resources, Oil and Gas Division oversees oil and gas activity. It does not approve phones. Equipment requirements generally come from operators and field service contractors, and SAMS holds no certificate yet, so ask the relevant operator what it would accept.
