United States: industry on the ground
The Permian also yields potash, mined by the room-and-pillar method in Lea and Eddy counties in New Mexico, which adds mining and mineral-dust hazards to the oil and gas activity.

WhereUnited States
Short answer. An explosion proof mobile phone for United States cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

United States: rules and approvals
For Zone approval the ANSI/UL and ANSI/ISA 60079 series apply, and ordinary-location electrical safety standards such as ANSI/UL 61010 must also be met.
United States: geography and layout
The Permian Basin in West Texas and south-eastern New Mexico covers more than 86,000 square miles and extends about 250 miles wide and 300 miles long, so sites are spread over a very large area.
United States: industry on the ground
The Permian is the highest-producing US oil field, averaging 4.2 million barrels of crude a day in 2019, with Midland, Odessa and San Angelo serving as headquarters towns.
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 United States. Explosion-proof is the standard American phrase, and in the US it traditionally points to a heavy enclosure of the kind used in Class I Division 1 locations. The IS-04Z1 takes a different route, using intrinsic safety to limit the energy of a handheld. Reviewers at a refinery or LNG plant should ask which concept is meant.
The route · supply
Sourcing the IS-04Z1 for United States
Supply of the IS-04Z1 to United States starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · United States
Frequently asked questions
Can we buy an explosion proof mobile phone in United States today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an explosion proof mobile phone in United States cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which sites in United States does this cover?
The market guide for United States covers Permian Basin, Houston Ship Channel, Beaumont and Port Arthur, Lake Charles and Calcasieu, among others. Site-level pages are linked below.
How will SAMS supply United States?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What conditions affect devices in the Permian Basin?
The basin is dry and sparsely built, so summer heat, dust and long drives between sites are typical. Check the operating temperature range, dust ingress rating and battery life, and confirm any operator-specific site rules, including permits and gas detection practice, with the company controlling the lease.
What FCC approval does a smartphone need in the United States?
Radio-containing devices such as phones normally need FCC equipment authorisation, either by certification through an approved body or a supplier's declaration depending on the device type. Check the FCC rules and consult an accredited test lab or telecommunication certification body for your product's category.
Does the handset cover Class II dust areas in the US?
The Zone 21 design target covers dust at sulfur handling, coal transfer and solids charging, but certification is in progress and no listing exists. Check which Class and Division the final listing covers against your facility's own classification before use.
