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.

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 · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In United States. US classified areas range from the Permian and Williston basins to the Houston Ship Channel, Beaumont, Lake Charles, Baton Rouge, Corpus Christi, the Alaska North Slope and the deepwater Gulf. The operator or owner classifies each location. SAMS does not classify any area and designs only for a stated one.
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 a hazardous area cell 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 a hazardous area cell 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
Is IECEx or ATEX certification enough for US hazardous locations?
Not on its own. US workplace rules accept equipment approved by an OSHA-recognised NRTL and marked accordingly, and ATEX or IECEx certificates are not accepted in their place. Manufacturers usually need a separate US listing, so check the NRTL mark and the Class, Division or Zone marking on any device.
Do US sites use Class and Division or Zone classification?
Both exist. Article 500 of the National Electrical Code defines the Class and Division system, and Articles 505 and 506 define Zones. Many existing refineries and gas plants are still classified by Division, so confirm which system the area drawing uses before selecting equipment markings.
Can one handset suit both a Permian wellpad and a North Dakota gas plant?
IP68 sealing and a rugged build are aimed at August heat and January cold, and the 4,000 mAh battery at a shift away from the truck. The approved ambient range will come from the certificate, which is in progress, so confirm it for both extremes.
