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 Texas oil and gas fields. Zone 1 work arises at wellsites, tank batteries, drilling rigs, compressor stations and gas plants. Operators classify their own sites, and the Railroad Commission of Texas oversees oil and gas exploration, production and transport. SAMS does not classify areas or act as a regulator.

Questions · Texas Oil Fields
Frequently asked questions
Can we buy a hazardous area mobile phone in Texas Oil Fields today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does a hazardous area mobile phone in Texas Oil Fields 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 areas at Texas oil and gas fields would use it?
Likely candidates are wellsites and tank batteries, drilling rigs, compressor stations, gas processing plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Texas oil and gas fields?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Texas oil and gas fields.
Which authority regulates oil and gas operations in Texas?
The Railroad Commission of Texas regulates oil and gas production, pipelines and LPG safety, while each operator sets its own electrical safety and equipment rules. For equipment approvals, ask the operator which marks and standards they accept.
Which hazardous-area system is common in Texas?
US sites commonly use the National Electrical Code, which includes both a Class and Division approach and a Zone approach, and equipment is typically tested by a recognised US laboratory. The operator's area classification is the deciding document.
Do older and newer Texas fields need different checks?
Classification is site-specific, whatever the field's age. A wellsite, tank battery, compressor station or gas plant each has its own classification and drawings. Compare the IS-04Z1 target marking against each, and ask the operator about permit rules. Certification is still in progress.
