Scale
The United States shipped 11.9 Bcf a day of LNG in 2024, with Louisiana's four terminals handling three-fifths. Cheniere reports 16 trains in operation across Sabine Pass and Corpus Christi.
The United States exports LNG mainly from Gulf Coast terminals in Louisiana and Texas. Zone 1 and Zone 21 areas arise at liquefaction trains, storage tanks, loading arms and gas compression. This page explains what to look for in an intrinsically safe mobile phone for US LNG export terminals, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for US LNG export terminals: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | US LNG export terminals: Liquefaction trains, LNG storage tanks, Ship loading berths | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in US LNG Terminals. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The United States shipped 11.9 Bcf a day of LNG in 2024, with Louisiana's four terminals handling three-fifths. Cheniere reports 16 trains in operation across Sabine Pass and Corpus Christi.
Cameron LNG has three trains of about 12 mtpa. Calcasieu Pass has 10 mtpa nameplate capacity and began commercial operations on 16 April 2025. Freeport LNG is in Freeport, Texas.
Golden Pass LNG at Sabine Pass, owned 70 percent by QatarEnergy and 30 percent by ExxonMobil, has an 18 million tonne a year capacity and was due to be commissioned in 2025.
By 2023 the US had become the world's biggest LNG exporter, with Cheniere, Freeport LNG and Venture Global as the largest exporters, and exported about 4.3 trillion cubic feet that year.
US Department of Energy records list export and re-export applications for projects including Cameron LNG, Port Arthur LNG Phase II, Sabine Pass Liquefaction, Golden Pass and Corpus Christi Liquefaction.
LNG developments sign long-term sales contracts, typically for 20 to 25 years, before investors commit, so sites operate for decades and equipment standards stay stable.
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 US LNG export terminals. LNG operators run inspection rounds across trains, storage tanks, loading berths and compression. A handheld intrinsically safe phone is designed to be carried into those Zone 1 areas for notes, photographs and field messaging. Commissioning of new capacity also draws many contractors; certification must be complete before any classified use.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are liquefaction trains, lng storage tanks, ship loading berths, gas compression and pipelines. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Export terminals run continuously, with ships loading regularly and trains shut down only for planned maintenance. Teams visiting for service or inspection need to coordinate with operations and book access well ahead.
Several US LNG sites named in federal filings, including Sabine Pass, Cameron and Corpus Christi, are on the Gulf Coast, where storm season makes shutdown and evacuation planning normal. Keep spares and agree storm-season support arrangements with the operator.
Not automatically. Each terminal has its own classification drawings and approval process, so a marking accepted at one may need separate review at another. The IS-04Z1 target is II 2 G Ex ib IIC T4, and certification is in progress. Ask each operator what documents it expects.
