Hazardous Area Mobile Phone in US LNG Terminals
The United States exports LNG mainly from Gulf Coast terminals in Louisiana and Texas. The Lake Charles LNG terminal near Lake Charles, Louisiana, has facilities for LNG receipt, storage and regasification and is one of the few such US terminals. This page explains what to look for in a hazardous area mobile phone for US LNG export terminals, and where the IS-04Z1 stands against that list today.

More about US LNG export terminals that matters for portable equipment
US LNG export terminals: projects and investment
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.
US LNG export terminals: background
Cheniere became the first US company to gain permission to export LNG, and its first exports came in 2016, after a long period in which terminals were designed for imports.
US LNG export terminals: industry on the ground
Cheniere's Corpus Christi site has net liquefaction capacity of 18 million tonnes a year and was reported running near its peak feed-gas rate, with expansion filed for four more trains.
US LNG export terminals: industry on the ground
In 2024 the United States had seven large LNG liquefaction export terminals with a combined capacity of about 88 million tonnes a year.
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 US LNG export terminals. The area types are liquefaction trains, LNG storage tanks, ship loading berths, and gas compression and pipelines, where Zone 1 and Zone 21 areas arise. Each terminal operator, such as Cheniere, Sempra or Venture Global, classifies its own site. SAMS has no role in classification.

Specifying a hazardous area mobile phone for US LNG Terminals
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · US LNG Terminals
Frequently asked questions
Can we buy a hazardous area mobile phone in US LNG Terminals 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 mobile phone in US LNG Terminals cost?
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.
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 US LNG export terminals would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Are LNG terminals busy all year?
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.
How do hurricanes affect Gulf Coast LNG sites?
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.
Does the same device record work for every US terminal?
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.
