Ex-Proof Smartphone in US LNG Terminals
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. Zone 1 and Zone 21 areas arise at liquefaction trains, storage tanks, loading arms and gas compression. If you are specifying an Ex-proof smartphone for US LNG export terminals, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Conditions in US LNG export terminals that affect handheld equipment
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.

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: 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.
US LNG export terminals: climate and equipment wear
LNG is held at about minus 162 degrees Celsius and is not itself flammable; it must first vaporise and mix with air in a range of roughly 5 to 15 percent before it can burn.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In US LNG export terminals. A marking check at a liquefaction train or ship loading berth would compare zone, gas group and temperature class with the terminal's drawings. The IS-04Z1 target is II 2 G Ex ib IIC T4, aimed at Zone 1 gas. The terminal operator, not SAMS, determines which gas group applies to methane-rich areas.

Specifying an Ex-proof smartphone 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 an Ex-proof smartphone in US LNG Terminals today?
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.
What does an Ex-proof smartphone 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
