The explosion proof mobile phone requirement for US LNG and midstream work comes down to two kinds of site: Gulf Coast export terminals, and the compressor stations and gas plants that feed them. This page is for terminal operators, pipeline owners and the contractors who service them. For one operator’s terminals, see our page on an explosion proof phone for Cheniere. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
FERC’s export map from March 2026 lists Sabine Pass in Louisiana, Cameron LNG at Hackberry, Freeport in Texas, Calcasieu Pass in Cameron Parish, Cove Point in Maryland and Elba Island in Georgia as operating terminals, with Plaquemines in Louisiana and Golden Pass in Texas the large projects still in construction or start-up. Golden Pass produced its first LNG on 30 March 2026, with QatarEnergy holding 70 per cent and ExxonMobil 30 per cent. Upstream of the terminals is the midstream chain: gathering lines, gas processing plants and compressor stations. In the Delaware Basin, Enterprise has built a series of Mentone natural gas processing plants, and in Appalachia, processing of Marcellus and Utica gas runs to several billion cubic feet a day. The common feature is a small crew supervising a large classified footprint, which is exactly the situation where an Ex handset earns its place.
LNG terminals and midstream stations share one operating pattern: small crews, large classified areas and contractors who rotate between jobs.
A compressor station may be unstaffed between visits. Four-constellation GNSS, a clear camera and Android 16 let a technician log what was found, where and when, in a form the control room can open immediately.
Terminals such as Golden Pass and Plaquemines draw a large pool of commissioning contractors. A managed fleet with centralised enrolment keeps device policy consistent while the workforce changes.
A terminal built under an international EPC contract may carry IECEx or ATEX documentation while an older US station is drawn in Class and Division terms. The IS-04Z1 is being certified to IECEx, ATEX and NEC 500 so paperwork exists for each.
Appalachian winter and Gulf summer are both part of one fleet’s year. IP68 sealing and rugged build are the design answer, and temperature class still has to be checked against each area.
These are generic questions, not a description of any operator’s registration programme, which we have not verified.
No device enters a classified area before its listing and certificates exist. Pre-launch, what can be shared is the datasheet and a written certification schedule.
Ask the operator’s IT team which console administers field devices and whether the handset must work with its existing Android Enterprise setup.
Decide who issues devices on an EPC site and what happens to data on them when the job finishes.
Not yet. IECEx, ATEX and NEC 500 certification are in progress ahead of a Q4 2026 launch, and no certificate has been issued. SAMS has no supply relationship with any named terminal.
Rarely for the liquefaction process itself, but compressor station and utility areas, and some construction work, can raise dust questions. The Zone 21 design target means one device is aimed at both, subject to each area classification.
This one covers the sector across terminals and midstream. The Cheniere Energy page goes through Sabine Pass and Corpus Christi site by site.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for United States. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
