Refining
The 15 refineries can process almost 3 million barrels of crude a day, and three of them rank among the ten largest in the United States, according to the US Energy Information Administration (EIA).

ATEX and IECEx Smartphone in Louisiana
Louisiana has 15 oil refineries, about one-sixth of US refining capacity, plus a Mississippi River industrial corridor and four operating LNG export terminals. Zone 1 and Zone 21 areas arise at refinery units, petrochemical plants, LNG trains and storage across the state. This page explains what to look for in an ATEX and IECEx smartphone for Louisiana, and where the IS-04Z1 stands against that list today.

What Louisiana means for portable equipment
LNG
In 2024 the four operating Louisiana terminals handled three-fifths of US LNG exports. Sabine Pass is the largest US operating terminal, at about 35 per cent of national LNG exports.

More about Louisiana that matters for portable equipment
Louisiana: infrastructure
The stretch of river between New Orleans and Baton Rouge is home to more than 140 chemical plants and refineries, with new plants added where cheap natural gas meets international port access.
Louisiana: who works there
Other large refineries include Citgo at Lake Charles, Phillips 66 at Westlake, Shell at Norco with about 231,000 barrels a day, and Valero at Norco and Meraux.
Louisiana: who works there
The largest refinery in the state is Marathon Petroleum's Garyville plant at 617,000 barrels a day, followed by ExxonMobil's Baton Rouge refinery at about 523,500 barrels a day.
Louisiana: rules and approvals
Louisiana is divided into parishes rather than counties, so permits, local authorities and emergency planning bodies are organised at parish level.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Louisiana. Louisiana's refineries, Mississippi River corridor plants and LNG terminals include international owners and EPCs who often ask for certificate evidence that travels between countries. A dual ATEX and IECEx route is designed to meet that expectation for the IS-04Z1. Certification is in progress and no certificate has been issued, so evidence is a plan, not a document.

Specifying an ATEX and IECEx smartphone for Louisiana
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 · Louisiana
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Louisiana 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 an ATEX and IECEx smartphone in Louisiana cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Louisiana would use it?
Likely candidates are refinery process units, petrochemical plants, lng liquefaction and loading, tank farms and terminals. 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.
Where are Louisiana's main refining and chemical clusters?
They concentrate along the Mississippi River between New Orleans and Baton Rouge, around Lake Charles in the southwest, and in the Norco and Chalmette areas. Each has its own operators, so confirm the exact plant and gate procedures before sending staff or equipment.
What should I confirm with a Louisiana operator before bringing portable devices on site?
Ask for the area classification for the units you will visit, the equipment approvals they accept, and any rules on cameras, radios and charging. Requirements vary by operator, and your safety contact on site is the authority.
Is one approval enough for refineries and LNG terminals across the state?
Not necessarily. Operators set their own contractor and equipment approvals, so a refinery and an LNG terminal may ask for different documents. The IS-04Z1 has no certificate yet. Confirm requirements with the site operator for each plant before planning a fleet.
