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).

Industrial Mobile Phone 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. If you are specifying an industrial mobile phone for Louisiana, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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.
Field notes · Louisiana
More about Louisiana that matters for portable equipment
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.
Louisiana: climate and equipment wear
Southern Louisiana has long, hot, humid summers, with highs averaging 90 degrees Fahrenheit or more from June to September and overnight lows above 70, and frequent brief tropical downpours.
Louisiana: geography and layout
The state sits at the junction of the Mississippi River system and the Gulf of Mexico, with the Gulf no more than about 200 miles from any point.
Louisiana: industry on the ground
Louisiana has 14 operable refineries with about 3.0 million barrels a day of crude capacity, around 17 percent of the US total and second only to Texas.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Louisiana. A contractor working across Louisiana may move from a refinery to an LNG terminal in the same month. A device built for EMM or MDM enrolment lets one fleet policy follow the crew. Charging stays in safe areas, and each plant's own connectivity and security rules decide what can be configured on site.

Specifying an industrial mobile phone 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 industrial mobile phone in Louisiana 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 industrial mobile phone 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 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
