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).

Intrinsically Safe 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. If you are specifying an intrinsically safe smartphone for Louisiana, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereLouisiana
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Louisiana: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Site conditions at Louisiana: what wears and what limits 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: 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.
Louisiana: geography and layout
The Mississippi River runs about 600 miles through the state to the Gulf, and the low alluvial coastal region of swamp, marsh and barrier islands covers around 12,350 square miles.
Louisiana: industry on the ground
Chemical products and petroleum and coal products are among the main contributors to Louisiana's gross state product, alongside food, transport equipment and paper.
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Louisiana. Louisiana's 15 refineries and four LNG export terminals run frequent rounds, inspections and turnarounds. A handheld intrinsically safe phone is designed to be carried into Zone 1 areas for notes, photographs and messaging at those tasks. It does not remove the need for the operator's permit system, and certification must be completed first.

Specifying an intrinsically safe 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 intrinsically safe 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 intrinsically safe smartphone in Louisiana 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 does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
