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.

Hazardous Area 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. Chemical products and petroleum and coal products are among the main contributors to Louisiana's gross state product, alongside food, transport equipment and paper. This page explains what to look for in a hazardous area smartphone for Louisiana, and where the IS-04Z1 stands against that list today.

What Louisiana means for portable equipment
Climate
A subtropical, humid climate with the highest annual rainfall of the lower 48 states. Most refineries are in the south of the state and are exposed to storms.

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 · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Louisiana. Classified areas in Louisiana include refinery process units, petrochemical plants, LNG liquefaction and loading, and tank farms and terminals. Each operator, such as Cheniere, Sempra or Phillips 66, classifies its own areas. SAMS does not classify anything; it can only describe the marking and limits of its product.

Specifying a hazardous area 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 a hazardous area smartphone in Louisiana today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does a hazardous area smartphone in Louisiana cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
