Site conditions at Louisiana: what wears and what limits equipment
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).
Field notes · Louisiana
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 · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Louisiana. A marking check across Louisiana sites would compare zone, gas group and temperature class with each operator's classification, from refineries in the south to LNG trains on the coast. The IS-04Z1 target is II 2 G Ex ib IIC T4. Hydrocarbon applications may not need the widest gas group, but IIC gives margin and the operator decides.

Specifying an Ex-proof 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 Ex-proof mobile phone 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 an Ex-proof mobile phone 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
