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.

Explosion-Proof 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. 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. If you are specifying an explosion proof smartphone for Louisiana, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Local conditions · Louisiana
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.
Field notes · Louisiana
More about Louisiana that matters for portable equipment
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.
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Louisiana. Statewide, the term explosion-proof covers refinery units, petrochemical plants, LNG loading and tank farms in everyday speech. The engineering choices differ: flameproof Ex d contains a blast, while intrinsic safety prevents ignition by limiting energy. The IS-04Z1 is designed for the latter, with Ex ib as its marking target.

Specifying an explosion proof 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 explosion proof 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 explosion proof 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 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is 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.
