Refining
ExxonMobil's refinery dates from 1909 and has a reported capacity of 540,000 barrels a day as of 2020. It is among the largest in the US.
Baton Rouge is the Louisiana state capital on the Mississippi River. Its economy is anchored by petrochemicals, with ExxonMobil's refinery and chemical complex in the city and Dow operations nearby. Class I and Zone 1 areas occur at process units, tank farms and docks. An Ex-proof smartphone distributor in Baton Rouge would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Baton Rouge has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Baton Rouge. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

ExxonMobil's refinery dates from 1909 and has a reported capacity of 540,000 barrels a day as of 2020. It is among the largest in the US.
The Port of Greater Baton Rouge is the farthest inland point on the Mississippi that ocean-going vessels can reach, linking industry to rail, pipeline and barge.
About 6,300 people work across the sites, around 4,000 direct employees with the rest contractors, so contractor induction is a central part of site access.
ExxonMobil's Baton Rouge complex began with the refinery in 1909 and now includes the refinery, a chemical plant and several other plants and terminals along the Mississippi River.
The Port of Greater Baton Rouge is the northernmost Mississippi River port able to take Panamax ships, with its shipping channel kept at about 45 feet and jurisdiction covering roughly 85 miles of the river.
The refinery runs its own power plant, which supports continuous operation of the interconnected process units.
“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 Baton Rouge. A marking check at ExxonMobil's refinery would compare the operator's area classification with the equipment label, covering group and temperature. Refinery and chemical units may involve hydrogen or ethylene, so IIC marking is conservative. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, pending certification.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Baton Rouge. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
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.
Likely candidates are refinery process units, chemical plant units, tank farms, dock and loading facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Baton Rouge.
Process units, pump rows, tank farms, loading racks and marine docks typically have Class I Division or Zone areas, often Group C or D. The refinery's classification drawings give specifics, so request them before specifying devices.
With a safety orientation, permit-to-work and gate checks, and often restrictions on personal electronics in process areas. Confirm the operator's requirements and approved-device list before you travel, and carry copies of device certificates.
ExxonMobil's refinery and chemical complex is in the city, with tank farms and dock and loading facilities on the Mississippi. Dow operates in neighbouring Iberville Parish, outside the city itself. Ask each operator which units and docks are classified and what equipment evidence it requires.
