ExxonMobil Beaumont
The refinery is reported at over 600,000 barrels a day after a 250,000 barrel a day crude unit expansion, with ethylene capacity of 816,000 tons a year on site.
Beaumont is part of the Golden Triangle with Port Arthur and Orange, where the 1901 Spindletop discovery began a large refining and petrochemical cluster. ExxonMobil's refinery and chemical complex is the city's largest private employer, with Zone 1 areas at process units and crackers. If you are specifying an intrinsically safe mobile phone for Beaumont, Texas, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Beaumont, Texas: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Beaumont Texas. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The refinery is reported at over 600,000 barrels a day after a 250,000 barrel a day crude unit expansion, with ethylene capacity of 816,000 tons a year on site.
The site is reported to use about 2,000 employees and 3,000 contractors daily, so contractor equipment is a significant need.
The Beaumont-Port Arthur metro area covers Hardin, Jefferson and Orange counties and had about 395,000 residents in 2023, giving local contractors a regional labour pool of several hundred thousand people.
The ExxonMobil Beaumont refinery and petrochemical complex is the city's largest private employer and occupies more than 2,000 acres across the city and its port.
Beaumont lies on the Neches River about 30 miles inland from the Gulf and 85 miles east of Houston, on flat ground only around 16 feet above sea level.
The Port of Beaumont, on the Neches River, is one of the largest seaports in the United States by tonnage, which keeps tanker and bulk traffic constant along the waterfront.
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 Beaumont, Texas. A large site with about 2,000 employees and 3,000 contractors reported daily has constant rounds and inspections across process units, crackers and marine terminals. A handheld designed for intrinsic safety lets crews record findings in the area without trips to a safe area for every note.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
Likely candidates are refinery process units, ethylene cracking units, lubricants plant, marine terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
US plants usually follow the National Electrical Code, which offers a Class and Division system and a Zone system. Which one applies is set by the site's area classification drawings, so ask the operator's safety or electrical team before choosing equipment.
The area has been hit by several hurricanes and tropical storms in recent years, so many operators keep spare equipment and plan storm shutdowns. It is sensible to hold spares and chargers off-site and agree replacement lead times in advance.
A name for the Beaumont, Port Arthur and Orange area, where the 1901 Spindletop discovery began a large refining and petrochemical cluster. The definition was not explicitly confirmed by every source checked. Confirm with the site operator which plants and areas a given task covers.
