Field notes · Baton Rouge
More about Baton Rouge that matters for portable equipment
Baton Rouge: geography and layout
Baton Rouge is the Louisiana state capital with more than 800,000 residents and is a significant port and a major industrial and petrochemical centre on the Mississippi River.
Baton Rouge: rules and approvals
The refinery operates under a Title V major air permit and reports greenhouse gas emissions to the EPA each year, so environmental compliance is part of site management.
Baton Rouge: industry on the ground
The refinery has a capacity of 540,000 barrels per day as of 2020, and the main plant sits on the east bank of the Mississippi River.
Baton Rouge: infrastructure
Eight interconnected sites operate round the clock and the complex produces more than 2.9 billion pounds of products annually, with the operator being the state's second-largest employer.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Baton Rouge. A US reviewer in Baton Rouge would more often ask for NEC-based Class and Division evidence, but ExxonMobil and Dow engage international EPCs who may carry ATEX or IECEx documents. A dual route is designed to help those visitors. Both certifications are in progress for SAMS, and none has been issued.

Questions · Baton Rouge
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Baton Rouge today?
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.
What does an ATEX and IECEx mobile phone in Baton Rouge cost?
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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Baton Rouge would use it?
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.
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.
US Division or IEC Zone marking: which does Baton Rouge accept?
US refineries traditionally use NEC Class and Division, and many now accept IEC Zone-marked equipment. Confirm which scheme and gas group the facility's classification uses and what certification mark it accepts.
Does hurricane season matter for scheduling work in Baton Rouge?
The Gulf Coast has a hurricane season, which can alter work schedules and site access. Confirm schedule risk and weather policy with the operator and contractor.
Does Baton Rouge use Class and Division or Zones?
US plants have traditionally used Class and Division, and Zone-based classification is also used. Which applies depends on the operator's engineering standards for each area. ExxonMobil's engineering and safety teams approve equipment, so confirm requirements with the site operator before specifying.
