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 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.

Questions · Baton Rouge
Frequently asked questions
Can we buy an Ex-proof smartphone 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 Ex-proof smartphone 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.
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 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.
