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 Baton Rouge. In Louisiana refining, 'explosion-proof' is the traditional term for equipment suited to Class I locations, historically meaning heavy flameproof enclosures. Intrinsic safety is a distinct concept that suits a handheld. At process units, tank farms and docks the operator selects the protection concept area by area, so the everyday phrase should not be treated as a specification.

- 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.

Questions · Baton Rouge
Frequently asked questions
Can we buy an explosion proof 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 explosion proof mobile phone in Baton Rouge cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 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.
