Capacity figures
Wikipedia quotes 1.24 million barrels a day, while Reliance's current site quotes 1.4 million; the operator's figure is used here.
Jamnagar is known as the Brass City, with over 5,000 large and 10,000 small brass workshops, so local engineering and fabrication skills are widely available. Process units, tank farms and marine facilities create extensive Zone 1 and Zone 2 areas. An explosion proof mobile phone distributor in Jamnagar, Gujarat would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Jamnagar, Gujarat 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Jamnagar, Gujarat: Refinery process units, Petcoke gasification, Refinery off-gas cracker and petrochemical units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Jamnagar India. 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.
Wikipedia quotes 1.24 million barrels a day, while Reliance's current site quotes 1.4 million; the operator's figure is used here.
Wikipedia gives the refinery's commissioning as July 1999 and the site as over 7,500 acres, with utilities, port infrastructure and worker housing. Reliance's own site lists a refinery off-gas cracker and the world's largest petcoke gasifier.
Tropical cyclones sometimes affect the area during the wet season, so operators plan for storm events.
The metropolitan area had about 877,000 residents in 2025, most speak Gujarati, and the literacy rate is about 82 percent.
The complex covers over 7,500 acres and includes utilities, port facilities and a 415-acre township for about 2,500 employees, according to a 2013 description.
The refinery was commissioned within 36 months, which means much of its equipment dates from around the turn of the century.
“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 Jamnagar, Gujarat. At a refinery with petcoke gasification, an off-gas cracker and large tank farms, explosion-proof covers many concepts. Fixed motors and junction boxes may be flameproof Ex d, while a handheld carried through units and tank farms relies on intrinsic safety. The area type decides which concept is acceptable.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Jamnagar, Gujarat. 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 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.
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.
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.
Likely candidates are refinery process units, petcoke gasification, refinery off-gas cracker and petrochemical units, crude and product tank farms. 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 Jamnagar, Gujarat.
The refinery complex handles over a million barrels a day plus petrochemical units and port facilities, so classified areas are extensive. The operator sets the zones and equipment rules, so confirm them before entering.
The area has a large industrial and fabrication base, including thousands of brass workshops, and a workforce that mostly speaks Gujarati. Operators still require site induction, so plan time for approvals.
Large sites mean long walks and long shifts, so battery life, charging points and a robust housing matter. Charging must happen in safe areas, not in classified ones. Ask the operator what charging and spare-device arrangements are permitted before planning a fleet.
