Coastal climate
The setting is general hot, humid coastal conditions with salty air and monsoon rain, which favours sealed, corrosion-resistant devices.
The nearest airports are at Ahmedabad, Surat and Vadodara, and Bharuch, about 45 kilometres away, is being connected to Dahej by a broad-gauge rail siding. It hosts Petronet LNG's terminal and petrochemical and liquid-handling operations, so gas, LNG and chemical handling create Zone 1 areas. A hazardous area smartphone distributor in Dahej, Gujarat would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Dahej, 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Dahej India. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The setting is general hot, humid coastal conditions with salty air and monsoon rain, which favours sealed, corrosion-resistant devices.
Petronet LNG reported the Dahej terminal expanded from 17.5 to 22.5 million tonnes a year, with the additional capacity commissioned by 31 March 2026. A third jetty for LNG, ethane and propane is being built.
The hinterland is being developed as a special economic zone of 30,000 hectares, with the four-lane highway being widened to six lanes and the rail line upgraded to broad gauge sidings.
The chemical port terminal can handle liquid cargo at up to 25,000 tonnes a day, and a bulk facility unloads up to 30,000 tonnes a day, so liquid and dust hazards both occur on the waterfront.
Tides at Dahej are large: high water can rise 10 to 11 metres, and vessels anchor about 5.5 kilometres from the old port, so marine work depends on tide tables.
Dahej has two LNG jetties, the first for Q-Flex vessels and the second for Q-Max carriers, and had handled 3,538 cargoes by 30 September 2024.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Dahej, Gujarat. Hazardous areas at Dahej include LNG storage and regasification, ethane and propane handling, marine jetties, petrochemical plants and liquid chemical tank terminals. Operators such as Petronet LNG, OPaL and GCPTCL are responsible for classifying their areas. PESO is the national regulator, and SAMS makes no classification decisions.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Dahej, Gujarat yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service 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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are lng storage and regasification, ethane and propane handling, marine jetties, petrochemical plants. 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 Dahej, Gujarat.
High water can rise 10 to 11 metres, which affects vessel movements, jetty operations and marine support work. Schedules usually follow tide tables, so build flexibility into plans for jetty visits.
LNG sites typically classify areas around storage tanks, vaporisation units, jetty loading arms and truck loading bays, because vapour can form a flammable mixture with air. The operator defines the zones, so request the drawings and accepted approvals before entering.
Check ingress rating, corrosion resistance of connectors and seals, and how the device is stored between shifts. Heavy rain, salty air and heat all matter. IP68 helps with water, but explosion protection comes only from the marking. Ask the operator about its portable equipment rules in wet weather.
