Coastal climate
The setting is general hot, humid coastal conditions with salty air and monsoon rain, which favours sealed, corrosion-resistant devices.
Petronet LNG's Dahej terminal has a capacity of 17.5 million tonnes a year with eight LNG storage tanks and is being expanded to 22.5 million tonnes in two phases. It hosts Petronet LNG's terminal and petrochemical and liquid-handling operations, so gas, LNG and chemical handling create Zone 1 areas. An explosion proof 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.
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.

| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
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.
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.
The surrounding Bharuch district has a tropical savanna climate, with average maxima of about 40 degrees Celsius in April and May and around 800 millimetres of monsoon rain by September.
Port users include Petronet LNG, the Gujarat Chemical Port Terminal Company, ONGC OPAL, Birla Copper, Torrent Pharmaceuticals and Reliance Industries, each with its own jetty or facility.
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.
“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 Dahej, Gujarat. At an LNG terminal the phrase explosion-proof can mislead. Fixed pumps and electrical gear near regasification may use flameproof Ex d, while handheld devices on inspection rounds rely on intrinsic safety. Ethane and propane handling and the marine jetties add further reasons to check the protection concept, not the phrase.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Dahej, 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 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.
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.
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 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.
