Integrated port access takes vessels up to 350,000 DWT. Vadinar also has Deendayal Port Authority and Indian Oil single buoy moorings, with port expansion under way.
Vadinar, in Devbhoomi Dwarka district on the Gulf of Kutch, has a 20 million tonne a year refinery operated by Nayara Energy, formerly Essar Oil, and offshore crude moorings. The Bharat Oman Refineries crude oil terminal is also at Vadinar and supplies its refinery at Bina in Madhya Pradesh. This page explains what to look for in an explosion proof mobile phone for Vadinar, Gujarat, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Vadinar, Gujarat: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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 | Vadinar, Gujarat: Refinery process units, Delayed coker, Single buoy mooring and tankage | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Vadinar 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.
Integrated port access takes vessels up to 350,000 DWT. Vadinar also has Deendayal Port Authority and Indian Oil single buoy moorings, with port expansion under way.
The site lies a few kilometres from the Jamnagar complex, so contractors often serve both. Conditions are generally hot and humid with monsoon rain.
The nearest airport is at Jamnagar, 47 kilometres away, and Vadinar is a small coastal town in Devbhumi Dwarka district.
The Jamnagar area has a hot semi-arid climate with extremely hot and humid conditions from March to May and an erratic monsoon of about 500 millimetres.
The Marine National Park at Narara Island lies about 7 kilometres from the town, and a salt production unit operates locally.
Indian Oil's crude oil terminal at Vadinar is secured by the Central Industrial Security Force, as is Kandla port, so site security and ID checks are strict.
“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 Vadinar, Gujarat. At a refinery with a delayed coker, tankage and offshore moorings, explosion-proof is a loose phrase. Fixed plant may be flameproof Ex d, while a handheld on inspection rounds relies on intrinsic safety. Mooring and port areas have separate marine rules.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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, delayed coker, single buoy mooring and tankage, product dispatch by sea, rail and road. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Crude oil terminals, single-buoy moorings, pipelines and the refinery have classified areas due to flammable vapours. Operators define them, so request area classification and approved equipment lists before visiting.
The nearest airport is at Jamnagar, 47 kilometres away, with the final leg by road in a small coastal town. Confirm gate procedures, security passes and visit timings with each operator in advance.
Moorings and port areas have separate marine procedures, weather limits and permits. Salt spray and rain also stress devices. Confirm with the refinery and port authorities which devices are permitted at the moorings and how portable equipment is controlled during marine operations.
