LNG terminal
Shell Energy India operates the Hazira LNG terminal. The environmental clearance granted on 2 September 2025 covers expansion from 6.28 to 26.2 million tonnes a year, so this is an approved project rather than existing capacity.
Hazira is an industrial and port suburb of Surat in Gujarat, on the Tapti River about 8 km from the Arabian Sea. Its LNG terminal, gas and petrochemical plants and heavy engineering works create Zone 1 and Zone 21 areas. If you are specifying an intrinsically safe smartphone for Hazira, Surat, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Hazira, Surat: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |

| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Hazira 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.
Shell Energy India operates the Hazira LNG terminal. The environmental clearance granted on 2 September 2025 covers expansion from 6.28 to 26.2 million tonnes a year, so this is an approved project rather than existing capacity.
Wikipedia lists Reliance, ONGC, Shell, NTPC, L&T and KRIBHCO among the major Hazira operators, with L&T's shipyard and heavy engineering complex alongside.
It has two full-containment cryogenic tanks of 160,000 cubic metres each, 80 metres across and 40 metres high, holding LNG at minus 165 degrees Celsius.
A 1.3 kilometre jetty can accept LNG carriers of up to 145,000 cubic metres, and from July 2010 the terminal has been open for use by other companies.
Hazira is a suburb and port of Surat on the Tapti River, about 8 kilometres from the Arabian Sea and 22 kilometres from Surat city, a 30 to 35 minute drive.
The Hazira LNG terminal in Surat district was designed for 5 million tonnes a year of regasification, expandable to 10 million tonnes depending on demand.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Hazira, Surat. Rounds across LNG regasification, gas processing, petrochemical plants and marine terminals involve walking long distances between units. A handheld that is intrinsically safe by design lets an operator log and photograph in place. The IS-04Z1 is designed for such rounds, subject to certification still in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are lng regasification, gas processing, petrochemical plants, marine terminals. 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.
Hazira is 22 kilometres from Surat and the drive takes about 30 to 35 minutes. Most visitors fly into Surat, and heavy plant traffic and monsoon rain can slow the road.
Hazira combines an LNG terminal, gas and power plants, a manufacturing division and a shipyard, so it has gas-hazard zones, hot-work areas and mixed-use industrial zones. Always get the area classification and equipment rules from the specific operator.
The terminal operator does, through its permit and area classification system, with PESO as national regulator. Rules usually cover approved equipment, permits and charging. Ask the operator's safety team what evidence they need from a supplier before a new handheld may enter.
