Site
The refinery sits on about 3,345 acres roughly 5 km from Paradip Port, and a polypropylene plant began operating in FY 2019-20.
Paradip on the Odisha coast hosts Indian Oil's 15 million tonne a year refinery, inaugurated on 7 February 2016, which processes heavy crude received through offshore single point moorings. Other companies in Paradip include IFFCO, Paradeep Phosphates, Bharat Petroleum, Hindustan Petroleum and Goa Carbon, so the town hosts fertiliser and fuel operators. This page explains what to look for in an explosion proof mobile phone for Paradip, Odisha, 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 Paradip, Odisha: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Paradip 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 refinery sits on about 3,345 acres roughly 5 km from Paradip Port, and a polypropylene plant began operating in FY 2019-20.
The Odisha coast is generally hot and humid with monsoon rain and cyclone exposure, so sealed devices suit outdoor work.
Products include petrol, diesel, LPG, aviation turbine fuel, kerosene, sulphur and petroleum coke, with a polypropylene plant commissioned in 2019-20.
The refinery says it discharges zero effluent and that its stack emissions are uplinked to the server of the Central Pollution Control Board.
It is the first Indian Oil refinery to process 15 million tonnes a year through a single atmospheric column and can process heavy crude oil.
The nearest commercial airport is Biju Patnaik International Airport, and Paradip is on National Highway 53.
“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 Paradip, Odisha. At a refinery processing heavy crude, with a polypropylene unit and offshore moorings, explosion-proof is shorthand. Fixed plant may be flameproof Ex d, while handhelds on rounds rely on intrinsic safety. Offshore mooring and jetty areas have their own conditions and permits.
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.
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 refinery process units, crude receipt via single point moorings, polypropylene unit, product storage and loading. 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.
Yes, Paradip is only about one metre above sea level on the Odisha coast, so humidity, salt air and storm events matter. Choose sealed, corrosion-resistant devices and confirm the ratings on the datasheet.
The refinery has a large atmospheric column, cracker and coker areas, tank farms and jetty facilities, with classified zones set by the operator. Request the area classification before taking portable devices.
Only if the operator and marine authorities allow it and the device suits the area classification. Moorings are about 25 km offshore and have separate marine procedures. Confirm with the operator which devices are permitted there and under what permit.
