Crude receipt
Indian Oil states that crude arrives through three single point moorings about 25 km out to sea for very large crude carriers, with a captive South Oil Jetty in Paradip Port also used for crude imports and product exports.
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. Refining and polypropylene units create Zone 1 areas. This page explains what to look for in an intrinsically safe smartphone 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.
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.

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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Indian Oil states that crude arrives through three single point moorings about 25 km out to sea for very large crude carriers, with a captive South Oil Jetty in Paradip Port also used for crude imports and product exports.
The refinery sits on about 3,345 acres roughly 5 km from Paradip Port, and a polypropylene plant began operating in FY 2019-20.
A petrochemical complex of polypropylene, ethylene glycol and PX-PTA units is being added in stages, so construction and commissioning work continues on site.
Indian Oil's Paradip refinery was commissioned in 2016 at 15 million tonnes a year, covering about 3,345 acres about 5 kilometres south-west of Paradip Port.
Paradip sits at an average elevation of only about one metre above sea level, in Jagatsinghpur district of Odisha, about 90 kilometres from Cuttack.
Products include petrol, diesel, LPG, aviation turbine fuel, kerosene, sulphur and petroleum coke, with a polypropylene plant commissioned in 2019-20.
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 Paradip, Odisha. Rounds across process units, the polypropylene unit and product storage cover a large site, and marine checks add separate routines at the jetty. An intrinsically safe handheld supports logging at the asset. The IS-04Z1 is designed for this work, though certification is still in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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 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.
