Inland site
Mathura is inland and is supplied with crude through the Salaya-Mathura pipeline, a 2,663 km line from the Gujarat coast, so there is no marine terminal.

More about Mathura, Uttar Pradesh that matters for portable equipment
Mathura, Uttar Pradesh: background
Mathura Refinery, Indian Oil's sixth refinery, was commissioned on 19 January 1982 after construction began in October 1972, so its older units are over 40 years old.
Mathura, Uttar Pradesh: who works there
The refinery processes low-sulphur Bombay High crude, imported Nigerian low-sulphur crude and high-sulphur Middle Eastern crude, so process conditions vary between crude types.
Mathura, Uttar Pradesh: geography and layout
Mathura city is 162 kilometres south-east of Delhi and about 15 kilometres from Vrindavan, on the Yamuna river.
Mathura, Uttar Pradesh: infrastructure
Crude arrives through the Salaya-Mathura pipeline, which also supplies the Panipat and Baroda refineries, so feedstock supply is a shared pipeline network.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Mathura, Uttar Pradesh. Rounds at product loading gantries, tank farms and pipeline pumping stations are routine and frequent, and truck movements add pressure to log quickly. An intrinsically safe handheld supports that work. The IS-04Z1 is designed for it, though certification is still in progress.

Questions · Mathura India
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Mathura India today?
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.
What does an intrinsically safe mobile phone in Mathura India cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which areas at Mathura, Uttar Pradesh would use it?
Likely candidates are refinery process units, crude and product tank farms, product loading gantries, pipeline pumping stations. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
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.
How hot does Mathura get for handsets?
Mathura has a hot semi-arid climate with very hot summers, so check the device's maximum operating and charging temperature on the datasheet and avoid leaving it in direct sun or vehicles.
What hazardous areas are at a refinery like Mathura?
Process units, tank farms, pump areas and loading gantries have classified areas for flammable gas and vapour. The operator defines these and specifies approved equipment, so request the area classification before entering.
How does hot, dusty summer weather affect handhelds at Mathura?
Heat can shorten battery life and dust can work into ports and seals. A sealed IP68 housing helps with dust. Keep devices out of direct sun between uses, and ask the operator about charging and storage arrangements for portable equipment during the hot months.
