The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Jamnagar, Gujarat. Reliance describes extensive Zone 1 and Zone 2 areas across process units, petcoke gasification, the off-gas cracker and petrochemical units, tank farms and marine loading. The operator classifies these areas, not SAMS. PESO is the national regulator, and any device approval depends on Reliance's own site rules.

Questions · Jamnagar India
Frequently asked questions
Can we buy a hazardous area mobile phone in Jamnagar India today?
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.
What does a hazardous area mobile phone in Jamnagar India cost?
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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which areas at Jamnagar, Gujarat would use it?
Likely candidates are refinery process units, petcoke gasification, refinery off-gas cracker and petrochemical units, crude and product tank farms. 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.
Is Vadinar part of Jamnagar?
Vadinar is a separate coastal town in Devbhumi Dwarka district with its own refinery and crude oil terminals, about 47 kilometres from Jamnagar airport. Many contractors serve both sites, but access arrangements are separate.
What is the Jamnagar climate like for equipment?
It is hot semi-arid, with a very hot and humid season from March to May and an irregular monsoon. Cyclones occasionally occur, so look for sealed devices with a suitable temperature range.
Does one approval cover the whole Jamnagar complex?
Not automatically. The complex has many unit types, and each area has its own classification and permit regime. A device may be acceptable in one and not in another. Confirm with Reliance's site safety team which areas an approved handheld may be used in.
