The term · explosion proof
What “explosion proof” means for a smartphone
“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 Jamnagar, Gujarat. At a refinery with petcoke gasification, an off-gas cracker and large tank farms, explosion-proof covers many concepts. Fixed motors and junction boxes may be flameproof Ex d, while a handheld carried through units and tank farms relies on intrinsic safety. The area type decides which concept is acceptable.

Questions · Jamnagar India
Frequently asked questions
Can we buy an explosion proof 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 an explosion proof mobile phone in Jamnagar India cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
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.
