India: geography and layout
The largest crude reserves are in the Western Offshore region at 37 per cent and Assam at 27 per cent, so both offshore platforms and remote north-eastern fields matter.

Intrinsically Safe Mobile Phone in India
The IS-04Z1 is designed for people who work inside classified areas at Indian refineries, gas plants, LNG jetties and API blocks: field operators, inspection engineers, shift in-charges, and the HSE and materials teams whose sign-off a device has to survive. If you are specifying an intrinsically safe mobile phone for India, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for India: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about India that matters for portable equipment
India: rules and approvals
Imports are applied for by an Indian service provider or distributor, and there is no separate PESO mark; the Ex marking and the approval letter show compliance.
India: industry on the ground
India imports 82 per cent of its oil needs, so import terminals, tank farms and coastal refineries are central to supply.
India: background
India's first oil deposits were found near Digboi in Assam in 1889, and its gas industry began in the 1960s with discoveries in Assam and the Mumbai High field.
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 India. Field operators, inspection engineers and shift in-charges at Indian refineries and gas plants make rounds that cross zone boundaries many times. An intrinsically safe handheld lets them record readings and photograph issues at the point of work, rather than walking to a safe area. That is the design intent, pending approval.

Specifying an intrinsically safe mobile phone for India
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · India
Frequently asked questions
Can we buy an intrinsically safe mobile phone in 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 intrinsically safe mobile phone in 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.
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 sites in India does this cover?
The market guide for India covers Jamnagar, Gujarat, Dahej and the Gujarat PCPIR, Hazira and Surat, Vadodara, Koyali, Ankleshwar, among others. Site-level pages are linked below.
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 PESO approval needed for Ex phones in India?
PESO approval is required for Ex electrical apparatus at petroleum, gas cylinder and pressure vessel premises, and imports are applied for through an Indian service provider or distributor. Whether it applies to a given site depends on the licensing category, so ask the site's safety team and a PESO consultant.
Where does hazardous-area work concentrate in India?
Typically the large coastal refineries such as Jamnagar, offshore platforms in the Western Offshore region, petrochemical and fertiliser complexes, and gas fields in Assam and Gujarat. Each operator issues its own area classification, so request the drawing, gas group and temperature class first.
Which Indian approvals apply to this handset?
The market guide lists PESO, BIS and WPC approvals as in progress, alongside IECEx. None has been granted yet. Which are needed for a given site depends on the operator and the regulator, so ask the site operator and check the current status before ordering.
