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 Hazira, Surat. Hazardous areas at Hazira include LNG regasification, gas processing, petrochemical plants and marine terminals. Each operator, such as Shell, Reliance, ONGC or NTPC on their own sites, classifies its own areas. PESO is the national regulator, and SAMS does not classify any site or approve any area.

Questions · Hazira India
Frequently asked questions
Can we buy a hazardous area mobile phone in Hazira 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 Hazira 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 Hazira, Surat would use it?
Likely candidates are lng regasification, gas processing, petrochemical plants, marine terminals. 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 long is the transfer from Surat to Hazira?
Hazira is 22 kilometres from Surat and the drive takes about 30 to 35 minutes. Most visitors fly into Surat, and heavy plant traffic and monsoon rain can slow the road.
What mix of hazardous areas does Hazira have?
Hazira combines an LNG terminal, gas and power plants, a manufacturing division and a shipyard, so it has gas-hazard zones, hot-work areas and mixed-use industrial zones. Always get the area classification and equipment rules from the specific operator.
Who sets the rules for carrying a handheld into an LNG terminal at Hazira?
The terminal operator does, through its permit and area classification system, with PESO as national regulator. Rules usually cover approved equipment, permits and charging. Ask the operator's safety team what evidence they need from a supplier before a new handheld may enter.
