Coastal climate
The Odisha coast is generally hot and humid with monsoon rain and cyclone exposure, so sealed devices suit outdoor work.

The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Paradip, Odisha. A marking check at Paradip should compare the device with process units, polypropylene, product loading and crude receipt areas. Heavy crude units and propylene can sit in different gas groups. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, and the operator's classification decides suitability.

Questions · Paradip India
Frequently asked questions
Can we buy an Ex-proof smartphone in Paradip 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 Ex-proof smartphone in Paradip 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 Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Paradip, Odisha would use it?
Likely candidates are refinery process units, crude receipt via single point moorings, polypropylene unit, product storage and loading. 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 Paradip a low-lying coastal site?
Yes, Paradip is only about one metre above sea level on the Odisha coast, so humidity, salt air and storm events matter. Choose sealed, corrosion-resistant devices and confirm the ratings on the datasheet.
What hazardous areas are at Paradip refinery?
The refinery has a large atmospheric column, cracker and coker areas, tank farms and jetty facilities, with classified zones set by the operator. Request the area classification before taking portable devices.
Can a handheld be used at the offshore moorings serving Paradip?
Only if the operator and marine authorities allow it and the device suits the area classification. Moorings are about 25 km offshore and have separate marine procedures. Confirm with the operator which devices are permitted there and under what permit.
