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 Mathura, Uttar Pradesh. Mathura's hazardous areas include refinery process units, crude and product tank farms, product loading gantries and pipeline pumping stations. Indian Oil, the operator, classifies its own areas. PESO is the national regulator, and SAMS has no role in classifying or approving any area.

Questions · Mathura India
Frequently asked questions
Can we buy a hazardous area smartphone in Mathura India today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does a hazardous area smartphone in Mathura 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 Mathura, Uttar Pradesh would use it?
Likely candidates are refinery process units, crude and product tank farms, product loading gantries, pipeline pumping stations. 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 hot does Mathura get for handsets?
Mathura has a hot semi-arid climate with very hot summers, so check the device's maximum operating and charging temperature on the datasheet and avoid leaving it in direct sun or vehicles.
What hazardous areas are at a refinery like Mathura?
Process units, tank farms, pump areas and loading gantries have classified areas for flammable gas and vapour. The operator defines these and specifies approved equipment, so request the area classification before entering.
How does hot, dusty summer weather affect handhelds at Mathura?
Heat can shorten battery life and dust can work into ports and seals. A sealed IP68 housing helps with dust. Keep devices out of direct sun between uses, and ask the operator about charging and storage arrangements for portable equipment during the hot months.
