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 Mumbai, Maharashtra. Mumbai's hazardous areas include refinery process units, petroleum storage terminals, marine oil handling and chemical plants. BPCL and HPCL classify their own areas, and neighbouring chemical plants do the same. PESO is the national regulator, and SAMS has no role in classifying or approving any area.

Questions · Mumbai India
Frequently asked questions
Can we buy a hazardous area mobile phone in Mumbai 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 Mumbai 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 Mumbai, Maharashtra would use it?
Likely candidates are refinery process units, petroleum storage terminals, marine oil handling, chemical plants. 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 do I ship equipment to Mumbai?
Jawaharlal Nehru Port is the main container port for the region, with 30 container freight stations and links to inland depots. Use an experienced freight forwarder and confirm customs documents in advance.
How does the Mumbai monsoon affect equipment and logistics?
Rain is heavy from June to September, peaking in July, and monsoon floods can disrupt roads and ports. Plan deliveries and site visits outside the peak monsoon where possible, and transport devices in waterproof cases.
What should be planned for the monsoon at Mumbai sites?
Intense rain from June to September makes water and corrosion protection important for outdoor work. A sealed IP68 design helps, but users should still check seals and dry the device. Ask the operator how outdoor handheld use is managed during heavy rain.
