Dense urban setting
The refineries sit in the Mahul-Chembur area within the metropolitan region, which Wikipedia notes is surrounded by a number of chemical plants, so site access and security controls are normally strict.

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 Mumbai, Maharashtra. Rounds across process units, storage terminals and marine oil handling in a congested urban area mean frequent walking between tightly packed assets. An intrinsically safe handheld supports logging in place. The IS-04Z1 is designed for this kind of work, with certification still in progress.

Questions · Mumbai India
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Mumbai 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 intrinsically safe mobile phone in Mumbai India cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 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.
