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 Balikpapan, East Kalimantan. With a new residual cracking unit and a naphtha unit being added, there will be commissioning walk-downs and startups across the refinery. A handheld intended for intrinsic safety could carry checklists and photos through those rounds. That use depends on certification and on Pertamina's acceptance.

Questions · Balikpapan
Frequently asked questions
Can we buy an intrinsically safe smartphone in Balikpapan 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 smartphone in Balikpapan 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 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 Balikpapan, East Kalimantan would use it?
Likely candidates are refinery process units, residual fluid catalytic cracking unit, crude and product storage, marine crude mooring and tanks. 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.
Does Balikpapan only matter for refining, or are other hazardous industries nearby?
Oil and gas dominate the local story, with the refinery, fuel terminals and port tank storage. East Kalimantan also has coal and LNG activity regionally, but confirm with each operator which classified-area rules and device permits apply to its own facility.
Is Balikpapan easy to reach for equipment delivery?
Reasonably. The city has an international-class airport at Sepinggan and the Semayang seaport, and it is the main commercial centre of Kalimantan. Allow time for customs clearance and for any site gate checks on electronic devices entering the refinery.
How should a buyer think about heat and humidity at Balikpapan?
Equatorial heat and constant humidity affect battery life, seals and charging habits. Check the rated operating temperature range and keep charging in a safe area, away from classified zones. IP68 is useful against rain, but it is not explosion protection.
