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 Dumai Refinery, Riau. Inspections between the Dumai and Sungai Pakning sites, and along marine jetties, create plenty of rounds. A handheld intended for intrinsic safety could hold checklists and photos for those trips. That use depends on certification and on Pertamina's acceptance.

Questions · Dumai Refinery
Frequently asked questions
Can we buy an intrinsically safe smartphone in Dumai Refinery 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 an intrinsically safe smartphone in Dumai Refinery 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 Dumai Refinery, Riau would use it?
Likely candidates are refinery process units, crude and product tank farms, marine loading jetties. 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 green coke at Dumai create a dust hazard for electronics?
Green coke is a petroleum-coke product, and fine carbon dust can be combustible and conductive. Where it is handled, sites may classify combustible-dust zones, so ask the operator whether your handset needs a dust-rated device and how often it must be cleaned.
Is Dumai reachable for equipment shipments?
Dumai is a coastal port city in Riau Province, so sea freight is practical, and many visitors fly to Pekanbaru and continue by road. Plan for customs clearance in Indonesia and a site gate check, and confirm lead times with your freight agent.
Is Dumai's humidity a problem for a handset?
Equatorial heat and rain through the year affect battery performance and seals, so check the rated operating range and charging arrangements. Charge only in safe areas. Rain protection does not equal explosion protection. Confirm the permitted device list with the operator.
