The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Cilacap Refinery, Central Java. Across crude distillation, cracking and storage at Cilacap, explosion-proof means different things in different places. Flameproof Ex d enclosures protect fixed equipment, while a handheld carried through units and tank farms uses intrinsic safety. The refinery's classification drawings decide which concept is accepted.

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 explosion proof smartphone in Cilacap 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Cilacap Refinery, Central Java would use it?
Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Cilacap Refinery, Central Java?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Cilacap Refinery, Central Java.
Is Cilacap a good place to hold stock of replacement handsets for a long project?
It can be, because a refinery of this size typically runs continuous operations and periodic turnarounds that need many handheld devices. Plan spares, batteries and chargers in line with site rules, and check import and radio type-approval requirements first.
Who runs the Cilacap refinery and how do contractors get approved?
Refinery Unit IV is part of Pertamina's refining business under PT Kilang Pertamina Internasional. Suppliers and contractors typically register through Pertamina procurement and follow the unit's own safety induction and permit-to-work rules, so confirm the current route with the refinery.
Is the refinery's stated capacity relevant when choosing a handset for Cilacap?
Only indirectly. Published capacity figures vary slightly, but what matters for a device is the area classification and the operator's approval rules. Ask Pertamina for the current zone drawings and equipment procedure. Confirm with the site operator.
