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 Dumai Refinery, Riau. Across Dumai's process units, tank farms and jetties, explosion-proof is everyday shorthand. Flameproof Ex d serves fixed equipment, whereas a handheld carried between units relies on intrinsic safety. Products such as LPG and jet fuel are classified by the operator, who decides the accepted concept.

Questions · Dumai Refinery
Frequently asked questions
Can we buy an explosion proof 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 explosion proof 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.
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 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.
