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 Surabaya and the Gresik industrial area. Across port fuel handling, fertiliser and chemical plants and cement works, explosion-proof covers different realities. Flameproof Ex d suits fixed motors; a handheld used on foot around chemical and fuel areas relies on intrinsic safety; cement dust areas need a dust approach.

Questions · Surabaya
Frequently asked questions
Can we buy an explosion proof smartphone in Surabaya 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 explosion proof smartphone in Surabaya 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 Surabaya and the Gresik industrial area would use it?
Likely candidates are port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate 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 move equipment between Surabaya and Madura or other East Java sites?
The Suramadu Bridge links Surabaya and Madura by road, and Tanjung Perak serves sea freight to eastern Indonesia. Allow time for customs clearance and for any site gate checks on electronic devices at plants and terminals.
Why is Surabaya a useful base for marine and shipyard work?
It has Indonesia's second-busiest seaport, a large shipyard and naval facilities, plus freight forwarders and customs brokers. Marine work typically involves tank entry and hot work, so confirm each yard's permit rules for portable electronic devices.
Can one handset serve both chemical plants and cement works around Surabaya?
Not necessarily. Chemical and fuel areas are gas hazards, while cement works are dust areas, and each needs a suitable marking. The IS-04Z1 target marking covers gas only. Check each area's classification with the operator.
