Intrinsically Safe Mobile Phone in Surabaya
Surabaya is the capital of East Java and home to Tanjung Perak, Indonesia's second-largest port. The Surabaya Industrial Estate Rungkut and neighbouring Gresik, with a fertiliser plant and cement works, hold the chemical, fuel and process areas where Zone 1 and Zone 21 equipment applies. This page explains what to look for in an intrinsically safe mobile phone for Surabaya and the Gresik industrial area, and where the IS-04Z1 stands against that list today.

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 Surabaya and the Gresik industrial area. Operators at chemical plants and port fuel handling walk between tanks, process areas and quays on rounds. A handheld designed for intrinsic safety could hold checklists and photos in one device where its gas marking fits. Dust areas at cement works need separate assessment.

Questions · Surabaya
Frequently asked questions
Can we buy an intrinsically safe mobile phone 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 intrinsically safe mobile phone in Surabaya cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.
