Hazardous Area Smartphone in Surabaya
Surabaya is the capital of East Java and home to Tanjung Perak, Indonesia's second-largest port. The city hosts a large shipyard and several naval schools, and in the Dutch colonial era hosted the most extensive naval base in the colony, so marine and ship-repair work is a core local activity. This page explains what to look for in a hazardous area smartphone for Surabaya and the Gresik industrial area, and where the IS-04Z1 stands against that list today.

The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Surabaya and the Gresik industrial area. Classified areas span port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas and chemical plants in the industrial estate. Each plant or terminal operator classifies its own areas, not SAMS. Ask each for its drawings.

Questions · Surabaya
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area smartphone 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
