Reduced operation
Declining feed gas has cut output since 2001. Reporting in 2025 put only two trains in operation, with reactivation of Train F targeted for October 2028 as new gas arrives.
Bontang hosts the Badak LNG plant, owned by Pertamina and run by PT Badak NGL. Bontang has a tropical rainforest climate with warm, stable temperatures and abundant rain, a drier period from about May to September and a wetter one from November to May. This page explains what to look for in an explosion proof smartphone for Bontang LNG (Badak LNG), East Kalimantan, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Bontang LNG (Badak LNG), East Kalimantan: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Bontang LNG (Badak LNG), East Kalimantan: LNG liquefaction trains, LNG and LPG storage tanks, Gas pipelines | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Bontang LNG. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Declining feed gas has cut output since 2001. Reporting in 2025 put only two trains in operation, with reactivation of Train F targeted for October 2028 as new gas arrives.
Hot, humid equatorial conditions on the East Kalimantan coast.
Bontang Industrial Technology College (STTIB) is the city's best known higher education institution, supplying local technicians for the gas, fertiliser and coal industries.
PT Pupuk Kaltim, set up in 1977, turns local natural gas into ammonia and urea with four ammonia and five urea units, about 1.85 million tonnes of ammonia and 2.98 million tonnes of urea a year.
The city's only airport is the private PT Badak Bontang Airport owned by Badak NGL, and its principal seaport is Loktuan Port, which was being expanded to relieve congestion at Balikpapan.
PT Badak LNG was established on 26 November 1974 as a joint venture with Pertamina, Total, Vico and Jilco, and it currently produces around 22 million tonnes of LNG a year, mostly exported to Japan.
“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 Bontang LNG (Badak LNG), East Kalimantan. Around liquefaction trains and storage tanks, explosion-proof is a casual term. Flameproof Ex d enclosures suit fixed equipment, while a handheld carried along pipework or tanks relies on intrinsic safety. Methane and LPG areas are classified by the operator, which determines the accepted concept for each place.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
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.
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.
Likely candidates are lng liquefaction trains, lng and lpg storage tanks, gas pipelines, loading jetties. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
The main ones are LNG and natural-gas processing areas, ammonia and urea plants, and coal handling with combustible dust. Each operator classifies its own plant, so ask Badak LNG, Pupuk Kaltim or the mine for its zone drawings before bringing handheld devices on site.
Yes. A tropical rainforest climate with frequent heavy rain, warm stable temperatures and sea air tends to stress seals, connectors and chargers. Typically users specify good ingress protection and keep spare batteries and cleaning routines, subject to the plant's rules.
Jetties and coastal areas expose devices to heat, humidity and salt air. Check the rated temperature range, seals and charging contacts. Charge only in safe areas. Water and dust protection does not replace explosion protection. Confirm site practice with the operator.
