Intrinsically Safe Mobile Phone in Indonesia Mining
Indonesian mining includes coal in Kalimantan, nickel in Sulawesi and the Grasberg copper-gold complex in Papua. Fuel storage, coal handling, process plants and smelters create hazardous areas, with dust areas at coal preparation and underground work at Grasberg. If you are specifying an intrinsically safe mobile phone for Indonesian mining regions, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Indonesian mining regions: projects and investment
PT Borneo Alumina Indonesia finished an alumina refinery in West Kalimantan with a capacity of 1 million tonnes a year, starting operations in December 2024, and Freeport built a 0.6 million tonne copper smelter at Manyar in East Java.
Indonesian mining regions: infrastructure
Nickel output reached about 2.2 million tonnes in 2023 and relies heavily on coal-fired power, accounting for around 22 percent of national energy and industrial emissions, so captive coal power plants sit beside many smelters.
Indonesian mining regions: infrastructure
The Indonesia Morowali Industrial Park in Central Sulawesi, the country's largest nickel processing site, covers 2,000 hectares and is served by its own seaport, an airport and a 2 GW coal power plant.
Indonesian mining regions: industry on the ground
In 2024 Indonesia was estimated to be the world's leading producer of mined nickel at 62 percent of global output, and second for tin at 19 percent and cobalt at 12 percent.
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 Indonesian mining regions. Mine inspections, fuel storage checks and plant rounds are spread over large, remote sites. A handheld designed for intrinsically safe use could keep checklists and photos on one device, but only where its gas marking suits the area. Underground and dust areas need separate assessment.

Specifying an intrinsically safe mobile phone for Indonesia Mining
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Indonesia Mining
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Indonesia Mining 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 Indonesia Mining cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined 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 Indonesian mining regions would use it?
Likely candidates are coal handling and preparation plants (dust, zone 21), fuel and lubricant storage, underground mine areas, smelter and process plant areas. 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.
Which parts of a mining operation in Indonesia need hazardous-area equipment?
Typical examples are underground methane or coal-dust zones, fuel storage and workshops, explosives magazines, smelter and processing areas with gases or dust, and captive power plants. Each operator classifies its own site, so confirm the zones with the mine's safety department.
Are nickel smelter sites different from coal mines for phone and radio use?
Yes. Smelters and acid-leach plants emphasise process gases, chemicals and high temperatures, while coal mines emphasise methane and combustible dust. The device choice and the area type differ, so ask each site for its classification and permit rules.
How should remote mine sites affect a buying decision?
Remote operations rely on long supply chains, so a failed device may take time to replace. Plan spares, local service access and offline-capable apps. Check heat, wet and altitude conditions at each site. Confirm site rules with the operator.
