Intrinsically Safe Mobile Phone in Timika Mining
Timika, capital of Mimika Regency in Central Papua, is the service base for the Grasberg copper and gold mine run by PT Freeport Indonesia. Concentrate goes by 166-kilometre slurry pipeline to the port at Amamapare, so hazardous areas include fuel, power, process plant and underground workings. This page explains what to look for in an intrinsically safe mobile phone for Timika and the Grasberg mining district, and where the IS-04Z1 stands against that list today.

Timika and the Grasberg mining district: industry on the ground
Flotation reagents separate a copper-gold concentrate, which is piped as slurry through three pipelines about 100 km to the port of Amamapare, where it is dewatered, dried and shipped to smelters.
Timika and the Grasberg mining district: infrastructure
The port facilities include a coal-fired power station that is to be replaced by 2027 with a 265 megawatt liquefied natural gas combined cycle plant, which will add an LNG supply chain to the site.
Timika and the Grasberg mining district: projects and investment
Grasberg held proven and probable reserves of 14.0 million tonnes of copper, 808 tonnes of gold and 3,773 tonnes of silver at the end of 2022, so mining is expected to continue for decades.
Timika and the Grasberg mining district: who works there
PT Freeport Indonesia runs Grasberg, with Indonesian state interests through MIND ID holding 51.23 percent and Freeport-McMoRan 48.77 percent, and mining rights were extended to 2041.
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 Timika and the Grasberg mining district. Inspection rounds link the concentrator, fuel storage and the port at Amamapare, with underground mines in three active areas. A handheld designed for intrinsic safety could hold checklists and photos, where permitted. Underground use needs the operator's specific approval.

Specifying an intrinsically safe mobile phone for Timika 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.

Questions · Timika Mining
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Timika Mining today?
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.
What does an intrinsically safe mobile phone in Timika Mining 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.
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 Timika and the Grasberg mining district would use it?
Likely candidates are concentrator and process plant, fuel storage and distribution, concentrate port and dewatering, underground mine 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.
Do underground mines at Grasberg use block caving and what does that mean for equipment?
Grasberg has block-cave and other underground operations with large ore flows and ventilation. Equipment in underground areas typically needs the approvals the operator specifies, and the mine controls access, so ask for its underground device and communications requirements.
Does the move to LNG power affect hazardous-area planning in Timika?
A planned 265 MW LNG-fired plant by 2027 would add natural gas storage and handling near the port, which sites usually classify as hazardous areas. Check with the operator for updated classification drawings if you will work near new power facilities.
Are underground areas at Grasberg covered by the same rules as surface plant?
Not necessarily. Underground mines have their own classification and approval rules set by the operator. A device accepted at the concentrator may not be accepted underground. Ask the operator's central safety team about each area.
