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.

Questions · Timika Mining
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Timika 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 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.
How do I become a SAMS distributor for Timika and the Grasberg mining district?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Timika and the Grasberg mining district.
What makes the Timika and Grasberg site different for handheld devices?
Altitude, heavy rain, long underground haulage and remote supply make it demanding. Underground mines can have gas or dust, and surface plants have flotation chemicals, so confirm area classification with the operator and plan for battery life and spares.
How is equipment normally delivered to Timika?
The operation uses its own port at Amamapare, an airstrip and long access roads built for the mine, and Timika is the regional town. Expect long lead times, customs clearance in Indonesia and site security and induction procedures before devices go underground.
How does altitude and rain at Grasberg affect a handset?
Grasberg sits at about 4,100 metres and the region is very wet, so temperature, condensation and battery behaviour matter. Check the rated operating range and sealing. IP68 is not explosion protection. Confirm site requirements with the operator.
