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 Cilacap Refinery, Central Java. With a large site and many units, inspectors and operators cover long distances on rounds between process units, tank farms and marine loading. A handheld intended for intrinsic safety could carry checklists and photographs in one device, once certified and accepted by the operator.

Questions · Cilacap Refinery

Frequently asked questions

Can we buy an intrinsically safe smartphone in Cilacap Refinery 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 smartphone in Cilacap Refinery 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 Cilacap Refinery, Central Java would use it?

Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. 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 Cilacap Refinery, Central Java?

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 Cilacap Refinery, Central Java.

Is Cilacap a good place to hold stock of replacement handsets for a long project?

It can be, because a refinery of this size typically runs continuous operations and periodic turnarounds that need many handheld devices. Plan spares, batteries and chargers in line with site rules, and check import and radio type-approval requirements first.

Who runs the Cilacap refinery and how do contractors get approved?

Refinery Unit IV is part of Pertamina's refining business under PT Kilang Pertamina Internasional. Suppliers and contractors typically register through Pertamina procurement and follow the unit's own safety induction and permit-to-work rules, so confirm the current route with the refinery.

Is the refinery's stated capacity relevant when choosing a handset for Cilacap?

Only indirectly. Published capacity figures vary slightly, but what matters for a device is the area classification and the operator's approval rules. Ask Pertamina for the current zone drawings and equipment procedure. Confirm with the site operator.
