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 Dumai Refinery, Riau. Inspections between the Dumai and Sungai Pakning sites, and along marine jetties, create plenty of rounds. A handheld intended for intrinsic safety could hold checklists and photos for those trips. That use depends on certification and on Pertamina's acceptance.

Questions · Dumai Refinery
Frequently asked questions
Can we buy an intrinsically safe smartphone in Dumai 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 Dumai Refinery cost?
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.
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 Dumai Refinery, Riau would use it?
Likely candidates are refinery process units, crude and product tank farms, marine loading jetties. 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 Dumai Refinery, Riau?
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 Dumai Refinery, Riau.
Which Pertamina unit runs Dumai and how do contractors register?
Dumai is Pertamina's Refinery Unit II and its Sungai Pakning site is managed with it. Contractors and equipment suppliers usually register through Pertamina vendor processes and the unit's own safety induction, so confirm current requirements with the refinery.
Why are upgrade projects relevant for devices at Dumai?
National plans to upgrade the biggest refineries mean new process areas and construction activity beside operating units. Contractors in new areas typically follow the project's hazardous-area drawings, so check the classification for your specific work front rather than assuming existing plant limits.
Does Dumai have one set of rules or one per site?
The unit covers Dumai and Sungai Pakning, and each site has its own areas and drawings. Rules for devices are set by Pertamina, but practical details may differ. Ask the operator for requirements covering both sites. Confirm with the site operator.
