Hazardous Area Smartphone in Dumai Refinery
Dumai, on the Riau coast of Sumatra, hosts Pertamina's Refinery Unit II, with Dumai and Sungai Pakning sites and a combined capacity reported at 170,000 barrels per day. All six of Indonesia's oil refineries are run by Pertamina, and together they supplied only about half of national fuel demand, which is why upgrade programmes cover the largest units including Dumai. This page explains what to look for in a hazardous area smartphone for Dumai Refinery, Riau, and where the IS-04Z1 stands against that list today.

The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Dumai Refinery, Riau. Refinery process units, crude and product tank farms and marine loading jetties are the classified areas here, across both Dumai and Sungai Pakning. Pertamina classifies them, not SAMS. A buyer should ask for the zone drawings of each site separately.

Questions · Dumai Refinery
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area smartphone in Dumai Refinery 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
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.
Does green coke at Dumai create a dust hazard for electronics?
Green coke is a petroleum-coke product, and fine carbon dust can be combustible and conductive. Where it is handled, sites may classify combustible-dust zones, so ask the operator whether your handset needs a dust-rated device and how often it must be cleaned.
Is Dumai reachable for equipment shipments?
Dumai is a coastal port city in Riau Province, so sea freight is practical, and many visitors fly to Pekanbaru and continue by road. Plan for customs clearance in Indonesia and a site gate check, and confirm lead times with your freight agent.
Is Dumai's humidity a problem for a handset?
Equatorial heat and rain through the year affect battery performance and seals, so check the rated operating range and charging arrangements. Charge only in safe areas. Rain protection does not equal explosion protection. Confirm the permitted device list with the operator.
