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 Pekanbaru and the Rokan block, Riau. The classified areas are gathering stations, wellheads and flowlines, oil treatment and storage, and steam generation and power facilities. PT Pertamina Hulu Rokan classifies them, not SAMS. Pekanbaru itself is a support city, so ask for the field's zone drawings.

Questions · Pekanbaru Oil Field
Frequently asked questions
Can we buy a hazardous area mobile phone in Pekanbaru Oil Field 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 mobile phone in Pekanbaru Oil Field 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.
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 Pekanbaru and the Rokan block, Riau would use it?
Likely candidates are gathering stations, wellheads and flowlines, oil treatment and storage, steam generation and power facilities. 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.
Why does steamflood production matter for equipment used at Duri?
Steamflood means hot steam lines and wells operate close to oil and gas handling, so surface temperatures can be higher than at conventional wells. Handheld devices should respect the site's temperature limits and classification, so ask the operator for its rules on portable electronics.
Which company operates the large oil fields around Pekanbaru today?
The Rokan block, including the Minas and Duri fields, has been run by Pertamina Hulu Rokan since August 2021. Contractors and suppliers typically register through Pertamina's vendor processes and follow the site's own induction and permit rules, so confirm current requirements.
Who approves suppliers for the Rokan block?
Suppliers are normally approved by the operator and its contractors, following Pertamina group processes since the 2021 operator change. Ask PT Pertamina Hulu Rokan about current registration requirements before offering any equipment. Confirm with the site operator.
