Petronas: background
The first oil well in Malaysia was drilled at Miri in Sarawak in 1910, known as the Grand Old Lady, which shows a long industrial history in north Borneo and ageing facilities in places.
PETRONAS is Malaysia's state-owned oil and gas company, integrated across exploration, production, refining, gas, LNG and petrochemicals. Its Malaysian sites include the Kertih petrochemical complex, Bintulu LNG, Melaka refining and the Pengerang integrated complex. This page explains what to look for in an intrinsically safe smartphone for Petronas, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Petronas: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Petronas: Refinery process units, Petrochemical complexes, Gas processing plants | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Malaysia. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Where it operates and the kinds of classified area a handset would meet there.
Suppliers apply for a PETRONAS licence or registration through the PETRONAS Licensing Management System (PLMS), then trade through its procurement platforms such as the Unified Procurement Platform and B2B Marketplace. A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
The first oil well in Malaysia was drilled at Miri in Sarawak in 1910, known as the Grand Old Lady, which shows a long industrial history in north Borneo and ageing facilities in places.
Petronas made its first crude shipment, 358,000 barrels to Japan, on 1 September 1975, and its lubricants subsidiary now operates in over 100 markets, indicating strong export and marine logistics.
Petronas Carigali, formed in 1978, is the principal exploration and production subsidiary, with Petronas Dagangan and Petronas Chemicals handling marketing and petrochemicals, so each business unit runs its own sites.
Petronas was established and incorporated on 17 August 1974 under the Petroleum Development Act, and is vested with all oil and gas resources in Malaysia, so it is the licensor as well as an operator.
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 Petronas. Operators on offshore platforms and at LNG liquefaction trains cover long, multi-level routes with checks at many points. A handheld intrinsically safe phone allows tag scanning, photographs and defect reports inside the classified area. It would support turnaround work at Melaka, Kertih and Pengerang, where large contractor crews work close to live process units.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.

A licence covers upstream and downstream supply; a registration covers downstream subsidiaries only.
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.
Petronas runs a vendor registration and licensing process for suppliers and contractors, and its business units apply their own technical assessment. Details change, so confirm the current registration route and product categories directly with Petronas procurement before offering equipment.
Typical Zone 1 and Zone 2 sites include offshore platforms, gas processing and LNG facilities such as Bintulu, refineries, petrochemical plants and fuel terminals. Classification is site-specific, so ask the operating unit's HSE team for area classification drawings and its rules for portable electronics.
PETRONAS says suppliers apply for a licence or registration through its licensing system. A licence covers upstream and downstream supply, while a registration covers downstream subsidiaries only. Check current requirements with PETRONAS. SAMS has appointed no distributor, and the IS-04Z1 has no certificate yet.
