A Zone 1 and Zone 21 handset for Malaysian crews: process and maintenance technicians at Pengerang and Kertih, LNG operators at Bintulu, offshore production staff off Miri and Kimanis, and the safety and telecoms people who issue their equipment. This page explains what to look for in an explosion proof cell phone for Malaysia, 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 Malaysia: 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 |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Malaysia: Pengerang, Johor, Kertih, Terengganu, Gebeng, Pahang | 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.
The main operators, industrial areas and sites that the SAMS Malaysia market guide covers.
Petronas is a vertically integrated group covering exploration, refining, distribution, power generation and trading, with subsidiaries such as Petronas Carigali for upstream, Petronas Chemicals for petrochemicals and Petronas Dagangan for marketing.
Oil exploration in Sarawak started at Miri, where Shell drilled the first well in 1910; the well became known as the Grand Old Lady, which gives the north-west of Borneo a long upstream history.
Malaysia Petroleum Management, a division of Petronas, oversees the whole lifecycle of the country's upstream oil and gas assets, so site rules for field equipment are typically passed down through the operator.
Domestic oil production peaked in 2016 as large shallow fields matured, while natural gas plays an outsized role in energy planning, which keeps gas processing and LNG handling central to hazardous-area work.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Malaysia. At Pengerang or Kertih an engineer may call any approved device explosion proof, yet the concepts differ. Flameproof enclosures suit motors and heavy fixtures, while the IS-04Z1 uses intrinsic safety, limiting stored and delivered energy. That fits crews who carry a handset through cracker units, LNG jetties at Bintulu and offshore platforms off Miri and Kimanis.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
The market guide for Malaysia covers Pengerang, Johor, Kertih, Terengganu, Gebeng, Pahang, Bintulu, Sarawak, among others. Site-level pages are linked below.
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.
Normally the plant operator decides, through its HSE and instrumentation teams, usually by asking for ATEX or IECEx documentation against IEC 60079. Mobile radio approval is a separate matter handled under MCMC rules. Confirm both with the operator and your importer before ordering.
Sarawak's Miri area has the oldest upstream history, and Petronas Carigali runs the country's main exploration and production business. Gas processing and LNG are central to energy planning. Exact field and plant lists change, so confirm current sites with your client.
It is designed for Zone 1 with IP68 sealing and a 4,000 mAh battery, but offshore use depends on the platform's own classification and the certificate's ambient range. Crews cannot replace kit mid-hitch, so confirm battery plans, charging in safe areas and approval with the platform operator.
