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. If you are specifying an intrinsically safe mobile phone for Malaysia, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
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. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.
Operators and classified areas drawn from the SAMS Malaysia market guide.
The Malaysian Communications and Multimedia Commission (MCMC), based in Cyberjaya, regulates communications under the Communications and Multimedia Act 1998, so radio and mobile-device rules sit with a different body from Ex rules.
Electrical and electronic products, petroleum products, LNG, chemicals and palm-oil-based manufactures are among the main exports, so processing sites range from petrochemical units to palm-oil mills.
Energy supply is regulated by the Energy Commission (Suruhanjaya Tenaga) and the Department of Electricity and Gas Supply, under laws that include the 1974 Petroleum Development Act and the 1993 Gas Supply Acts.
PETRONAS describes its Pengerang Integrated Complex in Johor as one of Southeast Asia's largest integrated petrochemical facilities, valued at USD 27 billion and located within the Pengerang Integrated Petroleum Complex.
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 Malaysia. Technicians at Kertih, Pengerang and Bintulu make long outdoor rounds and turnaround inspections, and offshore crews spend a hitch on platforms reached by helicopter or boat. An intrinsically safe handheld lets one device carry the camera, GNSS and work-order app into classified ground, and nothing can be replaced mid-hitch if it is not practical to carry spares.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.

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.
Malaysia is hot and humid, so check the stated operating temperature range, ingress protection rating and battery behaviour at the top of that range. Offshore and coastal sites also add salt-laden air, which makes sealed connectors and charging contacts worth checking.
Petronas and its operating companies typically apply their own site procedures on top of national law, including permit-to-work and device registration. Requirements vary by facility and contractor, so ask the site HSE office for its current device and induction rules.
Radio equipment is regulated separately from explosion protection. The programme lists MCMC certification through SIRIM QAS for the communications side, alongside IECEx for the hazardous area side, and both are in progress. Check with your supplier and the site operator which evidence your site requires before enrolling any device.
