Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Tuas: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Tuas
More about Tuas that matters for portable equipment
Tuas: background
Tuas was swamp and then a fishing village before being resettled in the 1970s and developed for industry, with land reclaimed off the coast from the 1980s and still expanding.
Tuas: people and language
Tuas is mostly industrial with few homes, so workers live in basic residential blocks at Benoi Sector and Pioneer Road or travel in from other parts of Singapore.
Tuas: logistics and access
Tuas Port opened on 1 September 2022 and will span about 1,337 hectares with 66 berths over 26 kilometres once complete, which is shifting container operations towards the far west of the island.
Tuas: geography and layout
Tuas is bounded by the Western Water Catchment to the north, Pioneer to the east and the Straits of Johor to the west, and it has six subzones including Tuas Bay and Tuas View.
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 Tuas. Which Tuas tenants hold classified areas has not been verified individually, and the estate is far from uniformly hazardous. Areas arise at shipyard and drydock work, fuel and chemical handling and fabrication and coating shops. The tenant classifies them, not SAMS, so ask each one before assuming a zone.

- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Tuas Industrial Zone
Frequently asked questions
Can we buy a hazardous area smartphone in Tuas Industrial Zone 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 Tuas Industrial Zone 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 Tuas would use it?
Likely candidates are shipyard and drydock work, dangerous-goods chemical blending and storage, fabrication and coating shops. 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.
How do equipment suppliers reach Tuas sites?
By road via the AYE and PIE, and by sea to the port. Most customers are inside controlled industrial sites with their own gates, so deliveries are usually scheduled and checked in advance.
Are there dust hazards as well as gas?
Waste-to-energy and some manufacturing processes can handle combustible dusts or fine fuels, which may be classified as dust zones. Whether a given building has dust zones depends on the process; ask the operator for dust classification.
Does the Tuas Megaport change anything for device buyers?
The port began operating in 2021 and is due to be fully completed by 2040, so activity is growing. Port areas where fuel or cargo vapours occur would be classified by the operator. This page does not verify any port classification, so ask the operator directly.
