Singapore: projects and investment
SLNG plans a second LNG terminal offshore, slated to operate by the end of the decade, in addition to the existing Jurong Island terminal, so new gas-handling sites are expected over the coming years.

Explosion-Proof Smartphone in Singapore
The IS-04Z1 is an intrinsically safe Zone 1 and Zone 21 handset for people who work inside classified areas on Jurong Island, at Pulau Bukom and around the Tuas terminals: process operators, inspection and maintenance engineers, turnaround crews and the WSH and IT teams who equip them. This page explains what to look for in an explosion proof smartphone for Singapore, and where the IS-04Z1 stands against that list today.

More about Singapore that matters for portable equipment
Singapore: rules and approvals
IMDA registers telecommunications equipment under a supplier's declaration approach. Cellular mobile devices, including 5G and LTE, fall under Simplified Equipment Registration, while base stations and similar higher-risk products need a recognised certification body.
Singapore: rules and approvals
An IMDA equipment registration is valid for five years, renewal is filed through the GoBusiness portal at least two months before expiry, and suppliers must keep test reports and technical files for five years.
Singapore: logistics and access
Tuas Port opened on 1 September 2022 and is planned to reach 65 million TEU of annual handling capacity in the 2040s, which concentrates future cargo flows in the far west of the island.
The term · explosion proof
What “explosion proof” means for a smartphone
“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 Singapore. Explosion-proof is used loosely on the island, but the plants hold varied atmospheres. A flameproof Ex d enclosure suits fixed equipment, while intrinsic safety, the protection concept of the IS-04Z1, limits the energy of a handheld. On Jurong Island the practical question is which concept a handset uses for hydrogen or acetylene areas.

Specifying an explosion proof smartphone for Singapore
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- 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 · Singapore
Frequently asked questions
Can we buy an explosion proof smartphone in Singapore today?
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.
What does an explosion proof smartphone in Singapore cost?
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.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
Which sites in Singapore does this cover?
The market guide for Singapore covers Jurong Island, Pulau Bukom, Seraya and Merbau, Pulau Sebarok and Pulau Busing, among others. Site-level pages are linked below.
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.
Are ATEX and IECEx markings both understood in Singapore?
Singapore adopts IEC 60079 as SS EN 60079, and both IECEx and ATEX certificates are built on that technical base. Many operators accept either, but an individual refinery or yard may name one scheme in its specification, so confirm with the operator's HSE or instrumentation team.
Do phones and tablets sold in Singapore need IMDA registration?
Cellular mobile devices are generally registered with IMDA under the Simplified Equipment Registration route, which relies on a supplier's declaration of conformity. The registration is valid for five years, and the registering supplier is typically a local entity. Confirm the exact route for a specific model with IMDA or a local compliance adviser.
How does the IS-04Z1 cope with island and boat-access sites such as Bukom?
The design pairs a 4,000 mAh battery with IP68 sealing so the unit lasts through a shift where a spare may be a boat away. Charging stays in a safe area. Test battery life on a typical round and confirm access rules with the island operator.
