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.

Rugged Cell Phone 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. If you are specifying a rugged cell phone for Singapore, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Field notes · Singapore
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 · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Singapore. Singapore has no cool season: ambient sits near 30 °C with humidity above 80 per cent for most of the year, and the Tuas yards add salt and marine conditions. IP68 sealing and a rugged build are the design answer, while the ambient range on the certificate is the compliance figure. IP68 does not give explosion protection.
The route · specification
Specifying a rugged cell phone 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 a rugged cell phone in Singapore 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 rugged cell phone in Singapore 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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
Which Singapore authorities matter for hazardous-area equipment on site?
The Ministry of Manpower covers workplace safety duties for explosive atmospheres, and the Civil Defence Force covers flammable-material storage and dangerous-goods premises. In practice the site operator's own hazardous-area drawings and equipment standard decide what may enter a zone, so check them before shipping anything.
What should a visitor expect when bringing a handheld device onto Jurong Island?
Visitors normally collect a Jurong Island visitor pass at the checkpoint, then receive a separate site pass from the plant they visit. One refinery's published rules ban phones in process and classified areas and ask visitors to declare electronic equipment. Expect similar screening and ask your sponsor in advance.
Why does gas group IIC matter for Jurong Island?
Hydrogen and acetylene, both gas group IIC, are handled on the island next to ethylene oxide in IIB, so a handset rated only to IIB cannot be used in some areas. The IS-04Z1 target is Ex ib IIC. Certification is in progress, so check the final certificate.
