Role
The terminal supplies about half of Singapore's natural gas for power generation, the remainder coming by pipeline.
Singapore LNG · Ex-proof
Ex-Proof Smartphone in Singapore LNG
The terminal supplies about 50 percent of the natural gas used for Singapore's electricity, with the rest coming by pipeline, and it could cover all present demand if required. It receives, stores and sends out natural gas, mainly for power generation, so tank, jetty and send-out areas are gas-hazardous. If you are specifying an Ex-proof smartphone for Singapore LNG Terminal, Jurong Island, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Singapore LNG Terminal, Jurong Island. The site description puts tank, jetty and send-out areas at Zone 1 and Zone 2, with methane the main gas, which is usually Group IIA. A marking check would compare the device label with the operator's classification. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued.

Questions · Singapore LNG
Frequently asked questions
Can we buy an Ex-proof smartphone in Singapore LNG today?
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.
What does an Ex-proof smartphone in Singapore LNG 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Singapore LNG Terminal, Jurong Island would use it?
Likely candidates are lng storage tanks, lng jetties and loading arms, regasification and send-out. 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.
What hazardous areas does an LNG terminal have?
Typical classified areas include jetty loading arms and manifolds, tank roofs and vent systems, pump and vaporiser areas and send-out metering. Natural gas is typically treated as gas Group IIA, but check the gas group and temperature class against the terminal's own classification.
Will new terminal projects create work for field equipment?
SLNG plans a second offshore terminal by the end of the decade and has expanded the current one in stages. Construction and commissioning phases bring many contractors on site, so approved-equipment lists and induction rules apply from day one; confirm them with the project team.
Which areas of the terminal are classified?
The tank, jetty and send-out areas create Zone 1 and Zone 2 conditions according to the site description, and small-scale reloading is also a gas area. SLNG classifies them. Ask it for the classification drawings and do not assume zones from the general description.
