Intrinsically Safe Smartphone in Singapore LNG
The SLNG Terminal sits on a 40-hectare plot at the southern-most tip of Jurong Island and began commercial operations in May 2013. 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 intrinsically safe smartphone for Singapore LNG Terminal, Jurong Island, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Singapore LNG Terminal, Jurong Island that matters for portable equipment
Singapore LNG Terminal, Jurong Island: infrastructure
The SLNG Terminal has an annualised average gas supply capacity of 9 million tonnes per annum and a peak capacity of up to 11 million tonnes per annum.
Singapore LNG Terminal, Jurong Island: infrastructure
It has two jetties and four storage tanks: three of 180,000 cubic metres and a fourth of 260,000 cubic metres, one of the largest LNG tanks in the world.
Singapore LNG Terminal, Jurong Island: industry on the ground
Natural gas now generates over 90 percent of Singapore's electricity, compared with under 20 percent in 2000, so continuity of send-out is treated as a national energy-security matter.
Singapore LNG Terminal, Jurong Island: projects and investment
SLNG began building a new LNG truck loading facility in August 2025, adding road-tanker loading to the terminal, and describes itself as the owner of Asia's first open-access, multi-user LNG terminal.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 Singapore LNG Terminal, Jurong Island. Rounds at an LNG terminal cover storage tanks, jetties and loading arms, and regasification and send-out equipment. A handheld intrinsically safe phone is intended for readings, photographs and permit steps in those zones. It remains subject to certification, which is in progress, and to SLNG's own rules.

Specifying an intrinsically safe smartphone for Singapore LNG
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 LNG
Frequently asked questions
Can we buy an intrinsically safe 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 intrinsically safe smartphone in Singapore LNG 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
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.
