Singapore: geography and layout
Land is scarce, so Singapore stores hydrocarbons underground and builds industry on reclaimed ground: Jurong Island was formed by joining seven islands, and storage caverns free up about 150 acres of surface land.

More about Singapore that matters for portable equipment
Singapore: infrastructure
Natural gas now supplies over 90 percent of Singapore's electricity generation, up from under 20 percent in 2000, and the LNG terminal sends out about 9 million tonnes a year as its average capacity.
Singapore: rules and approvals
The Ministry of Manpower enforces explosive-atmosphere duties under the Workplace Safety and Health Act, while the Singapore Civil Defence Force regulates flammable-materials storage under the Fire Safety Act.
Singapore: logistics and access
Singapore sold 56.775 million tonnes of marine fuel in 2025, making it the largest bunkering port in the world by a wide margin and keeping fuel handling and barge work active around the clock.
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 Singapore. Classified areas in Singapore are concentrated on Jurong Island, Pulau Bukom, the island storage terminals and the Tuas yards, with underground storage at the Jurong Rock Caverns. The operator classifies each of these areas and decides which gas groups apply. SAMS provides no classification and designs the device for a stated one.

Specifying a hazardous area 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 a hazardous area smartphone in Singapore 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 a hazardous area 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.
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 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.
