Energy and water security
JTC states that the island also hosts power generation and desalination plants and supports Singapore's natural gas supply, so work there covers utilities as well as process plants.

Intrinsically Safe Mobile Phone in Jurong Island
Jurong Island is Singapore's integrated energy and chemicals park of about 3,000 hectares, formed from seven small islands and developed by JTC. It hosts over 100 global companies in refining, olefins and chemical manufacturing, so gas and vapour (Zone 1) areas are widespread. If you are specifying an intrinsically safe mobile phone for Jurong Island, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Dense cluster
Many operators sit close together, so contractors often move between plants that each run separate permit and approval systems.

Jurong Island: infrastructure
Jurong Rock Caverns, completed in 2014, were the first commercial underground liquid-hydrocarbon storage in Southeast Asia, sited under the seabed of Banyan Basin about 120 metres (390 feet) below sea level.
Jurong Island: geography and layout
The island was created by reclaiming and amalgamating seven southern offshore islands, and its land area was tripled from the original 1,000 hectares, as described by the Prime Minister at the caverns' opening in 2014.
Jurong Island: people and language
The nearest rail link is Lakeside MRT station; public bus 98 runs to the Jurong Island Checkpoint, and some plants run private shuttle buses between the checkpoint and their premises.
Jurong Island: industry on the ground
Singapore Refining Company runs a refinery on Jurong Island able to process 290,000 barrels of crude a day, producing fuel products and chemical feedstocks for domestic and export markets.
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 Jurong Island. Contractors on Jurong Island often move between plants with separate permit systems, making rounds, inspections and shutdown work in different Zone 1 areas. A handheld intrinsically safe handset lets them record findings and photograph equipment in each. The IS-04Z1 is designed for such use, with a 50 MP camera.

Questions · Jurong Island
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Jurong Island 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 mobile phone in Jurong Island 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 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 Jurong Island would use it?
Likely candidates are refinery and cracker process units, chemical and petrochemical plants, lng storage and loading, underground rock cavern storage. 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.
Can I bring a mobile phone into a plant on Jurong Island?
Usually not into process or classified areas unless the equipment is approved for the zone and the operator permits it. One refinery on the island publishes a ban on phones and other electronic equipment in those areas. Ask your site sponsor which devices are accepted and whether a permit is needed.
How large is refining activity on Jurong Island?
One refinery on the island states a crude processing capacity of 290,000 barrels a day, and other chemical and refining operators share the same island. Because feedstock arrives by sea, expect busy jetty, tank and pipeline areas where Zone 1 and Zone 2 conditions are common.
Can contractors move one device between plants?
Not automatically. Each plant runs its own contractor and equipment approvals and permit system, so a device accepted at one plant may need separate approval at another. Ask each plant's HSE team for its process, and plan enrolment and permits per client.
