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

Hazardous Area Smartphone 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. 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. This page explains what to look for in a hazardous area smartphone for Jurong Island, and where the IS-04Z1 stands against that list today.

Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

More about Jurong Island that matters for portable equipment
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.
Jurong Island: industry on the ground
Singapore produces no crude oil or feedstock of its own, so Jurong Island plants run on imported material delivered by sea, which makes jetties, tank farms and transfer lines a constant feature of the site.
Jurong Island: infrastructure
The caverns hold about 9.2 million barrels across five isolated storage caverns and store crude oil, condensate, naphtha and gasoil, so vapour-handling surface facilities sit above a very large underground inventory.
Jurong Island: logistics and access
Visitors enter through the Jurong Island Checkpoint, where they exchange an identity card or passport for a Jurong Island visitor pass before travelling on to the plant they are visiting.
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 Jurong Island. Classified areas on Jurong Island include refinery and cracker process units, chemical and petrochemical plants, LNG storage and loading, underground rock cavern storage and marine jetties. Each operator classifies its own areas, not JTC and not SAMS. Obtain the drawings from the plant before choosing equipment.

Questions · Jurong Island
Frequently asked questions
Can we buy a hazardous area smartphone 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 a hazardous area smartphone in Jurong Island cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 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.
