Underground storage
Jurong Rock Caverns, 150 metres below ground, can store up to 1.47 million cubic metres (around 9 million barrels) of liquid hydrocarbons, adding below-ground classified areas.

Rugged Mobile Phone in Jurong Island
One refinery on the island forbids mobile phones and other electrical or electronic equipment in its process plant and classified hazardous areas, and requires visitors to declare cameras, computers and laptops at security. 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 a rugged mobile phone for Jurong Island, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Jurong Island. Singapore is hot and humid, and an island of reclaimed land with marine jetties adds exposure to splash and salt air. IP68 on the IS-04Z1 helps against water and dust ingress. It is not explosion protection, and the datasheet limits still need to be checked for tropical conditions.

Specifying a rugged mobile phone for Jurong Island
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 · Jurong Island
Frequently asked questions
Can we buy a rugged 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 a rugged mobile phone 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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
