Explosion-Proof 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 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. This page explains what to look for in an explosion proof smartphone for Jurong Island, and where the IS-04Z1 stands against that list today.

WhereJurong Island
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Jurong Island: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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: 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.
Jurong Island: rules and approvals
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Jurong Island. Refinery and cracker units, chemical plants, LNG storage and marine jetties are all described loosely as explosion-proof areas. The real concepts are flameproof Ex d for fixed gear and intrinsic safety for handhelds. The IS-04Z1 is designed for intrinsic safety, so each plant should say which concept a task needs.

Specifying an explosion proof smartphone 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.

- 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 an explosion proof smartphone in Jurong Island today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an explosion proof 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
