Integrated site
Bukom is linked by subsea pipeline to chemical units on Jurong Island, so contractors may work across both locations.

Ex-Proof Mobile Phone in Pulau Bukom Refinery
The Bukom and Jurong Island sites are joined by a 5 km subsea pipeline, which carries product between islands and reduces ship-to-shore transfers. Since April 2025 the complex has been owned by CAPGC and operated as the Aster Energy and Chemicals Park, so process units create Zone 1 areas. If you are specifying an Ex-proof mobile phone for Pulau Bukom, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Pulau Bukom that matters for portable equipment
Pulau Bukom: background
Pulau Bukom has been the site of Singapore's first oil refinery since 1961, and the island has hosted refining, trading and related services for more than six decades.
Pulau Bukom: who works there
The Shell stake in the park was acquired in April 2025 by CAPGC, a joint venture between a Chandra Asri subsidiary and a Glencore subsidiary, and the site was renamed Aster Energy and Chemicals Park.
Pulau Bukom: who works there
Aster Bukom concentrates on refining and ethylene production, while Aster's Jurong Island complex makes chemicals, so the two sites act as one integrated operation.
Pulau Bukom: climate and equipment wear
Singapore's equatorial climate gives consistent heat and humidity with frequent heavy showers, which affects open-air process plant, tank farms and jetties year round.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Pulau Bukom. A marking check for process units classed as Zone 1 would start with the equipment protection level, gas group and temperature class on the label. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, which is not yet issued. Hydrocarbon duties often involve IIA or IIB gases, and ethylene work can call for IIB or higher; the operator confirms the requirement.

Specifying an Ex-proof mobile phone for Pulau Bukom Refinery
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 · Pulau Bukom Refinery
Frequently asked questions
Can we buy an Ex-proof mobile phone in Pulau Bukom Refinery 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 Ex-proof mobile phone in Pulau Bukom Refinery 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Pulau Bukom would use it?
Likely candidates are refinery process units, ethylene cracker, crude and product tank farms, jetties. 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.
Is the Bukom site connected to Jurong Island?
Yes. A 5 km subsea pipeline links Aster Bukom to Aster's chemical complex on Jurong Island, so the two sites run as one integrated operation. Expect shared safety standards between sites, but confirm site-specific rules with each location.
What process areas are on Bukom?
Aster describes Bukom as a fully integrated site focused on refining and ethylene production. That means crude units, cracker furnaces, tank farms and jetties, where Zone 1 and Zone 2 gas areas are typical. Exact zoning is set by the operator's area classification.
How does island access affect bringing handhelds to Bukom?
The site restricts access to personnel with security passes, and staff travel by ferry, so equipment is usually checked before the crossing. Ask the operator's security and HSE teams what device checks apply, and plan enrolment and charging before travel. Confirm the current process with the site operator.
