Island access
Access is restricted to personnel with security passes, and staff travel by ferry, so equipment is usually checked before the crossing.

Explosion-Proof Smartphone in Pulau Bukom Refinery
Pulau Bukom is a restricted-access island about 5 km south of mainland Singapore, home to a 237,000 barrel-per-day refinery and an ethylene cracker. Security passes are issued only to personnel working on the island, and a ferry from the Pasir Panjang ferry terminal, run by Tian San Shipping, serves it, so visitor transfers must be arranged in advance. This page explains what to look for in an explosion proof smartphone for Pulau Bukom, and where the IS-04Z1 stands against that list today.

What Pulau Bukom means for portable equipment
Integrated site
Bukom is linked by subsea pipeline to chemical units on Jurong Island, so contractors may work across both locations.
Field notes · Pulau Bukom
More about Pulau Bukom that matters for portable equipment
Pulau Bukom: industry on the ground
Singapore's energy and chemicals sector is its second-largest manufacturing sector, so the island's refinery and cracker sit within a national cluster of more than 100 chemicals companies.
Pulau Bukom: infrastructure
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.
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.
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 Pulau Bukom. On an island with a refinery, an ethylene cracker and jetties, explosion-proof is usually shorthand. Flameproof Ex d enclosures contain an internal explosion on fixed equipment, while a handheld phone relies on intrinsic safety, which limits energy so no ignition occurs. The IS-04Z1 is designed around the second concept, with certification in progress.

Questions · Pulau Bukom Refinery
Frequently asked questions
Can we buy an explosion proof smartphone in Pulau Bukom Refinery 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 explosion proof smartphone in Pulau Bukom Refinery 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.
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 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.
