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

Intrinsically Safe Smartphone Distributor 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. 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. Distribution partners for Pulau Bukom are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WherePulau Bukom Refinery
Short answer. Pulau Bukom has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Pulau Bukom
More about Pulau Bukom that matters for portable equipment
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.
Pulau Bukom: logistics and access
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.
Pulau Bukom: geography and layout
Pulau Bukom is a restricted-access island of about 145 hectares, roughly 5 km south of mainland Singapore in the Singapore Strait, with a small companion islet to its south.
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.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Pulau Bukom. Rounds across tank farms, cracker units and jetties involve a lot of walking, photographing and logging in classified areas. A handheld intrinsically safe device is intended to let an operator capture readings and images. That depends on certification, which is in progress, and on the operator's own rules.

Questions · Pulau Bukom Refinery
Frequently asked questions
Can we buy an intrinsically safe smartphone 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 intrinsically safe 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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is 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.
How do I become a SAMS distributor for Pulau Bukom?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Pulau Bukom.
Who operates the Pulau Bukom complex now?
The complex is operated as Aster Bukom, part of Aster Chemicals and Energy, which was acquired in April 2025 through CAPGC, a joint venture between a Chandra Asri subsidiary and a Glencore subsidiary. Use the Aster name when asking about supplier registration.
How do people and equipment reach an island refinery?
Bukom is an island, so access is typically arranged through the operator, with pass checks before travel. Equipment usually has to be declared and approved in advance, so plan lead time for inspection and any device certification review.
Who decides whether a phone is acceptable inside Bukom's process units?
The operator, now the Aster site owner, sets contractor and equipment approvals and classifies its own areas. SAMS cannot approve a device for a site. Share the IS-04Z1 datasheet and marking target with its procurement and HSE teams, and note that certification is still in progress.
