Intrinsically Safe Smartphone Distributor in Senoko Industrial Zone
Senoko is an industrial subzone of Sembawang on Singapore's northern coast, best known for Senoko Power Station. Its authorised capacity is 2,800 megawatts from seven operating units, and it runs mainly as a combined-cycle gas plant, so gas-turbine halls and fuel systems form its main classified areas. Distribution partners for Senoko are being identified ahead of the Q4 2026 launch of the IS-04Z1.

Short answer. Senoko 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

More about Senoko that matters for portable equipment
Senoko: industry on the ground
Senoko Power Station is the largest power station in Singapore and was commissioned in 1976, after planning began in the early 1970s under the Public Utilities Board.
Senoko: industry on the ground
Natural gas supplies over 90 percent of Singapore's electricity, up from less than 20 percent in 2000, which is why large gas-fired plants such as Senoko dominate the local hazardous-area picture.
Senoko: infrastructure
Combined-cycle units 6 and 7, rated at 431 megawatts each, were completed by 2012 by repowering the second oil-fired steam stage, while units 3 to 5 at 365 megawatts each followed by 2004.
Senoko: background
The station stands on the site of a former British naval base in Sembawang on Singapore's northern coast, so the shoreline is a mixture of old naval and new industrial land.
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 Senoko. Plant rounds through gas receiving, fuel storage and turbine halls are walking inspections with readings, photos and permits to log. A handheld intrinsically safe phone is intended for that routine, if certification is completed and the owner accepts it. Outage periods with many contractors add to the case for a managed device.
The route · distribution
Distributing the IS-04Z1 in Senoko Industrial Zone
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Senoko yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Senoko.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Senoko Industrial Zone
Frequently asked questions
Can we buy an intrinsically safe smartphone in Senoko Industrial Zone 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 intrinsically safe smartphone in Senoko Industrial Zone cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 Senoko would use it?
Likely candidates are power plant gas and fuel systems, fuel storage tanks and terminal services. 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 Senoko?
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 Senoko.
Is the whole Senoko estate a hazardous area?
No. Classified areas are concentrated at the power station's gas systems and at fuel storage, not across the whole industrial zone. Other tenants may have none at all. Ask the specific site for its area classification drawing before choosing equipment.
What type of hazardous areas does a gas-fired power station have?
Typical examples are gas pressure-reduction and metering stations, gas turbine enclosures, fuel oil storage and pump areas, and battery or hydrogen-related rooms. Most are Zone 2 in normal operation, but Zone 1 can occur around specific equipment, so confirm with the plant.
Who approves contractor devices at the power station?
The plant operator runs its own contractor and equipment approvals, and SAMS has no role in them. Send its procurement and HSE teams the IS-04Z1 datasheet and target marking, noting that certification is in progress and no certificate has been issued.
