Ex-Proof Smartphone Distributor in Senoko Industrial Zone
Senoko is an industrial subzone of Sembawang on Singapore's northern coast, best known for Senoko Power Station. Classified areas centre on the power station's gas systems and on fuel storage tank leasing and terminal services, not on the whole estate. An Ex-proof smartphone distributor in Senoko would carry the IS-04Z1 to these buyers once certification completes.

Field notes · Senoko
More about Senoko that matters for portable equipment
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.
Senoko: industry on the ground
Natural gas has replaced crude oil as the main fuel since 1992, with fuel oil kept as a back-up, and stage III boilers were modified with gas burners to burn either fuel.
Senoko: industry on the ground
Senoko is best known for two uses, its power station and a fishery port, so large power plant and wholesale seafood handling share the same stretch of Sembawang's northern coastline.
Senoko: climate and equipment wear
Equatorial heat and humidity, with frequent heavy showers, are constant on this northern coast and affect outdoor switchyards, fuel tanks and gas metering stations.
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 Senoko. A marking check at the power station would focus on the gas fuel systems and fuel tanks, where natural gas is typically IIA and diesel vapour is a flammable liquid hazard. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued. The operator's classification drawings say which gas group and temperature class apply.
The route · distribution
Distributing the IS-04Z1 in Senoko Industrial Zone
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Senoko. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device 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 Ex-proof smartphone in Senoko Industrial Zone 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 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 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 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.
