Explosion-Proof Smartphone in Senoko Industrial Zone
Senoko is an industrial subzone of Sembawang on Singapore's northern coast, best known for Senoko Power Station. 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. If you are specifying an explosion proof smartphone for Senoko, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Senoko that matters for portable equipment
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.
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.
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 Senoko. At a gas and diesel power station the phrase explosion-proof can mislead. Flameproof Ex d housings suit fixed items such as motors and junction boxes, while a handheld phone relies on intrinsic safety to keep energy below ignition level. The IS-04Z1 is designed around intrinsic safety, with certification still in progress.

Specifying an explosion proof smartphone for Senoko Industrial Zone
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 · Senoko Industrial Zone
Frequently asked questions
Can we buy an explosion proof smartphone in Senoko Industrial Zone today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an explosion 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.
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 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.
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.
When are outages most likely to need extra field devices?
Combined-cycle units are taken offline for planned inspections, and contractor numbers rise during those windows. Dates are set by the operator and the grid, so ask the plant's maintenance planner about the outage calendar and the approved-equipment list.
Does the fuel mix change the equipment requirement?
Natural gas has been the main fuel since 1992, with fuel oil as a back-up. Gas groups and temperature classes differ between natural gas and oil vapour, so devices should be matched to the gas group and temperature class stated in the plant's area classification.
Is the whole Senoko estate a hazardous area?
No. The classified areas are mostly the gas and fuel systems and fuel tanks at the power station, not the estate as a whole. Other tenants have not been checked here. Ask the relevant operator for its classification before assuming a zone, and confirm with the site operator.
