Hazardous Area Mobile Phone in Senoko Industrial Zone
Senoko is an industrial subzone of Sembawang on Singapore's northern coast, best known for Senoko Power Station. 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. If you are specifying a hazardous area mobile phone 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: 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.
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: infrastructure
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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Senoko. The classified areas here are mainly the power plant's gas and fuel systems and its fuel and storage tanks, not the whole estate. The plant operator classifies them, not SAMS. Hazardous-area exposure outside the power station and fuel storage has not been verified, so a specifier should ask which areas actually apply.

Specifying a hazardous area mobile phone 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 a hazardous area mobile phone 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 a hazardous area mobile phone in Senoko Industrial Zone cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
