Hazardous Area Mobile Phone in Singapore Petrochemical
Singapore's petrochemical sector is concentrated on Jurong Island, a roughly 3,000-hectare park with over 100 companies, and on Pulau Bukom. Jurong Rock Caverns store crude oil, condensate, naphtha and gasoil underground, giving petrochemical plants on Jurong Island a large buffer of feedstock close by. This page explains what to look for in a hazardous area mobile phone for Singapore petrochemical sector, and where the IS-04Z1 stands against that list today.

More about Singapore petrochemical sector that matters for portable equipment
Singapore petrochemical sector: infrastructure
Natural gas is the main fuel for Singapore's power generation, and the LNG terminal on Jurong Island can supply about 9 million tonnes a year on average to power and industry.
Singapore petrochemical sector: industry on the ground
Energy and chemicals is Singapore's second-largest manufacturing sector, with more than 100 global chemicals companies, and the country is positioned as a hub for petrochemical production and trading.
Singapore petrochemical sector: infrastructure
Aster's Bukom complex produces ethylene and refined products and is linked to its Jurong Island chemical complex by a 5 km subsea pipeline.
Singapore petrochemical sector: industry on the ground
A world-scale renewable diesel plant using palm oil as feedstock was completed in Tuas in 2010, showing that petrochemical-type processing also exists outside Jurong Island.
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 Singapore petrochemical sector. Classified areas in this sector are cracker process units, chemical derivative plants, tank farms and polymer handling and dust areas. Each plant owner classifies its own areas, and the island has more than 100 companies. SAMS does not classify, so a specifier should obtain the relevant plant's documents.

Specifying a hazardous area mobile phone for Singapore Petrochemical
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 · Singapore Petrochemical
Frequently asked questions
Can we buy a hazardous area mobile phone in Singapore Petrochemical 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 a hazardous area mobile phone in Singapore Petrochemical 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.
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 Singapore petrochemical sector would use it?
Likely candidates are cracker process units, chemical derivative plants, tank farms, polymer handling and dust areas. 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.
What hazardous areas does a petrochemical complex have?
Common examples include cracker and reactor areas, pump and compressor houses, tank farms, jetties and polymer or powder handling, where dust zones can also arise. Zone 1 is common around seals and vents, but classification is set per plant, so ask for the area drawing.
How is Singapore's petrochemical feedstock supplied?
Singapore has no crude oil or feedstock of its own, so material arrives by sea, is stored in tank farms and caverns, and is sent through pipelines. This creates busy jetty and transfer areas where equipment control is strict.
Can one approval be reused between plants on Jurong Island?
Not safely. Each plant runs its own contractor and equipment approvals, so acceptance at one plant does not carry over to a neighbour. Prepare a datasheet pack for each. Confirm requirements with the site operator at every plant.
