Industrial use
Tuas was resettled in the 1970s and developed for industry; heavy industry is present, though less than on Jurong Island.

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 Tuas. Tuas work is dispersed: yards, fabrication shops and fuel handling lie across a large estate. A handheld intrinsically safe phone is intended to let crews carry photographs, checklists and permits through classified spots in shipyards or fuel areas, if certified and accepted. Certification is in progress.

Specifying an intrinsically safe mobile phone for Tuas 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 · Tuas Industrial Zone
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Tuas 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 mobile phone in Tuas 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.
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 Tuas would use it?
Likely candidates are shipyard and drydock work, dangerous-goods chemical blending and storage, fabrication and coating shops. 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.
How do equipment suppliers reach Tuas sites?
By road via the AYE and PIE, and by sea to the port. Most customers are inside controlled industrial sites with their own gates, so deliveries are usually scheduled and checked in advance.
Are there dust hazards as well as gas?
Waste-to-energy and some manufacturing processes can handle combustible dusts or fine fuels, which may be classified as dust zones. Whether a given building has dust zones depends on the process; ask the operator for dust classification.
Does the Tuas Megaport change anything for device buyers?
The port began operating in 2021 and is due to be fully completed by 2040, so activity is growing. Port areas where fuel or cargo vapours occur would be classified by the operator. This page does not verify any port classification, so ask the operator directly.
