Intrinsically Safe Smartphone Distributor in Tuas Industrial Zone
Tuas is a largely industrial planning area of 47.7 square kilometres in far western Singapore, with shipyards, heavy industry, a chemicals hub and the new Tuas Port. The Malaysia-Singapore Second Link opened on 2 January 1998 via Tuas, and the AYE and PIE expressways connect Tuas to the rest of Singapore. An intrinsically safe smartphone distributor in Tuas would carry the IS-04Z1 to these buyers once certification completes.

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.
The route · distribution
Distributing the IS-04Z1 in Tuas Industrial Zone
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Tuas. 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 Tuas.
- 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 · Tuas Industrial Zone
Frequently asked questions
Can we buy an intrinsically safe smartphone 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 smartphone in Tuas 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 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.
How do I become a SAMS distributor for Tuas?
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 Tuas.
What hazardous areas are found in Tuas?
Mostly shipyards, chemical and fuel handling sites, a renewable diesel plant and waste-to-energy facilities. Classified areas are limited to specific plants rather than the whole zone, so ask each tenant for its area classification.
Is Tuas Port expected to change access and logistics?
Yes. The port will grow in phases through the 2040s and PSA plans to relocate city terminals into it, so traffic and construction will increase. Contractors should check gate and escort rules with the host site.
Is all of Tuas treated as a hazardous area?
No. Classified areas arise mainly at shipyards, fuel and chemical handling and process plants, and which tenants have them has not been verified individually. Ask each tenant for its area classification, and confirm with the site operator.
