Ex-Proof Smartphone in Singapore Marine
Workplace safety in yards and on vessels falls under MOM's Workplace Safety and Health framework, and marine bunkering facilities are named among Singapore's common explosive-atmosphere locations. Tank work, repair and conversion create Zone 1 conditions on vessels. This page explains what to look for in an Ex-proof smartphone for Singapore marine and shipyard sector, and where the IS-04Z1 stands against that list today.

Singapore marine and shipyard sector: logistics and access
Tuas Port, opened in September 2022, is planned to handle 65 million TEU a year in the 2040s, moving more container traffic to the western end of the island.
Singapore marine and shipyard sector: who works there
Seatrium organises its business into oil and gas newbuilds and conversions, renewables and new energies, specialised shipbuilding, and repairs and upgrades, all based around Singapore.
Singapore marine and shipyard sector: logistics and access
Singapore sold 56.775 million tonnes of marine fuel in 2025, the largest bunkering volume of any port, so tanker, barge and fuel-transfer operations are a daily feature of its waters.
Singapore marine and shipyard sector: infrastructure
Seatrium's Tuas Boulevard Yard has a graving dock about 350 metres long and 66 metres wide, which can take very large tankers and floating production units.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Singapore marine and shipyard sector. A marking check for vessel tank and cargo spaces, described as Zone 1, would compare gas group and temperature class with the cargo history of the tank. Paint and coating vapours add solvent atmospheres. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued, and the yard decides.

Specifying an Ex-proof smartphone for Singapore Marine
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

Questions · Singapore Marine
Frequently asked questions
Can we buy an Ex-proof smartphone in Singapore Marine today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an Ex-proof smartphone in Singapore Marine 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 Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Singapore marine and shipyard sector would use it?
Likely candidates are vessel tank and cargo spaces, repair and conversion work, paint and coating areas, offshore unit conversion. 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 makes marine hazardous areas different from onshore plants?
Zones move with the vessel's cargo, tank status and gas-free certification, so a space may be classified one day and safe the next. Always check the vessel's permit and gas-freeing status rather than relying on a fixed plan.
How can a supplier get onto a yard as a contractor?
Seatrium publishes its yard addresses, but access is normally arranged through a named project sponsor with induction, site pass and permit-to-work steps. Ask the sponsor which equipment certifications they accept before you ship devices.
Is a phone allowed inside a cargo tank on a vessel under repair?
Tank entry normally follows per-vessel gas-free and permit procedures set by the yard, and Zone 1 conditions are assumed in tank spaces. Only equipment with suitable certification would be considered, and the IS-04Z1 is not yet certified. Ask the yard safety team.
