Basic worker residential blocks at Benoi Sector and Pioneer Road house many people who work in the western yards, so shift changes concentrate traffic in that corridor. Repair, conversion and newbuild work brings Zone 1 conditions into tanks, cargo spaces and paint areas. If you are specifying an Ex-proof mobile phone for Singapore shipyards, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 shipyards. The yards report Zone 1 conditions in tank spaces, dry dock and repair work, paint and coating shops and offshore conversion. A marking check would compare gas group and temperature class with the cargo or solvent in each space. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued.

Questions · Singapore Shipyard
Frequently asked questions
Can we buy an Ex-proof mobile phone in Singapore Shipyard 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 mobile phone in Singapore Shipyard 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 shipyards would use it?
Likely candidates are vessel tank spaces, dry dock and repair work, paint and coating shops, offshore 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.
Do large docks create special conditions?
Large graving docks hold very big vessels and many contractors at once, so crowding, crane lifts and hot work overlap. Hazardous-area controls are managed per vessel by the yard's safety team and the owner's representative.
Which Singapore shipyards are major sites for Zone 1 work?
Seatrium's yards at Admiralty, Benoi, Pioneer, Tuas and Tuas Boulevard are the large repair and conversion sites, and other yards operate in the Jurong area. Zone 1 conditions arise inside tanks and pump rooms during repair and coating work.
Do gas-free procedures replace the need for certified equipment?
Not automatically. Tank entry and hot work normally follow per-vessel gas-free and permit procedures set by the yard, and some yards still require certified equipment in certain spaces. The IS-04Z1 has no certificate yet. Ask the yard safety department which rule applies.
