The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Keppel Shipyard (now Seatrium yards), Singapore. In a shipyard, explosion-proof is a loose label for tank, cargo space and paint-area work. Fixed equipment may be flameproof Ex d, while handhelds used inside tanks are more likely to rely on intrinsic safety. The IS-04Z1 is designed for intrinsic safety, so state the concept needed for each task.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy an explosion proof mobile phone in Keppel 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 explosion proof mobile phone in Keppel Shipyard 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Which areas at Keppel Shipyard (now Seatrium yards), Singapore would use it?
Likely candidates are vessel tank and cargo spaces, offshore unit conversion, paint and solvent areas, dry dock work. 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.
Does the work differ between FPSO conversion and ordinary repair?
Conversion projects involve large process and tank systems that become classified areas when commissioned, while repair work is more tank-by-tank and short term. Expect tighter control of electronics on conversion hulls close to hydrocarbon systems. The vessel owner and yard HSE team set the rules for each project.
Is Keppel Shipyard still operating under the Keppel name?
Keppel's offshore and marine yards are now part of Seatrium, formed in 2023 from Sembcorp Marine and Keppel Offshore and Marine. Former Keppel yard sites in Singapore are now listed under Seatrium, so use that name when registering for contractor access or supplier approval.
Are older Keppel yard references still correct?
No. Seatrium was formed in 2023 and Keppel's yards now operate under it, and the Gul yard was sold to ST Engineering. Use current names when contacting yards. Details of individual Seatrium yards were not verified, so ask the company which yard serves your project.
