The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Keppel Shipyard (now Seatrium yards), Singapore. Classified areas at the yards include vessel tank and cargo spaces, offshore unit and FPSO conversion, paint and solvent areas and dry dock work. They change with the job, and permits and gas-free certification are handled per vessel. The yard classifies, not SAMS, so ask the yard safety department.

Questions · Keppel Shipyard
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
