The refinery was established in 1939 and expanded substantially after the Second World War, so equipment and layouts range from very old to recently modernised.
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 Ras Tanura. Storage tank farms and loading piers handle fuels and crude, where lower gas groups often apply, while fractionation of natural gas liquids may differ. A marking check should read the gas group and temperature class from Aramco's classification. The IS-04Z1 target marking is II 2 G Ex ib IIC T4.

- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1

Questions · Ras Tanura
Frequently asked questions
Can we buy an Ex-proof mobile phone in Ras Tanura 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 Ras Tanura cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
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 Ras Tanura would use it?
Likely candidates are refinery process units, crude export terminal piers and sea islands, storage tank farms, natural gas liquids fractionation (ju'aymah). 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.
Who sets equipment rules at Ras Tanura?
Saudi Aramco manages and operates the industrial infrastructure, so its safety and approval procedures apply to contractors working on the refinery, terminal and gas plant. Check the current vendor and equipment-approval requirements with the Aramco project owner or the main contractor.
Are Ras Tanura facilities old or new?
Both. The refinery dates from 1939 and has been expanded many times, so older plant sits alongside modern units. For handheld devices, ask for the area classification and equipment group for each unit, since gas groups and temperature classes can differ between old and new areas.
Can a handset be used on the piers and sea islands?
Only if its protection suits the classified area there, and if the operator permits it. The piers and sea islands handle crude, where Aramco classifies the area. Ask Aramco or the site contractor for the zone and the device approval route before any handset goes near a loading point.
