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 Ras Tanura. Ras Tanura's classified areas include refinery process units, terminal piers and sea islands, storage tank farms and natural gas liquids fractionation at Ju'aymah. Aramco as operator classifies them; SAMS does not. A buyer should request the area drawings for the specific unit before choosing equipment.

Questions · Ras Tanura
Frequently asked questions
Can we buy a hazardous area 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 a hazardous area mobile phone in Ras Tanura 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 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.
