Refineries
Yanbu hosts three oil refineries; SAMREF was commissioned in 1984 and, like YASREF, is listed at about 400,000 barrels a day.

Intrinsically Safe Mobile Phone in Yanbu
Yanbu Industrial City on the Red Sea coast was established by royal decree in 1975 and is managed by the Royal Commission for Jubail and Yanbu. Its refineries, petrochemical plants and export terminals create Zone 1 and Zone 21 areas for operators and contractors. If you are specifying an intrinsically safe mobile phone for Yanbu Industrial City, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Yanbu Industrial City: rules and approvals
Saudi Arabia's Communications, Space and Technology Commission handles radio type approval; certificates are renewed every two years and European test documents are accepted.
Yanbu Industrial City: geography and layout
The harbour is about 20 km south of Yanbu and is sheltered from the open sea by an offshore barrier reef running parallel to the coast.
Yanbu Industrial City: logistics and access
The port handles about 1,800 vessels and over 84 million tonnes of cargo a year, including crude oil, so marine and jetty work is continuous.
Yanbu Industrial City: logistics and access
Its terminals include general cargo and container, bulk, export refinery and chemical, crude oil, NGL and LPG terminals, so hazardous cargo handling is spread along the coast.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Yanbu Industrial City. Operators at Yanbu move between process units, tank storage and loading areas, and between the two ports. A handheld intrinsically safe device lets them photograph, log and message from within the classified area. The IS-04Z1 is designed for Zone 1 rounds and for turnaround inspection work.

Specifying an intrinsically safe mobile phone for Yanbu
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Yanbu
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Yanbu today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an intrinsically safe mobile phone in Yanbu 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 does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which areas at Yanbu Industrial City would use it?
Likely candidates are refinery process units, petrochemical plants, crude and product storage and loading, marine terminals. 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.
How is Yanbu connected to the east of the country?
The East-West crude pipeline of about 1,200 km can deliver up to 7 million barrels a day to Yanbu from the Eastern Province. Road and air links also exist, but heavy equipment normally arrives through the port; confirm routing and permits with the client.
Which part of Yanbu has the classified areas?
Mostly the industrial city in the south, with its refineries and petrochemical plants, and the port about 20 km south of Yanbu town. Yanbu Al-Bahr in the north is the main residential and commercial area, so offices and hotels are separate from the plants.
Does coastal exposure affect handset choice at Yanbu?
Yes. With a hot desert climate, a July record of 51 C and a Red Sea coast, sealed equipment is favoured. IP68 helps against dust and splash, but heat and salt exposure should be checked against the datasheet. Ingress protection does not replace the Ex marking needed for classified areas.
