Refinery modernisation
The modernised refinery is ramping up towards about 405,000 barrels a day, and contractors were still completing final units into late 2025 and early 2026.

Intrinsically Safe Smartphone in Sitra
Sitra is an island on the east side of Bahrain Island whose northern part is an industrial area. It hosts the Bapco Sitra refinery, whose $7 billion modernisation was inaugurated in December 2024, and the GARMCO aluminium rolling mill, so refinery and heavy-industry hazardous areas are present. If you are specifying an intrinsically safe smartphone for Sitra, Bahrain, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

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 Sitra, Bahrain. Turnaround and commissioning work at a refinery means many people walking process units, tank farms and the gas pipeline terminus with phones for photos, permits and checklists. An intrinsically safe handheld avoids carrying an ordinary phone into classified areas. The IS-04Z1 is designed for that role once certified.

Specifying an intrinsically safe smartphone for Sitra
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 · Sitra
Frequently asked questions
Can we buy an intrinsically safe smartphone in Sitra today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an intrinsically safe smartphone in Sitra 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 Sitra, Bahrain would use it?
Likely candidates are refinery process units, crude and product storage, hydrogen and hydrocracking units, sulphur recovery units. 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.
Is the refinery still being modernised?
Construction of a refinery upgrade began in March 2019 and included a new resid hydrocracking unit planned for operation by 2023. Confirm the current project and commissioning status with Bapco.
Which hazardous areas are on Sitra?
Mainly the Bapco refinery and storage reservoirs, with process units, tank farms and loading facilities, plus the port. The extrusion and other light industry may have limited zones. Ask each operator for its classification drawing.
Does hydrogen service change what I should look for?
It can, because hydrogen units sit in the most demanding gas group, so the marking must cover that group. Sitra has hydrogen and hydrocracking units. Ask the operator for the classification of each unit and compare it with the device label rather than assuming one marking fits the whole refinery.
