The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Sitra, Bahrain. Around Sitra, loose talk of explosion-proof covers very different things. Hydrocracking and hydrogen units, crude and product storage and sulphur recovery each need the right protection concept. Flameproof Ex d suits fixed equipment; intrinsic safety suits portable devices. The IS-04Z1 follows intrinsic safety, with certification still pending.

Specifying an explosion proof 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 explosion proof smartphone in Sitra 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 explosion proof smartphone in Sitra 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
