Intrinsically Safe Mobile Phone for PDO
Petroleum Development Oman (PDO) is Oman's main oil and gas producer, operating a concession of about 90,000 square kilometres. The Government of Oman holds 60 per cent, Shell 34, TotalEnergies 4 and Partex 2. This page explains what to look for in an intrinsically safe mobile phone for PDO, and where the IS-04Z1 stands against that list today.

WherePDO
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for PDO: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Supplier approval · PDO
Supplier registration at PDO
Joint Supplier Registration System (JSRS) certification from the Ministry of Energy and Minerals is a prerequisite before suppliers can be qualified by PDO; PDO's website has a Vendor Corner for registration. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
Field notes · PDO
More about PDO that matters for portable equipment
PDO: infrastructure
A 276 kilometre pipeline from the interior fields to the coast was laid in the 1960s, ending at an industrial complex, tank farm and marine terminal at Mina al Fahal near Muscat.
PDO: rules and approvals
PDO's headquarters are at Mina Al Fahal in Muscat, and supplier guides say firms generally cannot bid on PDO tenders without prior vendor registration and approval.
PDO: background
PDO's name was shortened to Petroleum Development (Oman) in 1951 after the Dhofar concession lapsed, and the company later operated as Petroleum Development Oman from 1967.
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 PDO. Operators here walk wellheads, gathering stations and gas plants on inspection rounds, often with long drives between them. A handheld designed for intrinsic safety lets an operator photograph a gauge, log a reading or call the control room without a hot-work or gas-free permit for the device itself. Permit rules still belong to PDO.

Specifying an intrinsically safe mobile phone for PDO
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 · PDO
Frequently asked questions
Can PDO buy the IS-04Z1 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 intrinsically safe mobile phone for PDO 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 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.
How does PDO approve suppliers?
Joint Supplier Registration System (JSRS) certification from the Ministry of Energy and Minerals is a prerequisite before suppliers can be qualified by PDO; PDO's website has a Vendor Corner for registration.
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.
Where does PDO work involve Zone 1 areas?
Typically at wellsites, production stations and gas processing plants in the interior concession area, and at the Mina al Fahal coastal terminal and tank farm. The operator issues the hazardous-area classification for each facility, so ask for the zone, gas group and temperature class before selecting equipment.
Is PDO the only major operator in Oman?
PDO is the largest onshore exploration and production company and delivers most of Oman's crude oil and gas supply, but other operators and OQ's refining and petrochemical businesses also run hazardous-area sites. Each organisation sets its own supplier and equipment rules, so confirm with the one that controls your site.
How would the phone cope with desert heat on remote concession sites?
The IS-04Z1 is IP68 rated against dust and water and carries a 4,000 mAh battery, but ambient temperature limits will come from the final certificate and datasheet. Do not assume operation beyond the stated temperature range. IP68 is not explosion protection. Check the temperature class against the area before use.
