Explosion-Proof Mobile Phone for Sonangol
Sonangol is Angola's state-owned oil and gas company, headquartered in Luanda. A 200,000 barrel-a-day refinery at Lobito, with Sonangol planned to hold 70%, has been proposed but much delayed, so check current project status before assuming new refinery work. This page explains what to look for in an explosion proof mobile phone for Sonangol, and where the IS-04Z1 stands against that list today.

Supplier approval · Sonangol
Becoming an approved supplier to Sonangol
Sonangol runs a Supplier Portal (Portal de Fornecedores) for registration, pre-qualification and qualification; pre-registration is completed through the suppliers section of its website and is free. 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.

More about Sonangol that matters for portable equipment
Sonangol: who works there
Sonangol P and P, founded in 1992, is the group's prospecting and production subsidiary, and in December 2013 the group acquired exploration rights to five onshore oil blocks.
Sonangol: who works there
The group created subsidiaries for services it needed, including telecommunications, trucking, shipping, data management, engineering and seismic work, so many site contractors are Sonangol affiliates.
Sonangol: logistics and access
Economic growth in 2025 was reported to have eased partly because of scheduled inspections and maintenance shutdowns in the oil sector, showing that planned shutdown periods affect activity.
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 Sonangol. On offshore platforms and at the Luanda refinery, people often say 'explosion-proof' for any approved gear. In practice, flameproof Ex d enclosures protect fixed equipment, while intrinsic safety limits the energy of a portable device. For a handheld phone used on a platform deck or in refinery process units, intrinsic safety is the concept the IS-04Z1 is designed around.

- 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

Questions · Sonangol
Frequently asked questions
Can Sonangol buy the IS-04Z1 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 mobile phone for Sonangol 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.
How does Sonangol approve suppliers?
Sonangol runs a Supplier Portal (Portal de Fornecedores) for registration, pre-qualification and qualification; pre-registration is completed through the suppliers section of its website and is free.
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 Sonangol the operator at Angola's offshore fields?
Usually not directly. Sonangol acts as concessionaire and partner, while international oil companies commonly operate the offshore blocks. Equipment standards and approved-vendor processes therefore depend on the operator of the specific field. Identify the operator and ask for its contractor and equipment requirements.
What language should documentation be in for Angola?
Portuguese is the official language, so manuals, labels and training for hazardous-area devices are often expected in Portuguese, while international operators commonly work in English. Confirm with the operator and Sonangol which language is required for approval and for site induction.
Can a phone be supplied to Sonangol sites directly?
Not at present. Sonangol uses a Supplier Portal for registration and qualification, and SAMS expects supply after certification to come through authorised distributors. SAMS can currently share a datasheet and schedule. Check the portal's current requirements before assuming any route is open.
