South Africa: industry on the ground
Secunda CTL, owned by Sasol, is the world's largest coal liquefaction plant, with capacity of 160,000 barrels a day from units built in 1980 and 1984, so synthetic fuel gas and liquids handling is extensive.

Explosion-Proof Cell Phone Distributor in South Africa
A Zone 1 / Zone 21 smartphone for crews at the Secunda and Sasolburg complexes, the Natref and Cape Town refineries, Mossel Bay, the fuel terminals and the surface plants of South African mining. Electrical safety for some products is handled through SABS certificates of conformity and an NRCS letter of authority, which are separate from ICASA's radio approval. An explosion proof cell phone distributor in South Africa would carry the IS-04Z1 to these buyers once certification completes.

Short answer. South Africa has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · South Africa
More about South Africa that matters for portable equipment
South Africa: geography and layout
Mining areas range from the Witwatersrand gold fields to Limpopo platinum mines such as Two Rivers at Steelpoort, so remote sites and deep underground workings are both common.
South Africa: background
The 1886 discovery on the Witwatersrand started the gold rush that built Johannesburg's mining industry, and the country is still fifth in world gold production by one account.
South Africa: industry on the ground
South Africa is the world's largest producer of chrome, manganese, platinum and vanadium and the third-largest coal exporter, so mining is a major source of hazardous-area work.
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 South Africa. Explosion-proof is the common search phrase, but Secunda and Sasolburg combine hydrogen-rich streams with large fixed plant. Flameproof Ex d suits heavy enclosures, while the IS-04Z1 uses intrinsic safety to limit the energy of a handheld. The difference matters when a reviewer asks which protection concept applies to the device carried through a gate.
The route · distribution
Distributing the IS-04Z1 in South Africa
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for South Africa. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in South Africa.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · South Africa
Frequently asked questions
Can we buy an explosion proof cell phone in South Africa 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 explosion proof cell phone in South Africa cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated 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 sites in South Africa does this cover?
The market guide for South Africa covers Secunda, Mpumalanga, Sasolburg, Free State, Milnerton, Cape Town, Mossel Bay, Western Cape, among others. Site-level pages are linked below.
How do I become a SAMS distributor for South Africa?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for South Africa.
Which South African authority approves radios and phones?
ICASA sets radio type approval, and it is described as relying on EU test reports covering spectrum use, EMC and electrical safety, with a conformity label on the equipment and packaging. SABS and NRCS handle some electrical-safety certificates separately. Confirm the route for your device with ICASA or an agent.
What conditions affect devices at South African mines and plants?
Conditions vary from hot, dusty surface sites to deep underground workings with heat and humidity. Check ingress protection, operating temperature range and battery life, and confirm site rules on device approval and gas detection with the mine or plant operator.
How would the handset cope with highveld temperature swings?
IP68 sealing and a rugged build are aimed at hot summers, cold winter mornings and dusty conditions. The approved ambient range will be stated on the certificate, which is in progress. Check that range against the coldest morning shift at your site before ordering.
