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.
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. This page sets out how an explosion proof smartphone supply route to South Africa will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An explosion proof smartphone for South Africa cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | South Africa: Durban, Richards Bay, Secunda, Mpumalanga | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in South Africa. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS South Africa market guide.
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.
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.
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.
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.
“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.
Nothing can be bought for South Africa today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
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.
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.
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.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Underground mines typically use Group I classification, with methane and coal-dust risks, while surface plants use Group II and III. SANS standards such as SANS 1515 cover mine gas-measuring equipment. Ask the mine or plant engineer which group and protection level the area drawing specifies before ordering.
Yes. The National Code of Practice for Electrical Machinery in Hazardous Locations sits under the Occupational Health and Safety Act 1993 and refers to SANS standards. Mines also have their own regulations and standards, so confirm which rules apply with the site's engineering and compliance team.
No. Underground mining is equipment Group I, which is outside the scope of this device. The IS-04Z1 targets surface areas such as coal handling plants and process units using Zone 1 and Zone 21. Confirm the area and equipment group with the mine's safety officer.
