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.

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: rules and approvals
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.
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.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In South Africa. Large South African fleets cover operators such as Eskom and Transnet alongside mining and chemical contractors. EMM and MDM support lets IT control a large fleet from one console, and coverage across very large sites is part of the planning. Charging takes place in safe areas, with the battery meant to last a shift.

Specifying an industrial mobile phone for South Africa
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 · South Africa
Frequently asked questions
Can we buy an industrial mobile phone in South Africa 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 industrial mobile phone in South Africa cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and 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.
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.
Do mines in South Africa have different requirements from process plants?
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.
Is there a national code for hazardous locations in South Africa?
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.
Can the IS-04Z1 be used underground in a South African mine?
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.
