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.

More about South Africa that matters for portable equipment
South Africa: rules and approvals
The code references a family of SANS standards, including SANS 10086 on installation, inspection and maintenance of equipment in explosive atmospheres, SANS 1489 on connectors and SANS 1515 on gas measuring equipment for mines.
South Africa: rules and approvals
ICASA, based in Centurion, sets radio type approval, relying on EU test reports for spectrum, EMC and electrical safety, and a conformity label must be affixed to the equipment and the packaging.
South Africa: rules and approvals
South Africa has a National Code of Practice for Electrical Machinery in Hazardous Locations under the Occupational Health and Safety Act 1993, with a section on regulatory requirements for explosion-protected apparatus.
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 South Africa. Intrinsic safety suits long inspection routes across very large sites such as Secunda and the Mpumalanga coalfields, where process plant and conveyor routes offer no safe-area socket mid-shift. A handheld that limits ignition energy allows camera, torch and GNSS use on the round without leaving the area.

Specifying an intrinsically safe 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 intrinsically safe 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 intrinsically safe mobile 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.
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.
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.
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.
