Sasol: who works there
The group is organised into two upstream business units, three regional operating hubs and several market-facing strategic business units, so site procurement usually follows the relevant hub or unit.

Supplier approval · Sasol
How suppliers reach Sasol
Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba for suppliers working with it in South Africa and Mozambique; confirm current requirements with Sasol Supplier Management. 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.
Field notes · Sasol
More about Sasol that matters for portable equipment
Sasol: background
Sasol was formed in 1950 at Sasolburg around coal liquefaction, and today it develops synthetic fuel technologies and produces liquid fuels, chemicals, coal tar and electricity.
Sasol: industry on the ground
Beyond fuels, Sasol sells over 200 chemical products worldwide, including ammonia-based fertilizers and explosives, which adds dust, ammonia and solvent hazards to the plant mix.
Sasol: infrastructure
Most gasifiers at Sasolburg have been replaced by autothermal reformers fed with natural gas piped from Mozambique, which shifts feedstock handling from coal to gas pipelines and process gas.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Sasol. Large South African complexes such as Secunda draw in international EPCs and specialist shutdown contractors, many of whom know the IECEx scheme. A reviewer should read the certificate of conformity together with its schedule of conditions. The IS-04Z1 is designed for IECEx and certification is in progress.

Questions · Sasol
Frequently asked questions
Can Sasol buy the IS-04Z1 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 IECEx mobile phone for Sasol 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
How does Sasol approve suppliers?
Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba for suppliers working with it in South Africa and Mozambique; confirm current requirements with Sasol Supplier Management.
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 Sasol a good target for a new supplier of Ex-rated devices?
Sasol is a large multi-site buyer, but supplier approval is run by the company and its units. Typically a new supplier needs to register, pass technical and HSE review and often start with a pilot. Confirm the current route with Sasol's procurement and the relevant site engineering group.
Which Sasol areas are most likely to need intrinsically safe handhelds?
Typical candidates are gas and liquid process units, tank farms and loading areas at Secunda and Sasolburg, plus underground coal mines where methane and coal dust create their own classification rules. Zoning is decided per installation, so ask each site's HSE team for classification drawings.
How do suppliers apply to work with Sasol?
The sheet says Sasol runs supplier applications through the Supplier Information Management (SIM) module on Ariba, for suppliers working with it in South Africa and Mozambique. Confirm current requirements with Sasol Supplier Management. The IS-04Z1 is pre-launch and has no certificate.
