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Most gasifiers at Sasolburg have been replaced by autothermal reformers fed with natural gas piped from Mozambique, which shifts feedstock handling from coal to gas pipelines and process gas.

WhereSasol
Short answer. An intrinsically safe mobile phone for Sasol 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

Supplier approval · Sasol
Supplier registration at 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: industry on the ground
The Sasol 1 site began commissioning in 1954, Sasol 2 was completed in 1980 and Sasol 3 came on stream in 1982, so the Secunda and Sasolburg complexes combine plant of very different ages.
Sasol: who works there
Sasol Mining operates six coal mines that supply the Secunda synfuels and Sasolburg complexes, so underground coal-mine conditions sit next to chemical plant conditions inside one company.
Sasol: people and language
Sasol employs over 27,000 people and has operations in 33 countries, and it was a founding member of the Fuels Industry Association of South Africa when that body launched in 1994.
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 Sasol. Rounds across synthetic fuels, chemical plants, gas processing and the Natref refinery involve extensive walking and many instrument checks. A handheld designed for intrinsic safety could capture readings, photos and calls in classified spots if its certificate allows. Permit rules are for Sasol to set, including at the Mozambique gas operations.
The route · supply
Sourcing the IS-04Z1 for Sasol
Supply of the IS-04Z1 to Sasol starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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 intrinsically safe 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.
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.
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.
How will SAMS supply Sasol?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do Sasol's mines and plants use the same hazardous-area rules?
Not necessarily. Underground coal mines in South Africa fall under mining safety legislation with its own approval routes, while chemical plants work to industrial classified-area practice. Confirm with Sasol Mining and with each plant which approvals and certificates it expects for portable equipment.
How does the Highveld climate affect phones used at Secunda or Sasolburg?
Both sites are on South Africa's inland Highveld, where days can be warm and winter nights cold with frost, and dust is common near mines and stockpiles. Check the device's operating temperature range, dust ingress rating and battery behaviour in cold, and ask the site about its limits.
Does the phone work in Highveld winters?
The IS-04Z1 has IP68 protection and a 4,000 mAh battery, but cold-weather battery behaviour and the permitted temperature range will come from the final certificate and datasheet. Check them for Highveld winters. IP68 is not explosion protection, and certification is still in progress.
