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.
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. Its main South African complexes are at Secunda and Sasolburg, and it also has gas operations in Mozambique. This page sets out how an explosion proof mobile phone supply route to Sasol 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 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. 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 | Sasol: Gas processing, Coal mining operations, Synthetic fuels and chemical plants | 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.
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
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.
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 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 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.
Sasol mines more than 40 million tonnes of saleable coal a year, mostly as gasification feedstock for Secunda, and its Secunda collieries are described as the world's largest underground coal operation.
“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 Sasol. Synthetic fuels, chemical plants and refinery units show that explosion-proof is shorthand for several concepts. Flameproof Ex d covers fixed motors and enclosures, and intrinsic safety suits handhelds. A phone relies on the second. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, subject to certification.
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.

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.

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.
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.
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.
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.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
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.
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.
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.
