CNRL: climate and equipment wear
Operations in northern Alberta and Saskatchewan sit in a continental climate, so cold-weather performance of batteries and screens matters; this is general regional knowledge rather than a company statement.

Explosion-Proof Mobile Phone Supplier for CNRL
Canadian Natural is headquartered in Calgary and operates mainly in British Columbia, Alberta, Saskatchewan and Manitoba, with offshore operations in the UK sector of the North Sea and off Cote d'Ivoire and Gabon. It operates the Horizon oil sands mining and upgrading project about 75 km north of Fort McMurray, Alberta, and the Athabasca Oil Sands Project acquired in 2017. This page sets out how an explosion proof mobile phone supply route to CNRL will work for the IS-04Z1, and what is and is not available before launch.

WhereCNRL
Short answer. An explosion proof mobile phone for CNRL 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

The organisation · CNRL
Working with Canadian Natural Resources Limited (CNRL): sites and classified areas
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
Sites and areas
- Horizon oil sands (north of Fort McMurray)
- Athabasca Oil Sands Project
- Alberta heavy oil and gas operations
Classified areas
- Oil sands mining and upgrading units
- Oil and gas production facilities
- Gas processing
Supplier approval · CNRL
Becoming an approved supplier to CNRL
CNRL uses ISNetworld (ISN) for health, safety and environment qualification; businesses register through the prospective suppliers page, and all contractors must ultimately qualify with ISN to work for CNRL. 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.

More about CNRL that matters for portable equipment
CNRL: industry on the ground
Canadian Natural is described as the largest producer of heavy crude oil in Canada and the largest independent natural gas producer in Western Canada, so both heavy-oil and gas sites are common.
CNRL: industry on the ground
In 2018 synthetic crude from northern Alberta oil sands mining made up 39% of production, natural gas 24%, light and medium crude and liquids 13%, and Pelican Lake heavy crude 6%.
CNRL: who works there
The company also owns and operates the Athabasca Oil Sands Project, about 70 km north of Fort McMurray, adding a second large mining and upgrading site in the Athabasca region.
The term · explosion proof
What “explosion proof” means for a smartphone
“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 CNRL. At oil sands mining and upgrading units, 'explosion-proof' in everyday speech covers several concepts. Flameproof Ex d enclosures protect fixed motors and switchgear, while intrinsic safety limits the energy of a handheld. A phone used on upgrader rounds relies on intrinsic safety, which is the route the IS-04Z1 is designed around.
The route · supply
Sourcing the IS-04Z1 for CNRL
Supply of the IS-04Z1 to CNRL 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 · CNRL
Frequently asked questions
Can CNRL 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 explosion proof mobile phone for CNRL 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
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.
How does CNRL approve suppliers?
CNRL uses ISNetworld (ISN) for health, safety and environment qualification; businesses register through the prospective suppliers page, and all contractors must ultimately qualify with ISN to work for CNRL.
How will SAMS supply CNRL?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
How cold do oil sands sites get and does it affect phone use?
Winters in northern Alberta can be severe, with long periods well below freezing, which reduces battery capacity and can affect screens and gloves-on use. Check the device's rated operating temperature and ask the site about its cold-weather work rules.
Are Horizon and the Athabasca project different sites for equipment approval?
They are separate large mining and upgrading operations with their own contractors, inductions and permit systems. A device approved at one site is not automatically accepted at another, so confirm each site's requirements with its safety and electrical teams.
Does Alberta winter cold matter for a handset at Horizon?
Yes. Low temperatures reduce battery capacity and make touchscreens harder to use with gloves. Check the device's stated operating temperature range against site conditions, and keep spares warm in a safe area. IP68 helps against snow melt and dust but is not explosion protection. Confirm with the operator.
