Intrinsically Safe Mobile Phone for CNRL
CNRL is a Calgary-based oil and gas producer, founded in 1973, and is Canada's largest heavy crude oil producer. 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 explains what to look for in an intrinsically safe mobile phone for CNRL, and where the IS-04Z1 stands against that list today.

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.

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 CNRL. Upgrader rounds, shutdown inspections and field checks at Alberta production sites involve photographing equipment, reading tags and recording faults in classified areas. A handheld designed as intrinsically safe could carry that on one device. The IS-04Z1 is designed for this use, though certification is still in progress.

Specifying an intrinsically safe mobile phone for CNRL
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 · CNRL
Frequently asked questions
Can CNRL buy the IS-04Z1 today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an intrinsically safe 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.
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 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.
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 standard applies to hazardous-area phones at Canadian oil sands sites?
Canada uses its own classification and approval system, typically Class, Division or Zone markings accepted through Canadian certification bodies, rather than ATEX alone. Confirm with Canadian Natural and its site electrical authority which certification marks they accept for portable devices before supply.
Where would handheld devices be used on an oil sands upgrader?
Typical Zone 1 or Zone 2 or Division 1 or 2 locations include upgrader process units, hydrocarbon storage, loading areas and pipeline stations, while mine and camp areas are usually non-classified. Zoning is site-specific, so request the area classification drawings from the operator.
How does a business qualify to work for CNRL?
CNRL uses ISNetworld 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. Confirm current steps with CNRL. The IS-04Z1 has no certificate yet, so any evaluation unit needs site approval first.
