Dispersed sites
The play extends through areas around Fort St. John and Dawson Creek in British Columbia and into Alberta, so facilities are spread over a wide area.
The Montney Formation covers about 130,000 square kilometres of British Columbia and Alberta and is a major shale gas and tight oil resource. Wellpads, compressor stations and gas plants across it contain classified areas. If you are specifying an ATEX and IECEx mobile phone for Montney gas play, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Montney gas play: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Montney Gas Field. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The play extends through areas around Fort St. John and Dawson Creek in British Columbia and into Alberta, so facilities are spread over a wide area.
ARC Resources has described Attachie near Fort St. John producing more than 30,000 barrels of oil equivalent per day, including condensate.
A 2013 joint study by the National Energy Board, the BC Oil and Gas Commission and the Alberta Energy Regulator assessed the formation, and gas is produced in both provinces, so operators work under two regimes.
In northeast British Columbia some wells contain hydrogen sulphide, which makes gas sour, flammable and potentially deadly if inhaled, and Geoscience BC research maps where it occurs in unconventional reservoirs.
The Montney is a Lower Triassic unit of dolomitic siltstone and sandstone up to about 280 m thick, which supports long horizontal wells.
The Montney Formation was first described in 1962 from Texaco's Buick Creek No. 7 well, drilled 41 km north of Fort St. John immediately east of the Alaska Highway.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Montney gas play. A reviewer for a Montney producer, such as ARC Resources or Progress Energy Canada, would expect certificate evidence suited to wellpads, compressor stations and gas plants. A dual ATEX and IECEx route helps international partners in the ownership chain. The IS-04Z1 is in certification and no certificate has been issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are wellpads and wellheads, gas processing plants, compressor stations, condensate handling. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Hydrogen sulphide is a toxic hazard rather than an Ex rating, but sour sites add gas detection, breathing apparatus and rules for devices. Confirm requirements with the operator's induction team and ensure your device meets zone and gas group needs.
Typically wellpads, gas gathering, compressor stations and gas plants with flammable natural gas, and some sites with condensate or sour gas. Classified areas vary by facility, so request the operator's classification drawing before bringing equipment.
Yes, gas from the Montney supplies LNG Canada through the Coastal GasLink pipeline. That link does not change the area classification at a wellpad, which the producing operator decides. A handset would still need to match the zone, gas group and temperature class assigned for that location. Ask the operator for the area data.
