Cold winters
Edmonton winters are cold enough that battery performance and glove use are practical considerations for outdoor work.
Air quality across the Industrial Heartland is monitored by the not-for-profit Fort Air Partnership, formed in 1997, an indication of the continuous monitoring regime that operates around the plants. Crude processing units, tank farms and loading areas contain classified areas where Zone 1 and Zone 2 equipment is required. This page explains what to look for in an Ex-proof smartphone for Edmonton refineries (Refinery Row), and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Edmonton refineries (Refinery Row): pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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 |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| Where it applies | Edmonton refineries (Refinery Row): Refinery process units, Crude and product tank farms, Loading racks | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Edmonton Refinery. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
Edmonton winters are cold enough that battery performance and glove use are practical considerations for outdoor work.
Imperial's Strathcona Refinery opened in 1975, employs about 450 people and is reported at roughly 187,000 barrels per day.
Of the four upgraders that process mined bitumen, Scotford is the only one not integrated with a mine bitumen plant, so it relies on feedstock supplied from elsewhere.
Sturgeon Refinery, originally designed as a bitumen upgrader, also processes in-situ production from Cold Lake, linking the Edmonton area to heavy-oil supply.
Refinery Row, a concentration of refineries in west Sherwood Park just east of Edmonton, includes the Strathcona Refinery (Imperial Oil) and the Suncor Edmonton Refinery.
Alberta's Industrial Heartland covers 533 km2 across Fort Saskatchewan, Lamont, Strathcona and Sturgeon counties, plus the 49 km2 Edmonton Energy and Technology Park, for a total of 582 km2 east of Edmonton.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Edmonton refineries (Refinery Row). Refinery process units and loading racks commonly involve hydrocarbon gases and vapours, so the marking check would compare gas group and temperature class with the operator's area data. The IS-04Z1 targets II 2 G Ex ib IIC T4, which covers a wide range of gases, but the operator makes the final fit decision.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Likely candidates are refinery process units, crude and product tank farms, loading racks, wastewater treatment. 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.
It is a 582 km2 cluster of refineries, upgraders and chemical plants east of Edmonton across several counties. Because many operators share the area, contractor induction and device rules differ by plant. Confirm site requirements before mobilising.
Typically the operator checks Ex certification marking, gas group and temperature class against the area classification, and may require Canadian recognition of the certificate. Confirm accepted schemes and approvals with the site's electrical authority.
It can be planned for, but turnaround work is run under the operator's permit system, which still controls hot work and entry. An intrinsically safe handheld may support inspection records and photos in classified areas once certified. Confirm with the operator which areas, zones and gas groups apply to each task.
