Dense cluster
The industry occupies a compact area near the St. Clair River, so contractors move between neighbouring sites.
Sarnia, Ontario, is home to Chemical Valley, a cluster of refineries and petrochemical plants that Wikipedia puts at around 60 facilities. Imperial Oil, Suncor and Shell run refineries, alongside chemical producers, so process and storage areas are classified. An IECEx smartphone distributor in Sarnia (Chemical Valley) would carry the IS-04Z1 to these buyers once certification completes.

IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Sarnia (Chemical Valley). Chemical Valley includes Shell Canada and other companies with international parents, and contractors move between neighbouring plants.

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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Likely candidates are refinery process units, petrochemical plants, product storage and loading, pipeline terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.

It is the cluster of refineries and chemical plants south of downtown Sarnia. Typical hazards include flammable liquids, gases and some toxic substances, so classified areas and gas detection are common. Confirm each plant's zone drawings before bringing devices.
Usually only in permitted non-classified areas or with certified devices in classified ones, and plants set their own rules at induction. Confirm requirements with the specific operator.
Wikipedia puts the cluster at around 60 facilities, including refineries and petrochemical plants near the St. Clair River. Large pipelines bring Alberta crude oil to Sarnia. The mix of owners means area classification and procurement differ between sites, so ask each operator for its own data.
