Hazardous Environments? Meet the i.safe Mobile IS945.1 (C1/D1 Intrinsically Safe Windows Tablet)
The Only Class I, Division 1 Windows Tablet Currently on the Market: The i.safe MOBILE IS945.1
Hazardous area computing has always forced a trade-off. You could get a rugged tablet, or you could get a fully capable Windows operating system — rarely both, and almost never with the certifications to legally operate in a Class I, Division 1 environment. That trade-off just got a lot smaller.
The i.safe MOBILE IS945.1 is currently the only intrinsically safe tablet on the market certified for Class I, Division 1 hazardous locations that also runs full Windows. For IT and operations leaders managing plants, terminals, or facilities where flammable gases, vapors, or combustible dust are a daily reality, that combination changes what’s possible for explosion proof mobile computing at the point of work.
Why CI/D1 Hazardous Environments Certification Matters — and Why It’s Hard to Find
Class I, Division 1 (C1/D1) is the North American classification for locations where ignitable concentrations of flammable gases or vapors can exist under normal operating conditions — not just during a leak or malfunction. It’s the strictest tier of hazardous location rating that mobile computing devices are commonly certified for, and it’s the standard that matters most in industries like oil and gas, chemical and petrochemical processing, pharmaceutical manufacturing, and grain handling.
Getting devices certified as Zone 1 tablets isn’t a matter of adding a rugged case to existing tablets. Intrinsic safety has to be engineered into the device from the circuit level up, limiting electrical and thermal energy so the device simply cannot generate a spark or surface temperature capable of igniting a hazardous atmosphere. That’s a fundamentally different design problem than drop-resistance or water resistance, and it’s why the field of true C1/D1-rated ATEX tablets is so narrow. Most vendors offer Zone 1/21 (the IECEx/ATEX equivalent used outside North America) or step down to a C1/D2 rating, which covers locations where hazardous atmospheres are only present under abnormal conditions. The IS945.1 carries IECEx, ATEX, and CSA/UL certification, meaning it’s approved for Zone 1/21 and Class I, Division 1 use — global coverage in a single device.
What’s Inside the i.safe Mobile IS945.1 Intrinsically Safe Tablet
Beyond the certification, the IS945.1 is built to hold its own as a full-featured field computer for mobile worker safety and operational efficiency:
Windows 11 IoT Enterprise — full desktop OS compatibility with your existing WMS, MES, historian, or maintenance software, no app rewrites required
Qualcomm QCM6490 octa-core processor with 8GB RAM and 128GB internal storage, expandable via microSD — enough headroom for demanding industrial applications and long-term OS support
10.1″ WUXGA display (1200 x 1920) with Corning Gorilla Glass and glove-enabled touch, built for outdoor visibility and use with PPE
4G/5G, Wi-Fi 6, Bluetooth 5.2, NFC, and multi-constellation GNSS (GPS, A-GPS, GLONASS, BeiDou, Galileo) for reliable connectivity and location tracking across campus networks or cellular
12MP rear / 5MP front cameras for inspection documentation, asset tagging, and remote video support
8160mAh user-replaceable battery for shift-length runtime without downtime for charging
IP68 and MIL-STD-810H rated, operating from -20°C to +55°C — built for the same conditions the hazardous area itself throws at it
Programmable red key for lone worker protection and SOS alerting, plus additional programmable side buttons
VESA 100 mounting and an optional docking/connectivity system for fixed-station or mobile operator panel deployments
Don’t need cellular? We also offer the IS945.2, which is a Wi-Fi-only version of this rugged tablet.
Where It Fits
IS945.1 intrinsically safe tablets are purpose-built for workers who need computing power inside classified areas: process operators doing rounds, maintenance technicians pulling up equipment manuals and work orders, EHS staff performing inspections, and control room personnel who need a mobile extension of the same systems they run from the desk. Because it runs Windows rather than a mobile OS, it also plugs into existing automation and IIoT software stacks with far less integration work than an Android-based alternative — a meaningful consideration for IT teams already managing a Windows-centric environment.
The optional Mobile Operator Panel configuration, which pairs the IS945.1 with a dedicated docking and interface system, extends this further — turning the tablet into a continuously powered, always-ready HMI for process automation tasks without pulling it out of the hazardous area for charging.
Deploying intrinsically safe tablets isn’t just a purchasing decision — it’s a compliance decision for hazardous environments. Zone and division ratings, area classifications, and permissible equipment groups all have to line up correctly, and getting it wrong carries real safety and regulatory consequences. This is exactly the kind of deployment where working with a specialist VAR pays off: matching the right certified explosion proof tablet to your facility’s actual area classification, coordinating with your EHS and process safety teams, and handling provisioning, MDM enrollment, and lifecycle support so IT isn’t learning hazardous location compliance on the fly.
CSSI has helped organizations across manufacturing, distribution, and process industries deploy rugged and intrinsically safe computing solutions that hold up to both the environment and the compliance requirements that come with it. The IS945.1 is currently the only C1/D1-rated Windows tablet available, making it a strong fit for teams that need Windows-native functionality in the most tightly regulated hazardous areas.
