Safety is the cornerstone of operations in hazardous environments. Whether you’re operating in an offshore rig, a chemical processing plant, or a grain storage facility, explosive atmospheres demand strict controls—especially when it comes to using electronic devices. One of the highest global standards in this space is the IECEx intrinsically safe certification.
This post explores what it means for a device to be IECEx certified, how it differs from ATEX, what makes a device intrinsically safe, and which certified devices are best suited for use in high-risk environments. We also answer common questions and recommend top products from Intrinsically Safe Store.

What Is IECEx Certification?
IECEx stands for the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. It’s an international system that verifies whether electrical and electronic equipment is safe to operate in hazardous locations where flammable gases, vapors, or dust may be present.
IECEx Covers Three Core Areas:
Equipment Certification (IECEx Certified Equipment Scheme): Devices are tested against IEC standards to ensure they will not ignite an explosive atmosphere.
Service Facility Certification: Verifies that maintenance and repair facilities meet safety requirements for certified equipment.
Personnel Certification (CoPC): Certifies the competency of workers performing tasks in hazardous environments.
IECEx certification is globally recognized, providing consistency and clarity in environments where equipment failure could result in severe accidents.

What Makes a Device Intrinsically Safe?
An intrinsically safe (IS) device is engineered to operate with electrical energy levels that are too low to ignite a hazardous atmosphere, even under fault conditions. This design approach is particularly suitable for portable electronics used in explosive zones.
Key Intrinsic Safety Principles
Energy Limitation: Circuits are designed to restrict energy so that it remains below ignition thresholds.
Temperature Control: Devices are engineered to remain cool enough to prevent hot surfaces from becoming ignition sources.
Fail-Safe Design: Intrinsically safe equipment must be safe even if two simultaneous faults occur.
Devices marked with “Ex i” are typically suitable for Zone 0, Zone 1, or Zone 2—depending on the level of hazard and likelihood of exposure.
IECEx vs ATEX: What’s the Difference?
While both IECEx and ATEX focus on explosion protection, they are governed by different systems and serve different markets.
| Feature | IECEx | ATEX |
|---|---|---|
| Geographic Scope | Global | European Union |
| Basis | IEC International Standards | EU Directives (94/9/EC) |
| Use of Test Reports | Yes (QARs, CoCs) | Limited (manufacturer’s declaration) |
| Self-Certification | No | Possible for low-risk devices |
| Documentation Transparency | High | Lower than IECEx |
If your operations are global, IECEx is often the better choice due to its international recognition and standardization.

Why Use IECEx Intrinsically Safe Devices?
Choosing IECEx intrinsically safe devices ensures both worker safety and compliance with global regulations. Here’s why it matters:
1. International Acceptance
With IECEx certification, you can confidently deploy the same devices across regions—eliminating the need for multiple local certifications.
2. Improved Operational Safety
Certified devices reduce the risk of explosions by eliminating ignition sources, ensuring safer workspaces in explosive zones.
3. Efficient Field Operations
IECEx-certified mobile devices allow teams to use digital tools—such as inspections, asset tracking, or video calls—even in Zone 1 areas.
4. Regulatory & Stakeholder Assurance
IECEx devices demonstrate proactive safety measures and simplify audits or inspections by third-party regulators.

Frequently Asked Questions (FAQs)
What does IECEx intrinsically safe mean?
It means the device is certified under the IECEx scheme to be safe for use in explosive environments. The device is designed not to ignite gases, vapors, or dust under normal or fault conditions.
Can I use IECEx certified devices worldwide?
Yes, IECEx is internationally accepted and ideal for multinational operations. However, local regulations should always be verified.
What zone classifications does IECEx use?
Zones range from 0 to 2 for gases and 20 to 22 for dusts. Zone 0 is the most hazardous and requires the highest level of protection.
Do IECEx and ATEX certifications overlap?
They both address explosive atmospheres but originate from different systems. A device can be certified under both IECEx and ATEX, but the certifications are distinct.
Where can I buy IECEx certified intrinsically safe devices?
Visit Intrinsically Safe Store to view a wide selection of IECEx certified smartphones, tablets, and wearables.
