In industries such as oil and gas, chemical processing, logistics, and manufacturing, safety isn’t optional—it’s everything. One spark in the wrong environment can mean the difference between safe operations and catastrophic loss. That’s why devices and equipment used in these hazardous zones must comply with international safety standards like ATEX, IECEx, and other global certifications.

These certifications aren’t just paperwork or marketing claims. They are rigorous, internationally recognized systems that prove a device has been tested, validated, and approved for use in potentially explosive atmospheres.

In this article, we’ll simplify these complex standards—what ATEX and IECEx mean, how they differ, how they’re tested, and why they are essential for anyone working in hazardous environments. We’ll also highlight how brands like Conquest integrate these certifications into their rugged smartphone technology to deliver both safety and superior performance.

Understanding Hazardous Environments

Hazardous areas, sometimes called “Ex zones,” are classified spaces where flammable gases, vapors, or dust can mix with air, creating an explosive atmosphere.

Common examples include:

• Oil rigs and refineries

• Chemical processing plants

• Grain silos and flour mills

• Mining operations

• Fuel storage facilities

In such places, even a small electrical spark from a smartphone or handheld device could ignite an explosion. That’s why every device used there must be designed and certified to prevent ignition under any condition.

This is where ATEX and IECEx certifications come in—they guarantee that safety devices can operate in explosive atmospheres without causing ignition or malfunction.

What Is ATEX Certification?

ATEX stands for ATmosphères EXplosibles—a European Union directive that governs equipment used in explosive atmospheres. It ensures that all electronic devices, machinery, and protective systems meet strict safety standards to prevent ignition in hazardous environments.

ATEX certification gives organizations the confidence that every certified device—whether a smartphone, sensor, or control system—has been rigorously tested to perform safely where flammable gases, vapors, or dust are present.

The Two Main ATEX Directives:

1. ATEX 114 (2014/34/EU) – Applies to manufacturers, ensuring their equipment meets essential health, safety, and design requirements before being placed on the market. This directive focuses on the technical and manufacturing standards that guarantee explosion protection.

2. ATEX 153 (1999/92/EC) – Applies to employers and operators, defining clear responsibilities for maintaining worker safety in explosive environments. It covers equipment usage, installation, and risk management within the workplace.

Together, these directives form a comprehensive framework that covers both product design and operational safety, ensuring that certified equipment remains reliable throughout its service life.

Best Practices for Maintaining ATEX-Certified Equipment

Achieving ATEX certification is just the beginning—maintaining compliance is an ongoing process. To ensure continued safety and performance, organizations should follow the Best Practices for Maintaining ATEX-Certified Equipment, which include:

• Regular Inspections: Conduct periodic checks to ensure no damage, corrosion, or unauthorized modifications compromise the device’s explosion-proof integrity.

• Proper Cleaning Procedures: Use only approved, non-conductive cleaning agents and follow manufacturer guidelines to prevent static buildup or seal degradation.

• Qualified Personnel: Ensure only trained technicians handle repairs, replacements, or maintenance of ATEX-certified equipment.

• Environment Monitoring: Continuously monitor ambient temperature, pressure, and dust levels to keep devices operating within certified parameters.

• Documentation & Traceability: Maintain up-to-date maintenance logs, inspection records, and certification documents for audits or regulatory checks.

Implementing these best practices ensures that ATEX-certified devices continue to perform safely and effectively, extending their operational lifespan and keeping teams protected in high-risk zones.

What Is IECEx Certification?

While ATEX certification governs safety standards in Europe, IECEx offers a global approach. The International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx) provides a unified framework ensuring that electrical and electronic devices are safe for use in hazardous areas anywhere in the world.

IECEx certification confirms that a product meets internationally recognized safety standards, reducing the need for multiple national tests and simplifying global trade. It’s widely adopted across Asia, Australia, Africa, and the Middle East, offering manufacturers and operators a single standard of trust.

The IECEx Certification Process

The IECEx approval process is known for its transparency and rigor. It includes:

1. Product Testing and Evaluation – Conducted by accredited IECEx laboratories to verify explosion protection measures.

2. Quality Assessment – Ensures that the manufacturer’s production systems maintain consistent compliance and traceability.

3. Ongoing Surveillance – Regular factory inspections and audits verify that standards are upheld over time.

All valid certificates are publicly listed in the IECEx online database, allowing customers, inspectors, and end users to verify authenticity instantly.

5 Common Mistakes to Avoid with IECEx-Approved Devices

Even with certification in place, many organizations inadvertently compromise safety and performance. Here are the 5 Common Mistakes to Avoid with IECEx-Approved Devices:

1. Ignoring Environmental Limits – Using devices outside their certified temperature or pressure range can void the certification and pose explosion risks.

2. Unauthorized Modifications – Adding attachments, drilling, or altering enclosures without manufacturer approval can compromise explosion protection integrity.

3. Improper Maintenance – Using non-qualified personnel or uncertified spare parts may lead to non-compliance and safety failures.

4. Neglecting Regular Inspections – Skipping periodic checks can allow small defects—like worn seals or loose fittings—to escalate into serious hazards.

5. Assuming Global Interchangeability – While IECEx has wide acceptance, local authorities may still require region-specific documentation or markings.

Avoiding these mistakes is essential for ensuring that IECEx-certified devices continue to deliver the protection and reliability they were designed for. A strong maintenance culture and adherence to manufacturer guidelines keep your equipment compliant and your workforce safe.
