What Is IECEx Certification?
IECEx Certification is designed for professionals working in hazardous areas, such as oil & gas, petrochemical, or chemical plants. It demonstrates that you have the knowledge, skills, and competence to perform your job safely and effectively.
For example:
- An engineer maintaining electrical equipment in a chemical plant must identify safe zones, choose the right tools, and follow IEC safety standards.
- A technician installing equipment in a refinery must understand explosive atmosphere risks and apply safety procedures.
By earning IECEx Certification, you gain:
- Confidence to perform your role safely
- Global recognition for your competence
- Career advancement opportunities in the hazardous area industry
How Does the IECEx CoPC Assessment Work?
The IECEx CoPC assessment evaluates your theoretical knowledge and practical skills. Here’s how it works, step by step:
- Select Modules – Only study modules relevant to your job role (Ex001–Ex010).
- Join Training Program – Attend a structured training program like Extrainings, covering both theory and practical skills.
- Apply for Assessment – Submit your application and documents to an IECEx-approved certification body.
- Complete Theory + Practical Evaluation – Take tests that examine your knowledge and hands-on competence.
- Receive CoPC Certificate – Once you pass both parts, your certificate is issued, recognized globally.

Frequently Asked Questions (FAQs)
IECEx stands for the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. It is a globally recognized certification system that ensures equipment and personnel meet stringent safety standards for working in hazardous environments where explosive atmospheres may be present. The Certificate of Personnel Competence (CoPC) confirms that an engineer or technician has the skills and knowledge to work safely in hazardous areas.
The certificate is issued by an IECEx-approved Certification Body (ExCB) — such as Karandikar Laboratories Pvt. Ltd. (India) or Ex Certification & Inspection Services LLC (UAE). Extrainings provide training and preparation — not the certification itself.
- Training: Helps you learn, practice, and prepare for the assessment. (That’s what Extrainings offers.)
- Certification: Is the official approval issued after you pass the IECEx assessment, conducted by an authorized body.
The IECEx CoPC has no fixed expiry, but you must maintain competence through ongoing work and refreshers. Employers often request proof of updated knowledge every 3–5 years.
