Getting your IECEx certification as a maintenance engineer isn’t just about adding another credential to your resume—it fundamentally changes what you’re allowed to do, what you’re expected to know, and how much you can earn. After training hundreds of maintenance professionals across the Gulf region, I’ve seen firsthand how this certification transforms careers, opens doors to senior positions, and significantly boosts earning potential.
If you’re considering IECEx certification or recently completed your training, understanding what actually changes in your day-to-day work helps you maximize the value of your investment. Let’s break down the practical impacts on your responsibilities, career trajectory, and compensation.
Typical Maintenance Tasks in Ex Areas
Before IECEx certification, many maintenance engineers perform routine work under supervision or follow prescriptive checklists without fully understanding the underlying hazards. After certification, your scope of independent work expands dramatically.
You’ll be authorized to perform intrusive maintenance on explosion-protected equipment, including opening flameproof enclosures, replacing internal components, and verifying integrity after repair. This work requires understanding flamepath dimensions, surface finish requirements, and how various failure modes could compromise explosion protection.
Cable gland installation and replacement becomes part of your regular duties. You’ll need to select appropriate certified glands, verify ingress protection ratings, and ensure proper sealing and earthing continuity. A simple cable termination that takes ten minutes on standard equipment might require thirty minutes in an Ex-rated junction box due to the additional verification steps.
Routine inspections take on new importance. You’re no longer just checking if equipment runs—you’re verifying that every aspect of the explosion protection remains intact. This includes examining enclosure gaskets for degradation, checking cable entry seals for compression set, verifying temperature ratings haven’t been exceeded, and confirming all certification markings remain legible.
Preventive maintenance tasks expand to include specialized procedures like flamepath cleaning, gasket replacement with certified materials, and verification testing after any intrusive work. You become responsible for maintaining detailed records of all maintenance activities, including photographs and measurements that demonstrate continued compliance.

Inspection Grades and Reporting Requirements
IECEx introduces a structured approach to inspections with three distinct grades—Visual, Close, and Detailed. Understanding these levels and when to apply each becomes a core competency after certification.
Visual inspections can be performed without de-energizing equipment and involve external examination for obvious damage, correct certification marking, environmental degradation, and any unauthorized modifications. These typically occur during routine rounds and take just a few minutes per item.
Close inspections require equipment to be isolated and may involve opening enclosures without complete disassembly. You examine internal components, check electrical connections for tightness, verify correct fusing, inspect wiring for damage or deterioration, and confirm that no unauthorized changes have been made. These inspections usually happen annually for critical equipment.
Detailed inspections involve complete disassembly, measurement of critical dimensions like flamepath gaps, testing of electrical parameters, verification of component specifications, and thorough examination of all protection features. This level of inspection typically occurs every three to six years depending on the operating environment and equipment criticality.
Your reporting responsibilities increase significantly. Simple checkmarks on a form are no longer sufficient. You need to document specific measurements, photograph conditions before and after maintenance, record environmental factors like ambient temperature and humidity, and provide detailed descriptions of any deficiencies found.
When you identify issues, your report must include the severity classification, immediate actions taken, recommendations for corrective measures, and timeline for repairs. This documentation serves legal and regulatory purposes, so accuracy and completeness become essential.
Career and Salary Impact in GCC
The financial impact of IECEx certification in the Gulf region is substantial and measurable. Based on current market data across UAE, Saudi Arabia, Qatar, and Kuwait, certified maintenance engineers command salary premiums of 15-30% over their non-certified peers performing similar work.
Entry-level maintenance engineers without IECEx certification in the GCC typically earn between AED 8,000-12,000 monthly. With IECEx certification, that range increases to AED 10,000-15,000 for the same experience level. The gap widens at senior levels, where certified professionals can command AED 18,000-25,000 monthly compared to AED 13,000-18,000 for non-certified counterparts.
Beyond direct salary increases, certification opens access to positions previously unavailable. Supervisor and lead maintenance engineer roles in oil and gas, petrochemical, and pharmaceutical facilities often list IECEx certification as mandatory rather than preferred. Without it, you’re simply not considered regardless of your other qualifications.
Contract opportunities expand significantly. Major projects requiring shutdowns, turnarounds, or commissioning activities actively seek certified personnel and pay premium day rates. Many certified engineers supplement their regular positions with weekend or vacation contract work that wouldn’t be available without certification.
Job security improves markedly. During economic downturns, companies retain certified staff while non-certified positions face cuts. The scarcity of properly trained personnel means you become more valuable and harder to replace.
Career progression accelerates as well. The typical pathway from maintenance technician to maintenance engineer to senior engineer that might take eight to ten years without certification can compress to five to seven years with IECEx credentials, assuming strong performance.
International mobility increases substantially. IECEx certification is globally recognized, making it easier to secure positions across different countries and regions. For engineers seeking to work in Europe, Asia-Pacific, or other markets, IECEx provides immediate credential recognition that smooths visa and work permit processes.

The investment in IECEx certification typically pays for itself within six to twelve months through increased earning potential, expanded job opportunities, and accelerated career progression. For maintenance engineers working in industries with hazardous areas, it’s no longer optional—it’s essential for career growth and professional development.
