CompEx Training Courses for Explosive Atmosphere Safety
Extrainings is a CompEx Certification & Training Centre delivering courses for professionals working in explosive atmospheres across the UAE and Saudi Arabia. With training facilities serving Abu Dhabi, Dubai, Jubail, Dammam, and Riyadh, the centre provides locally accessible pathways to internationally recognised hazardous area qualifications.
CompEx is the global competency scheme for personnel who install, inspect, and maintain electrical equipment in hazardous areas where explosive atmospheres may occur. The scheme validates that technicians understand how to work safely in Ex zones and apply explosion protection methods correctly.
What is CompEx Training?
CompEx (Competency in Explosive Atmospheres) is an internationally recognized personnel certification scheme based on IEC 60079 standards and ISO/IEC 17024 requirements. It validates the skills of electrical personnel working in potentially explosive atmospheres.
The program combines theoretical learning with hands-on practical tasks and formal assessment. Candidates learn to install, inspect, and maintain Ex equipment in hazardous locations, covering both gas and vapours and combustible dust environments.
Training addresses classified zones:
- Gas/Vapours: Zone 0, 1, 2
- Dust: Zone 20, 21, 22
- Hazardous area classification and area classification zones
- Ignition sources control methods
- Explosion protection methods (Ex d, Ex e, Ex i, and others)
- Ex equipment installation, inspection and maintenance routines
- International standards including IEC 60079 series
| Course | Focus | Typical Job Role |
|---|---|---|
| ExF Foundation | Awareness of explosive atmospheres and Ex concepts | Non-electrical supervisors, support staff |
| Ex01–Ex04 | Gas and vapours installation, inspection, maintenance | Electrical technicians, E&I engineers |
| Ex05–Ex06 | Combustible dust hazardous areas | Technicians in powder, grain, pharmaceutical plants |
| Ex01R–Ex04R | 5-year refresher and knowledge update | Experienced practitioners renewing certification |
Why Explosive Atmosphere Safety Matters in UAE & KSA
The UAE and Saudi Arabia host large concentrations of oil, gas, and petrochemical facilities (e.g., Abu Dhabi Ruwais, Dubai Jebel Ali, Ras Tanura, Jubail, Yanbu). Explosive atmospheres arise from:
- Gas leaks in pumps, flanges, or process equipment
- Flammable vapour release from storage tanks or loading racks
- Dust accumulation in silos, bagging lines, and filter houses
Electrical installations in these zones require trained personnel. Improper work can create ignition sources, potentially triggering catastrophic explosions.
Common hazardous scenarios:
- Gas vapour accumulation at LNG loading jetties and pump rooms
- Hydrocarbon leaks near compressor buildings and metering stations
- Dust build-up in grain elevator legs and flour mill filter houses
- Solvent vapours in paint manufacturing and chemical blending areas
CompEx certification ensures compliance with process safety rules, insurance requirements, and regulatory expectations.
Where CompEx Certification is Required
CompEx certification is frequently specified by operators and EPC contractors in Gulf industrial sectors.
Industries with common explosive atmospheres include:
Oil and gas production and separation plants
Refineries and tank farms
LNG liquefaction and regasification terminals
Petrochemical and hydrogen plants
Fuel storage depots and chemical warehouses
Grain, flour mills, and pharmaceutical plants
Food and beverage spray-drying facilities
Paint and solvent manufacturing
Contractors and maintenance companies require personnel with verified competence in hazardous area electrical work.
Who Should Take CompEx Training?
Typical roles include:
Electrical technicians and industrial electricians
Instrumentation technicians and E&I engineers
Maintenance engineers performing preventive maintenance
Hazardous area inspectors and QA/QC engineers
Site supervisors and commissioning engineers
Shutdown and turnaround team leaders
HSE and safety officers authorising Ex work
Early-career electrical engineers and final-year engineering students in electrical and instrumentation disciplines who want to enter the Ex industry in the UAE or Saudi Arabia also benefit from CompEx as a foundation for their careers.
Non-electrical personnel entering hazardous areas should consider awareness-level courses such as ExF, ExF+, or Ex Awareness for basic understanding.
CompEx Course Structure Explained (ExF, Ex01–Ex06)
Extrainings (KL Training Academy / Kingsmen Group) delivers a structured pathway from awareness through to full practitioner modules, aligned with the CompEx Competence Certification Framework. Each unit builds on the previous, creating a logical progression for technicians and engineers.
The main CompEx units cover different levels and atmosphere types:
- ExF (Foundation) – Explosive atmosphere concepts and Ex zone basics for non-electrical personnel (1 day)
- ExF+ (Foundation Plus) – Extended awareness for personnel near Ex zones (2 days)
- Ex01–Ex04 (Gas and Vapours) – Installation, inspection, and maintenance in gas and vapour hazardous areas (10–15 days)
- Ex05–Ex06 (Combustible Dust) – Dust hazard recognition and equipment handling (5 days)
- Ex01R–Ex04R (Recognised Practitioners Programme) – 5-year refresher with knowledge update and practical exercises (3–5 days)
Each module combines theory, guided practical training on Ex panels, and formal assessment via exams and hands-on tasks.
| Unit | Atmosphere Type | Typical Duration | Main Focus | Ideal For |
|---|---|---|---|---|
| ExF | General awareness | 1 day | Explosive atmosphere concepts, Ex zone basics | Supervisors, support staff |
| ExF+ | General awareness | 2 days | Extended foundation for personnel near Ex areas | Operations, mechanical teams |
| Ex01–Ex04 | Gas and vapours | 10–15 days total | Installation, inspection, maintenance | Electrical technicians, E&I engineers |
| Ex05–Ex06 | Combustible dust | 5 days | Dust hazard recognition, equipment selection | Technicians in powder industries |

Extrainings (KL Training Academy / Kingsmen Group) offers flexible scheduling in the UAE and KSA, including weekday blocks and arrangements that accommodate shutdown teams and shift workers. Courses are typically delivered at dedicated training centres with equipment that replicates real field installations.
How to Choose the Right CompEx Course
The right CompEx path depends on your existing qualifications, work experience, and the type of hazardous atmosphere you encounter on site. Gas and vapours training differs from combustible dust training, and the starting point varies based on background.
Typical starting points include:
- Newcomers – Start with ExF or Ex Awareness
- Qualified electricians – Begin with Ex01–Ex04 if experienced
- Dust environment workers – Add Ex05–Ex06 as needed
- Practitioners renewing certification – Take Recognised Practitioners Programme (Ex01R–Ex04R)
Eligibility typically requires:
Basic electrical or instrumentation qualification (e.g., City & Guilds 2365, NVQ Level 3)
Practical workplace experience
Ability to understand technical English and IEC standards
Extrainings (KL Training Academy / Kingsmen Group) can review CVs or job descriptions to advise on the most suitable module for your role and industry.
CompEx vs IECEx vs ATEX
CompEx, IECEx, and ATEX are often mentioned together in discussions about explosive atmosphere safety, but they serve different purposes: personnel competence, equipment certification, and regulatory frameworks.
| Scheme | Main Focus | Covers Who/What | Geographic Use | Typical Use in UAE/KSA |
|---|---|---|---|---|
| CompEx | Personnel competence | Individual technicians and engineers | Global (originated UK) | Widely required by operators, EPCs |
| IECEx CoPC | Personnel competence + equipment conformity | Individuals and equipment/systems | International (80+ countries) | Reference for multinational contracts |
| ATEX | Regulatory framework | Equipment and workplace safety | European Union | Principles adopted, directive not enforced |
Many certified professionals in the UAE and Saudi Arabia hold CompEx for local roles and may later add IECEx CoPC for international opportunities or projects with specific multinational requirements. The training content overlaps significantly, as both schemes are grounded in IEC 60079 standards.
