Course Information
Overview:
CompEx Ex11 Mechanical & Flange Integrity Core is the recognised UK qualification for mechanical technicians and fitters who install, inspect and maintain equipment in hazardous areas where flammable gases, vapours or dusts may be present. The course addresses the specific risks that mechanical work can introduce, such as friction, impact, static and loss of containment through poorly made flange joints. Delegates learn how to select and assemble gaskets, control bolt loads, verify joint integrity and document work in line with current industry practice. Successful completion demonstrates competence to employers and site operators that the individual can carry out mechanical tasks without creating an ignition source or compromising the integrity of the process plant.
Who Should Attend?
This course is designed for:
- Mechanical fitters and technicians working on process plant
- Maintenance engineers in oil, gas and petrochemical facilities
- Flange technicians and joint integrity specialists
- Site-based mechanical supervisors responsible for Ex equipment
- Contractors carrying out shutdown and turnaround work in zoned areas
What You Will Learn
By the end of the course you will be able to:
- How mechanical equipment can become an ignition source in explosive atmospheres
- Correct selection and assembly of flanges, gaskets and bolting systems
- Methods for achieving and verifying correct bolt load and joint integrity
- Inspection and maintenance routines that minimise leakage risk
- Documentation and reporting requirements for mechanical work in hazardous areas
- Safe use of hand and power tools within zoned locations
Course Agenda
Overview:
The course runs over three days and blends short theory sessions with extended practical workshops. Day one covers legislation and ignition mechanisms, day two focuses on flange technology and assembly techniques, and day three includes assessment of both knowledge and practical skills.
Key Modules Covered
What you will learn:
- Legislation, standards and hazardous area classification
- Mechanical ignition sources and their control
- Flange types, gaskets, bolting and joint preparation
- Controlled tightening methods and integrity verification
- Inspection, maintenance and fault-finding on mechanical Ex equipment
- Practical flange assembly exercises and final assessment
Private Courses On-site
CompEx Ex11 Ex Mechanical & Flange Integrity Core training is also available as a dedicated course, at your premises, and on a date and time of your choosing. Advantages of group / private course is the convenience of candidates being in familiar surroundings and not having to travel, the lowest price, and the ability to have the course tailored to your own application.

Accreditation & Next Steps
What you will achieve as a result:
Delegates who pass both the written test and practical assessment receive a CompEx Ex11 certificate. This qualification is normally valid for five years. Before expiry, certificate holders must complete the appropriate refresher or re-assessment module to maintain their registration.
Frequently Asked Questions
Most commonly asked CompEx Ex11 Ex Mechanical & Flange Integrity Core questions:
The standard course is delivered over three consecutive days, combining theory and practical workshops with assessment on the final day.
Delegates should already hold a recognised mechanical trade qualification or have substantial relevant work experience. Basic site safety awareness is expected.
Delegates complete flange assembly tasks under observation, demonstrating correct gasket selection, bolt tightening sequence and joint integrity checks.
The CompEx Ex11 certificate is valid for five years from the date of issue.
Yes, a one-day refresher or re-assessment module is available for certificate holders approaching expiry.
You should bring your existing mechanical qualifications, a valid photographic ID and appropriate PPE such as safety boots and high-visibility clothing.
Yes, the syllabus addresses ignition risks and control measures for both gas/vapour and combustible dust explosive atmospheres.
Ex11 focuses exclusively on mechanical equipment, flange joints and associated integrity tasks rather than electrical installation and inspection.
Delegates receive a comprehensive course manual covering standards, procedures and reference data for use after the course.
The certificate is widely recognised by UK operators and contractors in both onshore and offshore hazardous area environments.
Delegates who do not meet the required standard receive feedback and may re-sit the relevant parts of the assessment at a later date.
The practical skills directly support leak-free joint assembly during plant shutdowns, turnarounds and routine maintenance in zoned areas.
Prices per person typically start at £948. Discounts available for multi person or group bookings (depending upon location)
More Information
The training emphasises real workplace scenarios that mechanical personnel encounter during installation, maintenance and inspection activities on process plant. All practical exercises use representative industrial equipment and follow current industry procedures for joint integrity and hazardous area safety.
