DAILY EX | Training is Not Competence
Attending an Ex course does not mean a person understood explosion protection, and understanding does not mean they can apply it when a decision is needed. This article separates attendance, knowledge and competence, sets out where the trainer’s responsibility ends and the employer’s begins, and proposes assessment built on realistic scenarios rather than repeated definitions: a damaged flamepath, a dust-covered area, a replacement motor with different marking. It closes on the operational view, where two hundred attendance certificates say very little about an organisation’s actual capability to maintain explosion protection.

DAILY EX | Training is Not Competence
When we teach explosion protection, how do we know that people actually understand?
Attending an Ex training course does not automatically mean that someone has understood explosion protection. And understanding does not necessarily mean that the person can apply what they have learned.
This is something I believe we need to discuss more openly within the explosion protection community.
As trainers, we spend considerable time preparing presentations, explaining protection concepts, discussing ATEX and IECEx requirements, and introducing the IEC/EN 60079 and ISO 80079 series.
We explain hazardous area classification, ignition sources, equipment selection, installation requirements, inspection, maintenance and repair.
At the end of the training, participants receive a certificate.
But there is a question we should ask ourselves: Have we actually verified that they learned something?
And perhaps more importantly: Can they apply that knowledge when making decisions in a potentially explosive atmosphere?
The difference between attendance, knowledge and competence
These three concepts are frequently confused.
Attendance confirms that someone participated in a training activity.
Knowledge means that the person has understood and retained the relevant information.
Competence goes further. It involves the ability to apply appropriate knowledge and skills to perform a defined task correctly, taking account of the working environment, responsibilities and limitations.
A person may know what Ex d means without being competent to inspect a flameproof enclosure.
Someone may correctly explain intrinsic safety without being able to verify an intrinsically safe circuit.
And a maintenance technician may recognize an Ex marking without understanding the consequences of replacing a certified component with an apparently equivalent alternative.
These differences matter because explosion protection is not simply an academic subject.
Incorrect application of Ex knowledge can introduce an ignition source into an environment where an explosive atmosphere may be present.
Is the trainer responsible for verifying understanding?
In my view, yes.
If I deliver explosion protection training, my responsibility should not end when I finish the final presentation.
I should make a reasonable effort to establish whether participants have understood the essential learning objectives.
However, we must distinguish between the trainer's responsibility and the employer's responsibility.
The trainer is responsible for delivering appropriate instruction and, where assessment is included, conducting a meaningful evaluation.
The employer or operator remains responsible for ensuring that individuals assigned Ex-related tasks possess the necessary competence and are authorised to perform those tasks.
A training certificate alone does not transfer that responsibility.
This distinction is consistent with the competence principles addressed in IEC 60079-14, IEC 60079-17 and the IECEx Certification of Personnel Competence (CoPC) scheme.
Importantly, not every awareness course needs to become a formal personnel certification examination.
The depth of assessment should correspond to the learning objectives and the consequences of getting the task wrong.
How should we verify that learning has taken place?
I believe the assessment should move beyond asking participants to repeat definitions.
For example, instead of asking:
What does Ex d mean?
We could present a photograph of a flameproof enclosure with a damaged flamepath and ask:
What would you do before returning this equipment to service?
Instead of asking:
What is Zone 22?
We could describe a sugar-processing facility with visible combustible dust accumulation and unsuitable electrical equipment.
Then ask: Would you allow operations to continue? What information would you need before making that decision?
Or consider a maintenance technician replacing an Ex-certified motor.
The replacement motor has the same power rating, voltage and mounting dimensions.
But its Ex marking differs.
Can it be installed? Who should verify its suitability? What documentation must be checked?
These questions reveal something that a simple multiple-choice examination may not.
They demonstrate whether the participant can recognize a problem, identify missing information, understand the consequences and select an appropriate course of action.
Of course, written questions remain useful. But for practical Ex tasks, they should be complemented by demonstrations, observations, realistic scenarios or other suitable assessment methods.
What if the participant does not understand?
This is where training becomes particularly important.
If someone cannot demonstrate the required understanding, issuing the same certificate as everyone else without qualification may create a misleading impression.
Instead, we should identify the knowledge gap, provide additional explanation or practice, and reassess the relevant learning objectives.
Where competence has not been demonstrated, the training record should make that limitation clear.
For safety-critical tasks, unsuccessful assessment should mean that competence has not yet been established for that task.
This is not about making examinations unnecessarily difficult.
It is about ensuring that the assessment has a meaningful relationship with the work the person will perform.
The Head of Operations perspective
For operational management, the issue extends beyond the classroom.
Imagine an installation with 200 employees and contractors who have completed explosion protection awareness training.
All 200 have attendance certificates.
But can the organization demonstrate that the relevant personnel understand:
* When an Ex defect must be reported and escalated?
* Why apparently minor modifications may require reassessment?
* Which activities require specific Ex competence and authorization?
* When equipment must not be returned to service?
* Where to find the applicable certificates, instructions and inspection records?
If these questions cannot be answered, the number of training certificates tells us very little about the organization's actual capability to maintain explosion protection.
Training effectiveness should therefore become part of operational assurance.
This means defining learning objectives, selecting suitable assessment methods, recording results, addressing gaps and periodically verifying that the required competence is maintained.
It also means recognizing that competence is task-specific.
An experienced Ex inspector is not automatically competent to repair Ex equipment. A qualified electrical engineer is not automatically competent in non-electrical ignition source assessment.
Competence must match the task, the protection concept and the actual working conditions.
The question we should ask after every Ex training course
I would like to challenge both trainers and employers to reconsider what successful training actually means.
Is success measured by the number of participants?
By the number of certificates issued?
By positive feedback?
Or by whether people can recognize hazardous conditions and make technically correct decisions when it matters?
For me, the answer is clear.
Training is an input. Learning is an outcome. Competence must be demonstrated.
And in explosion protection, that distinction can make the difference between maintaining a safe installation and unknowingly introducing the conditions for a serious incident.
One final question for Ex trainers
When you deliver explosion protection training, how do you verify that participants have genuinely understood and can apply what you have taught?
Do you rely on written examinations, practical assessments, workplace observation, or a combination?
And what do you do when someone attends the entire course but cannot demonstrate the required understanding?
I would be interested in hearing how other Ex professionals approach this challenge.
Because our responsibility should not end with the presentation.
The objective is not to produce more certificates. It is to develop people who can make the right decisions. Lifelong Ex. Operational Ex.
