E-learning Training M0 - Mechanical Authorization
The Mechanical Authorisation M0 training course is essential for all personnel working in close proximity to mechanical or thermodynamic devices, or working on industrial sites such as EDF/ERDF power stations, refineries, industrial sites or production units.
This training complies with Decree No. 88-1056 of 14/11/1988 and the RPP (Regulations for the Prevention of Occupational Risks). Its aim is to raise awareness among non-mechanical personnel of the mechanical risks present in industrial and technical environments.
At the end of the training course, and if they receive a favourable assessment, participants receive a training certificate and an M0 mechanical accreditation, recognised by their employer.
The e-learning format, accessible 24 hours a day, anywhere, allows participants to complete this training course in around two hours, quickly and efficiently, while complying with legal safety requirements.

What is mechanical authorisation?
Mechanical accreditation is a certificate or authorisation issued by an employer that allows a person to:
work on or near mechanical equipment in an industrial environment (such as an EDF power station),
in compliance with specific safety rules,
and according to their level of skills and responsibilities.
It is not simply theoretical training: it is official recognition that the person can work safely in mechanical areas.
Who is the M0 mechanical accreditation intended for?
The M0 accreditation is intended for all persons working in an EDF mechanical environment but not performing technical tasks on operating equipment.
EDF employees providing support on mechanical worksites.
Service providers and subcontractors (external companies) working on EDF sites.
Support or maintenance personnel: assistant mechanics, maintenance workers, visual inspectors, pipe fitters, painters, industrial cleaners.
How long are training courses and qualifications valid for?
Initial training for M0 mechanical certification is generally valid for three years.
After this period, refresher training or retraining is mandatory to maintain certification.
What are the penalties for not having a mechanical licence?
Not having the right mechanical authorisation to work on an EDF site can have serious consequences, both in terms of safety and in terms of regulations and disciplinary action.
- Safety risks
Working without mechanical authorisation exposes the person to:
Risks of serious accidents: crushing, shearing, impact, projections, burns, injuries from moving machinery.
Risks to other workers: an untrained person may cause an incident or prevent the appropriate response in the event of a problem.
Risk of non-compliance with EDF procedures, which are strict on mechanical safety.
- Disciplinary and contractual sanctions
According to EDF policy and the Labour Code:
- Prohibition of access to the site: unauthorised personnel may be denied access to mechanical areas.
- Suspension of duties: the employee or contractor may be suspended until authorisation is obtained.
- Internal sanctions: warning, suspension, or even dismissal in the event of repeated or serious non-compliance.
- For contractors: contractual sanctions, financial penalties, or termination of the contract with EDF.
Legal sanctions
- Lack of training or authorisation may be considered a breach of the safety obligation under the Labour Code (Art. L4121-1 et seq.).
- In the event of an accident: the company or employee may be held civilly and criminally liable.
- For EDF sites, failure to comply with authorisation requirements may trigger internal investigations and inspections by the Nuclear Safety Authority (ASN) if the site is nuclear.
M0 training via e-learning?
The M0 mechanical accreditation e-learning course (distance learning, online) offers several significant advantages, especially for service providers working on EDF sites.
- Time savings and flexibility
The course can be completed at your own pace, from any location (office, home, construction site) via our LMS, which is accessible 24 hours a day.
There is no need to plan travel or set aside a whole day for your employee.
- Cost reduction
No travel, accommodation or meal expenses.
Less time away from the workplace.
- Interactive and modern teaching methods
Courses presented in the form of video modules, animations, quizzes and practical case studies.
Learners remain active and interact with the content.
- Better knowledge retention
Ability to go back and sequence learning.
Learners progress at their own pace, which promotes lasting understanding.
Regular quizzes and exercises help to reinforce prevention and safety reflexes.
- Traceability and compliance
Traceability of connections, scores and certificates.
Certificate of completion
Obtain a certificate of completion and accreditation (to be completed and validated by the employer).
- Environmentally friendly and modern - CSR approach
Reduction in the carbon footprint associated with travel.
Digital format in line with the zero paper/sustainable development approach.
