4. SCOPE
Global Wind Organisation is a non-profit body founded by the wind turbine manufacturers and owners. Our members strive for an injury free work environment in the wind turbine industry, setting common international standards for safety training and emergency procedures.
This standard describes the requirements for blade repair training that are recommended by the members of GWO. The standard comprises of one module.
GWO recognises trained persons as competent within blade repair in the wind industry. GWO accepts the trained person as possessing the required knowledge, skills, and abilities to stop an unsafe work situation where they, as duty holders, are accountable for safety. This standard has been developed in response to the demand for recognisable blade repair training in the industry and has been prepared in co-operation between the members of GWO based on risk assessments, in-depth descriptions of job roles and tasks relevant to blade repair in the wind industry as well as factual incident and accident statistics from G+ and the wind industry.
Training is verified through GWO’s WINDA database.
General feedback on this document can be sent to info@globalwindsafety.org See globalwindsafety.org on how to raise a complaint about a training provider or report a safety incident occurring during training.
5. GENERAL REQUIREMENTS FOR THE GWO BLADE REPAIR Upon completion of the GWO Blade Repair Standard (BR), participants will be aware of the risks and hazards encountered when working with blade inspection and repair within the wind industry. Furthermore, they will be able to control and mitigate those risks and hazards. The GWO Blade Repair Standard training will also equip participants with the knowledge, skills, and confidence to appropriately respond in the event of a hazardous situation and to increase their safety through proper use of personal protective equipment, emergency equipment, procedures and safe craftsmanship. 5.1 Target Group Personnel who will be working in the wind industry, specifically in relation to composite inspection and repair work. Personnel that perform job functions (that have been risk assessed by their employer or their workplace duty holder) that are defined as functions where composite work training, according to this standard, may mitigate some of the identified hazards and risks. 5.2 Aims and Objectives Training in accordance with this standard will enable participants to support and care for themselves and others working in the wind industry by possessing the knowledge and skills of composite inspection and repair work. Upon completion of the GWO Blade Repair Standard training course, participants will be able to work safely with composite materials while conducting inspection and basic blade repair procedures, thereby

Technical training
Blade Repair Standard / V5 02052025
supporting an overall improvement of the safety for personnel with job functions focussing on composite repair work and inspection in the wind industry.
5.3 Validity Period The blade repair training is an enduring qualification and therefore a validity period does not apply to this training. This assumes that the participants are actively working with composite inspection and repair.
5.4 Course Codes

Technical training
Blade Repair Standard / V5 02052025
3.
Act as first responder in the case of an accident
Supporting staff:
1. A person with a valid first aid qualification shall be present during all practical training. This can be the instructor or an assigned emergency response team
6.2 Practical Training Facilities All facilities shall be maintained and, where appropriate, inspected and tested in accordance with current national legislation and manufacturers’ specification. It is recommended that the facilities reach European standards.
Risk assessments shall be conducted and documented for all training facilities. The training provider shall hold the required permits to operate the facilities.
The learning process is facilitated by comparable elements, comparing the training environment and the participants’ working environment. Comparable elements enhance the application of what is learned. The practical training facilities and the training environment are therefore expected to incorporate as many elements comparable to a real wind turbine working environment as is reasonably practicable. The practical training facility should enable each participant to, individually and/or as part of a team, see, hear and practise the taught subject matter in such a way that it resembles the working practices in a real wind turbine environment.
The following training facility items will be required for the blade repair training:
A workshop area with sufficient:
1. dust extraction to ensure that the amount of dust in the air is kept below 10 milligrams per cubic metre
2.
filtration of extracted air to prevent environmental contamination
3. exposure control measures to limit exposure limits for the instructor and participants to those as stated in the safety data sheet for all materials being used
4. temperature and humidity control to ensure that all materials being used are used within the usage limits specified in the technical data sheet for those materials
5. segregation from classrooms and administrative areas to prevent cross contamination of chemicals
6.
waste segregation to prevent cross contamination
The training provider must ensure that chemical waste is disposed of in accordance with national legislation.
The training provider must provide a changing area between workshop areas and clean areas like classrooms and administration areas where participants and staff can change their shoes to prevent contamination of clean areas with chemicals.
Global Wind Organisation©2025 / www.globalwindsafety.org

The above are the minimum requirements, if national legislation and regulations supersedes this, then they must be followed.
6.3 Training Equipment
The equipment required for training as listed in Annex 1 must be available and must fulfil national legal requirements in the country where the training is taking place.
7. USING THIS STANDARD TO DEVELOP TRAINING The training in this standard is designed around the GWO taxonomy described in the GWO Requirements for Training. Theoretical and practical activities must be delivered according to the defined taxonomic level in order to reach the described learning objectives. When teaching equipment, a generic approach shall be applied aiming to avoid additional potential product specific formal training after completion of this training. However, national or regional legislation, company gap analysis and location specific risk assessments may require additional product specific familiarisation which is the responsibility of the duty holder.
In addition to this, all training based on this standard including all related resources shall, as a minimum, meet the requirements described in the GWO Requirements for Training.
8. ADMINISTRATION AND CERTIFICATION OF MODULE
8.1 Participant Performance Assessment Participants will be assessed by means of direct observation and supplementary oral questions where appropriate (formative evaluation). The participants will also be subjected to written phase tests after theory elements, and again after the close of the training course (summative evaluation). The written tests can consist of multiple choice or descriptive answer questions and shall be set at the same taxonomy level as the objective that they are testing. There shall be at least one question for each lesson in the module.
The written tests shall be conducted in accordance with the following criteria:
1. there shall be an instructor present in the room where written tests are being conducted for the entire duration of the written test
2.
the participants shall not communicate with each other during the test
3. the participants shall not communicate with any persons via email, telephone, Skype (or similar) or social media during the test

Technical training
Blade Repair Standard / V5 02052025
5. where a participant does not understand the meaning of a question or a multiple-choice option, the instructor shall be allowed to help the participant to understand the meaning of the question or the multiple-choice options. The instructor shall not give the participants the correct answers to any test questions
6.
there shall be a time limit of 1½ minutes per question
7. the written test questions cannot be used during the training in such a way that the participants could recognise that they will be test questions
8. each participant must answer at least 70% of written test questions correctly to pass the test
If a participant does not reach the passing criteria in written or observational tests, the instructor shall discuss this with the participant to find out the reason. If this is due to a misunderstanding of a question or due to language difficulties, then the instructor can mark a question as correct provided that the participants is able to demonstrate understanding of the lesson element being tested. This must be documented by the instructor and stored with the tests, control measures and evaluations for the course.
Training providers shall have a documented procedure in place for dealing with participants not meeting the stated learning objectives.
Throughout the entire GWO blade repair course, the instructor will use the participant assessment form (see Requirements for Training) to evaluate the participants’ knowledge and skills, with a high focus on evaluating the participants’ safety awareness and craftsmanship skills.
The instructor shall keep a participant assessment form (or adaptation) for each participant until the completion / evaluation of the blade repair training module.
The participant assessment form (or adaptation) is a final evaluation tool for the instructors to assess participants during practical elements. It allows measurement of the number of violations regarding safety, competency or ability. The participant assessment form shall be used as a progressive evaluation tool to discuss the performance of a participant to guide them to success. It also serves as supporting documentation if a participant passes or fails the module. If a participant fails to meet the demands of the blade repair training module, they can attend a new blade repair training in accordance with the contractual agreement when ordering the training course. The re-entry point is dictated by the stage where the participant left the course or where the instructor deems constructive.
Training providers may adapt the participant assessment form to other media. Training providers must have a documented procedure in place for dealing with participants not meeting the stated learning outcomes.
