Technical training
Blade Repair Standard / V5 23022026
During practical training, pose questions about the hazards and risks from repetitive manual handling and how to mitigate short- and long-term injuries from repetitive manual handling
Provide feedback to the participants and present additional procedures and risk-mitigating actions
Outline how the surface profile affects the aerodynamic performance of the blade. Explain how blade repair work can change the surface profile, leading to reduced performance and loss of production
Explain how the surface finish affects the adhesion of subsequent repair layers such as filler and paint. Indicate that the surface finish varies for different products, and that the required finish is detailed in the manufacturer’s work instructions and the technical data sheet for the product
Explain the different grades of sanding disc available
Demonstrate how to recognise and replace a worn sanding disc
Demonstrate how to safely use a sander and select an appropriate sanding disc first; to remove excess filler to match the surrounding aerodynamic profile of the blade; and secondly, to create the correct surface finish for adhesion of subsequent repair layers Ask the participants relevant questions about how the surface profile of a repair affects the aerodynamic performance of the blade, and explain how the surface finish affects the adhesion of subsequent repair layers
The participants shall:
Engage in a discussion and share their understanding of the health and safety risks associated with working with a sander, such as: ergonomic hazards, flying debris and dust, exposed moving parts at high speed, noise, vibration, and electricity
Take active part in a discussion on short- and long-term injuries from repetitive manual handling and possible mitigating actions
Practise the following safety procedures to reduce the risks associated with sanders:
a.
Recognize and replace a worn sanding disc
b. Safely operate a sander to remove excess filler to match the surrounding aerodynamic profile and to create the correct surface finish for adhesion of subsequent repair layers
c. Control hazards associated with a sander, including ergonomic hazards, flying debris and dust, exposed moving parts at high speed, noise, vibration, and electricity
In the practical training, apply their knowledge on short- and long-term injuries from repetitive manual handling and suggest actions relevant in the wind industry to mitigate short- and long-term injuries from repetitive manual handling
