Learning objectives:

The participants can describe the health and safety risks associated with working with a grinder and how to mitigate those risks (Knowledge, basic level) The participants can act independently in safely performing the accurate grinding of composite materials to reveal the fibre orientation, and create overlaps and/or scarf joints to existing material prior to applying repair layers (Ability, intermediate level)

Training staff shall:

Lead a discussion about the health and safety risks associated with working with a grinder by considering the ergonomic implications, including vibration, the dust produced, the electrical hazard, flying debris, noise and the risks posed by high-speed rotating tools Demonstrate how to mitigate those risks by means of body positioning, adequate breaks, correct PPE, pre-use tool inspection, and electrical safety devices such as residual current devices

Explain the different grades of grinding disc available

Demonstrate how to recognise and replace a worn grinding disc

Demonstrate how to safely use a grinder to accurately grind a composite structure to reveal the fibre orientation, and create overlaps and/or scarf joints of the correct dimensions in each layer of laminate

Facilitate practice to improve the participants’ ability to:

a. select and correctly use the appropriate PPE for the task and perform a pre-use tool inspection before working with a grinder

b. recognise and replace a worn-out grinding disc

c. safely use a grinder to accurately grind composite materials to reveal the fibre orientation, and create overlaps and/or scarf joints of the correct dimensions in each layer of laminate

The participants shall:

Engage in a discussion and share their understanding of the health and safety risks associated with working with a grinder Practice the ability to select and correctly use the appropriate PPE for the task and perform a pre-use tool inspection before working with a grinder

Practice the ability to recognise and replace a worn-out grinding disc

Practice the ability to safely use a grinder to accurately grind composite materials to reveal the fibre orientation, and create overlaps and/or scarf joints of the correct dimensions in each layer of laminate

Training staff shall:

Give constructive feedback on the participants’ above practice

NOTE:

These skills and abilities shall be assessed in each of the following repair exercises.
