About This Quiz
Check the decisions that prevent wheel breakage and loss of control during grinding and cutting. These 25 original questions cover accessory compatibility, inspection, mounting, guards, safe operation, dust and protective equipment.
Scope and independent practice
Independent practice material, not an abrasive-wheel mounting qualification or practical competency assessment. This quiz uses HSE guidance for Great Britain. Follow current local requirements and the wheel and machine manufacturers' instructions. Ring testing and mounting arrangements depend on wheel type; one method does not suit every product.
How to use this quiz
Select one best answer and review the explanation. The practice pass mark is 70%, with shuffled answers and retakes. Never use an unknown, damaged or incompatible wheel to test a theory from a quiz. Obtain task-specific training and stop when safe suitability cannot be established.
