CSCS Health and Safety Test Questions

For this CSCS mock test, we’ll be looking at some common practice questions that are covered in the “Electrical safety and hand-held tools and equipment” section of the CSCS test revision book.

Like all of our other CSCS health and safety mock tests, our goal is to provide you with practice questions that are identical to the ones you encounter when taking your test so you can pass the first time and get your CSCS card.

If you’re preparing to take the test for your CSCS labourer card then you’ll be pleased to know that these practice questions are similar to the ones you’re going to face.
