Show the answer and explanation

Answer: A

  • A. Right: Right. Lower-vibration tools, well-maintained tools and keeping warm all reduce the risk. Gripping harder (statement 2) makes it worse.
  • B. Wrong: Wrong. Statement 2 is not true: HSE says avoid gripping or forcing a tool more than you have to. Statement 4 is true, so it should be included.
  • C. Wrong: Wrong. Statement 2 is not true, and statements 1 and 3 are both true and should be included.
  • D. Wrong: Wrong. Statement 2 is not true. A tighter grip passes more vibration into your hands.

Explanation

Use the right, lowest-vibration tool for the job, report worn or faulty tools, keep warm and dry, take breaks and don't grip harder than you need to.
