1. Lifting the tool a few times to maximum height in order to ensure that the tool is properly harnessed.
2. Preventing vertical freedom of movement of the arms and of the tool.
3. Correct answer: Preventing horizontal freedom of movement of the arms and of the tool.
4. Securing the harnessed tool with special security chains.
