Which of the following is crucial for preventing accidents when using hand tools?

Regular maintenance and proper usage are essential for preventing accidents when using hand tools because they ensure that the tools are functioning safely and effectively. Proper usage involves following the manufacturer's guidelines for each tool, which includes using the right tool for the job, employing the correct techniques, and wearing appropriate personal protective equipment (PPE). This helps mitigate the risk of accidents due to misuse or mishandling.

Additionally, regular maintenance is vital to identify wear and tear or defects before they lead to failure during use. This includes checking for physical damage, ensuring cutting edges are sharp, and lubricating moving parts to prevent malfunction or accidental injury. By combining these practices, users can significantly reduce their chances of accidents and injuries while using hand tools.
