What must be done to electric power tools for safety?

Proper grounding of electric power tools is essential for safety because it helps to prevent electric shock. When tools are grounded, any stray voltage or electricity that could leak from the tool is directed safely into the ground rather than through a person's body. This connection is an important safety measure that mitigates the risks associated with using electric tools, especially in wet or damp environments where the risk of shock is inherently higher.

While proper maintenance, charging, and storage of tools are crucial for their effective operation and longevity, grounding directly addresses the immediate risk of electrical hazards that can occur during use. This safety feature is fundamental to ensuring the protection of operators and bystanders alike when working with electric tools.
