Final answer:
Electric tools pose thermal and shock hazards, requiring the use of electrical safety systems for protection.
Explanation:
Electric Hazards: Thermal and Shock
The two most common hazards of electric tools are thermal and shock hazards. Thermal hazards occur when excessive electric power causes undesired heating effects, potentially leading to fires. Shock hazards happen when electric current passes through a person, varying in severity from mild discomfort to life-threatening consequences.
It is essential to implement electrical safety systems and devices to prevent these hazards and ensure user protection.
