Final answer:
Electrical appliances and tools should be kept away from water to prevent electrical shocks and thermal hazards. Safety devices like circuit breakers and proper grounding help to mitigate these risks.
Step-by-step explanation:
All electrical appliances and tools should be stored safely when in proximity to C) Water.
Electrical safety systems and devices are crucial for preventing thermal and shock hazards. One significant risk when dealing with electricity is the potential danger that occurs when electrical devices come into contact with water. Such contact can lead to electrical shocks or even thermal hazards due to potential short circuits leading to overheating or fires. Therefore, it is essential to keep electrical appliances and tools away from water and other conductive substances to ensure safety.
Circuit breakers, fuses, and the three-wire system are examples of safety measures designed to guard against these hazards, by interrupting excessive currents and providing proper grounding, respectively.
