Putting a connected toaster or any electric device in the bathtub with water is extremely dangerous and can lead to electrocution because the human body is a good conductor of electricity. When an electric device comes into contact with water in a confined space like a bathtub, it creates an electric circuit. If a person is in the water and comes into contact with the electrified water or the device itself, electricity can pass through their body, causing an electric shock or electrocution.
In contrast, a swimming pool is a different environment altogether, and the risk of electrocution in a swimming pool is generally lower due to several factors:
Size and Dilution: Swimming pools are much larger than bathtubs, and the water is well-distributed, leading to greater dilution of any electric current. The larger volume of water in the pool means that any electric current that enters the water would be spread out over a much larger area, reducing its intensity and the risk of serious harm.
Grounding and Safety Measures: Public swimming pools are required to follow strict safety regulations and are equipped with electrical safety systems. Pool equipment and electrical installations are usually placed away from the water, and the components are designed to be waterproof and meet safety standards.
GFCI Protection: Many modern swimming pools are equipped with ground fault circuit interrupter (GFCI) outlets or breakers. GFCIs are designed to quickly detect imbalances in electrical currents and shut off power to the circuit if they detect any leakage or fault, minimizing the risk of electric shock.
Regular Inspections: Public swimming pools undergo regular inspections to ensure they meet safety standards and that all electrical equipment is in good working condition.
Despite these safety measures, it's important to remember that there is still some risk associated with using electrical devices around a swimming pool, especially if they are not designed for outdoor or wet environments. Using non-waterproof or faulty electrical devices near the pool area can still pose dangers, so it's essential to exercise caution and use certified and appropriate equipment.
In any case, it is never safe to intentionally immerse or use electrical devices in the water, whether in a bathtub, swimming pool, or any other environment with water, as the risks of electric shock and electrocution are very real and can be life-threatening. Always keep electrical devices away from water and use them only as intended in dry conditions to ensure your safety.
