The major risk associated with electricity is the risk of electrocution, which can occur as a result of faulty equipment or through inadvertence or carelessness.
Never use electrical appliances (light switches, hairdryers, shavers, radios, etc.) with your feet in water or your hands wet: you considerably increase the risk of electrocution.
Know where the main circuit breaker is. It's usually near the electrical distribution board. The circuit breaker cuts off the current to your entire electrical installation.
Medium- and high-voltage overhead power lines blend naturally into the landscape and we tend not to notice them any more. However, there is a real danger beneath power lines, as they are only 6 metres above the ground.
