Circuit breakers only shut off the power supply in the event of an overload or short circuit, and they do not provide personal protection. It’s important to remember that circuit breakers should only be used as a backup for protection; the primary protection for workers is proper PPE.
Myth 3: Only high voltage is dangerous
Many people erroneously believe that low voltage is safe and that only high voltage is dangerous. However, this is not accurate. Any voltage level can be potentially life-threatening if it comes into contact with your body or skin. It can cause electric shock, electrocution, or arc flash injuries. Moreover, low voltage can actually be more dangerous than high voltage because people tend to underestimate the danger level and become complacent.
Myth 4: Turning off the power supply is enough
Another common myth is that turning off the power supply to an electrical circuit is enough for safety. However, this is not always the case. Sometimes, current can continue to flow even when the power supply is turned off. This is because some electrical devices, such as capacitors and transformers, can store electrical energy and release it even when the power is off. Before starting any electrical maintenance, it’s best to check with a qualified electrician or use a voltage tester to ensure that the circuit is de-energized.
Myth 5: You can’t be shocked if you’re not touching two wires at once
An erroneous belief is that you can’t be shocked if you’re not touching two wires at once. The truth is that you can receive an electrical shock just by touching a single wire if the electrical potential difference is high enough to overcome your body’s resistance. Even a low voltage, such as 120 volts, can be hazardous if the electrical current comes into contact with your skin.
In conclusion, electrical safety is critical to protecting you and others from harm. By understanding the truth behind these popular myths, you can take the necessary precautions to ensure that you maintain a safer environment while working with electricity. Remember, when in doubt, it’s better to ask a qualified electrician or other professionals in the field to make sure you’re taking the best approach.
