Preventing Electrical Hazard
Electrocutions are one of the greatest hazards on construction sites. When in direct contact with electric high voltage equipment, such as overhead powerlines or transformer cabins, electrocution can cause death by cardiac arrest. Electricity flows through conductors. Conductors include metals, water, earth, but also the human body. When electrical equipment is functioning properly, the circuit is maintained between the tool, the wires and the electric source.
However, in case of a malfunctioning machine or circuit, the operator can become part of the electric circuit. When in direct contact with a “live” wire, a person can feel a tingling sensation, over an intense electric shock, to ultimately a fatal electrocution, depending on the power, frequency and type (AC/DC) of electric source. Voltages over 50V AC or 120V DC are considered hazardous.
