Whether it’s fallen powerlines, electric shock or electrical fires, we provide some important information on what to do in an emergency.
Strong winds, vehicle accidents and falling trees can cause powerlines to become dislodged from their attachment point. Power lines that have fallen to the ground should always be assumed to be live – that is, electrically charged. Live lines can cause death or injury, even if a person does not touch the conductor directly.
In the case where a power line has fallen on a vehicle, it is safest for the occupants to remain inside the vehicle. Report the incident to Emergency Services and CitiPower or Powercor so that power can be switched off in the area.
In some circumstances it is not safe to remain inside a vehicle that has come into contact with a power line – for example, if the vehicle has caught fire. For such cases, occupants should jump from the vehicle, landing with their feet together, avoiding touching both the ground and metal parts of the vehicle at the same time. They should then distance themselves from the site by taking small jumps with feet together.
Electric shock occurs when a person comes into contact with an electrical source. Depending on the amount electrical current flowing through the body, electric shock can damage the skin and internal organs. Furthermore, electrical contact can cause muscle contraction, preventing the victim from releasing their grip on an electrical source. If shocks are felt around the home, including minor tingles on taps, a qualified electrician should be called to investigate.
Poor internal wiring or faulty appliances are the main cause of electric shock around the home. To reduce the hazard, never use damaged electrical appliances and ensure that any electrical work is performed by a qualified electrician. Consideration should be given to have a qualified electrician install safety switches on light and power circuits.
In going to the aid of a person suffering from an electric shock you are putting yourself at risk. Direct contact with the victim can cause electric shock to the rescuer. Power should be switched off at the mains supply point before providing assistance. In cases where a victim needs to be immediately removed from an electrical source, push them free with a wooden broom handle or your foot, if wearing shoes. Take extra care if incident occurs in or near water as water can become electrically charged.
All electrical shock injuries should be treated seriously. If the casualty is not breathing call 000 and commence CPR immediately. For less severe electric shock injuries, see your doctor for a health check.
Electrical fires can be caused by incorrectly installed wiring or defective appliances.
Customers should ensure that the wiring of premises is conducted by a qualified electrician. For homes that are more than 25 years old, internal wiring may be in poor condition and can be checked by an electrical contractor. Additionally, if fuses blow or safety switches operate frequently, wiring systems and appliances should be inspected.
To reduce the risk of electrical fires, service appliances regularly and dispose of any items with visible defects such as a damaged cord. Electric blankets in particular should be checked frequently.
If an electrical fire occurs never attempt to extinguish it with water as this will put you at risk of electrocution. Instead, respond to a small electrical fire by turning off power to the source and using a fire blanket or dry chemical fire extinguisher. For larger electrical fires, immediately leave the property and dial 000.
