Electricity is distributed at high voltages and all lines should be treated as live at all times. Care also needs to be taken around power poles, transformers, and switchgear.
If you’re trimming or removing trees, cleaning or replacing spoutings, painting, repairing roofs or chimneys, or making alterations, be careful when you’re working near overhead power lines or underground cables where they enter your house. These lines are not safe to touch.
The risks when using, or being in contact with electricity are, electric shocks, burns, fire, serious injury and death.
Make sure you look up and look out, watch those overheads, and watch where you dig.
