Figures show that, since January 1, NSW Ambulance paramedics responded to at least 123 calls for electric shock/electrocution.
NSW Ambulance Inspector Giles Buchanan said danger commonly lurked about the home, with most incidents treated by paramedics involving shocks from faulty appliances and power cords.
"We've had people who have received jolts from their fridge, toaster, microwave oven, hair straightener, computer - just about every household appliance," Inspector Buchanan said.
He said many cases appeared to involve tradesmen, however there were also non-professionals attempting work in the home who were out of their depth.
Inspector Buchanan said even mild shocks had the potential to cause serious injury and even death, particularly in people who were prone to irregular heart rhythms.
"Irrespective of the voltage, electric shock can be fatal. In the case of heart dysrhythmias - particularly if you are susceptible, that extra electrical charge can be enough to stop your heart.
"The shock can also cause fractures which can be quite alarming. You can also be thrown across the room and this can also result in broken bones."
From a safety perspective, Inspector Buchanan advised people to not use appliances that had frayed cords or were faulty in any way, to ensure children were kept well away from power sockets, and check the location of underground cables before digging in the garden.
"Even if a person believes a shock is minor, it is always recommended they talk to their doctor or a medical professional and get it checked out," Inspector Buchanan added.
