In this table, "electrial fires" includes all fires where the source of ignition was electrically powered, and the cause of the fire was a faulty power supply, faulty leads or a faulty appliance. The data do not include fires caused by misuse of electrically-powered equipment or appliances.
"Casualties" includes fatalities but not people who were simply recommended to seek precautionary medical advice after a fire, and/or who only received first aid at the scene.
While the overall incidence of fire continues to fall, the number of some types of electrical fire is increasing. We are working with Fire and Rescue Authorities and others to understand and address these trends.
