Need to know facts about electrocution — prevention and treatment
IT doesn’t really matter how many people it takes to change a lightbulb as long as safety measures, like switching the light switch off beforehand, are in place.
Is an electrical shock always hazardous?
Common household electricity may only cause pain or a spark when you touch it briefly. This does not necessarily require medical treatment unless a heart rhythm disturbance was triggered.
Prolonged contact with an electrical point, however, has the potential to cause general body seizure movement, severe burns, muscle damage, fractures and heart rhythm disturbances. If you are electrocuted in this way, medical attention must be sought even if you feel well afterwards as the muscle damage could lead to kidney failure.
Direct contact with power lines and cables at electrical substations is often fatal.
• Do not overload power points
• Avoid exposed electrical wires
• Stay indoors during lightning storms
• Do not allow children to play with plug points
• Install childproof power points
• Never undertake any electrical work unless you are a trained professional
•Treat all electricity connections and wires as live, even if they were switched off at the distribution board (sometimes referred to as “mains”)
•Never work with electricity in wet areas or use anything electrical in wet conditions. Mowing the lawn or using power tools in wet weather, for example, is dangerous.
•Inspect your household appliances regularly, making sure that the power cords are not cracked or frayed; if an appliance sparks or smokes when it is switched on, replace the appliance immediately; make sure there are no unprotected live wire sources in or around the home
•When there is a power outage, treat all electricity points as live
•Always read an electrical device’s manufacturers manual and do not service electrical parts yourself that are marked for specialist repair only
SIGNS AND SYMPTOMS OF ELECTROCUTION
• Burn wounds
• Injuries, including fractures and spinal injuries caused by muscle contraction and being flung against items
• Heart rhythm disturbances
• Loss of consciousness
• Cardiac arrest
IF SOMEONE HAS BEEN ELECTROCUTED
•Avoid exposure to the electricity source. If possible, switch it off
•Remove the patient from the electrical source to a safe area
•Check the patient’s circulation, airway and breathing
•If there are no signs of life, start CPR immediately
•If a patient is breathing but unconscious, place the person in the recovery position
•Cover the burn wounds with clean, non-absorbent material
•Call ER24 on 084 124.
•Follow the telephonic advice until an ambulance arrives.
