Electrical contact on a construction site can cause cardiac arrest, severe burns, and death within seconds. A fast, correct response can save a life. Every operative must know how to respond safely without becoming a casualty themselves. This talk covers the emergency actions to take when someone suffers an electrical contact injury.
Key Hazards
Electrocution causing cardiac arrest or fatal burns
Rescuer becoming a secondary casualty from live contact
Delayed isolation allowing continued electrical exposure
Burns and blast injuries from arc flash events
Control Measures
Never touch a casualty who may still be in contact with a live electrical source.
Isolate the electrical supply at the nearest distribution board or isolator before approaching.
Call 999 immediately and request an ambulance, stating it is an electrical injury.
Ensure only competent persons carry out emergency electrical isolation procedures.
Administer CPR if the casualty is not breathing, following first aid training protocols.
Do not move the casualty unless they are in immediate further danger.
Keep bystanders well clear of the area until the supply is confirmed isolated.
Report the incident to the site manager and complete an accident report immediately.
Preserve the scene for investigation by the HSE if required.
