First Aid is immediate assistance or treatment given before medical help arrives. For bleeding wounds, apply pressure until bleeding stops and bandage firmly. If a body part is severed, place it in a plastic bag and seek medical help. For burns, cool the area with water and loosely cover with cling film or clean dressing without wrapping tightly. Seek medical help for all burns. For electric shocks, switch off power at mains before touching the person and call for ambulance if not breathing after power is off.
