If you know someone collapsed and you suspect the cause to be electric shock, take the following actions:
Step 1

Turn the power off at the main.
If this is not possible, stand on dry
insulated material such as newspaper, books or rubber
malting.
Push the casualty away from the power source using nonconductive items such as the safety hook, broom or chair.
ONLY perform the above if it’s safe to do so. If it’s not
safe, call the EMERGENCY SERVICE 911 or someone
is familiar with live power.

movements, listen at the mouth for breath sounds and
feels for air on your check – look, listen and feel for 5
