Turn the power off!
Call 911.
NEVER touch the victim directly until the power is off.
If you do not have access to the power shut-off, attempt to remove the victim from the electrical sources in the following way:
Use a dry board, a broom handle, a rubber shoe, clothing, or other available non-conductive material to free the victim from electrical contact. Protect yourself with dry insulating material such as rolled up clothing, a wooden broomstick, etc.
Do not touch the victim until the source of electricity has been removed.
After the victim has been removed from the electrical source, determine whether the person is breathing.
If the person is not breathing, call 911 immediately. Use a method of artificial respiration.
The best choice is to phone 911 or the Poison Control Centre immediately.
