Persons hit by lightning do not carry an electrical charge; they can be touched without danger. However, victims may suffer from burns and shock and must receive medical care immediately. If you happen upon a person who has been struck by lightning, request medical assistance immediately and, if the person has stopped breathing, administer mouth-to-mouth or cardio-pulmonary resuscitation (CPR).
To consult maps about the most recent lightning activity, go to the website Canadian Lightning Danger Map - Canada.
- Avoid driving on flooded roads and passing under road bridges.
- If you stop your car, stay inside.
- Keep your gas tank full and have a reserve supply of window-washing fluid and antifreeze.
