Lightning - Emergency Preparedness


When Thunder Roars, Get Indoors

If you can hear thunder, you are within striking distance of lightning. Take shelter immediately. Each year lightning kills approximately 10 Canadians and injures approximately 100 to 150 others.

If you are outside

  • If caught in the open, do not lie flat but crouch in the leap frog position and lower your head; you do not want to be the tallest object in the area.
  • Take shelter in a building or depressed area such as a dry ditch or a culvert but never under a tree.
  • Do not ride bicycles, motorcycles or golf carts, or use metal shovels or golf clubs as they conduct electricity.
  • If swimming or in a boat, get back to shore immediately.
  • If you are in a car, stay there but pull away from trees which could fall on you.

If you are inside:

  • If indoors, stay there but away from windows, doors, fireplaces, radiators, stoves, sinks, bathtubs, appliances, metal pipes.
  • Telephones (you can use a cellular telephone) and other materials, which conduct electricity.
  • Unplug radios and televisions and use battery or crank powered radio instead.
  • Do not go out to rescue the laundry as the clothesline conducts electricity.

When disaster strikes

  • Remain calm. Co-ordinated emergency services are responding.
  • Check for updates.
    • Halton Region’s Enhanced Community Emergency Notification Service (eCNS) is an emergency telephone notification service. It will be used in the event of a major disaster or catastrophe to communicate updates about emergency conditions, and other vital information, in addition to what you’ll receive from other sources.
    • Check our websites for updates about emergency conditions, what to do, where to go or other information you should know.
    • You may also receive information from television, radio and other sources, including door-to-door notification.
  • Help family members and neighbours.
  • Don’t forget your pets!
