How to check your service stack

Power outage checklist:

  • Remember, leave one light on to know when the power has been restored
  • Ensure all major appliances are turned off
  • Never use a barbecue indoors. Carbon monoxide emissions can cause asphyxiation
  • Turn off water to the clothes washer and dishwasher
  • A small bicycle pump can supply air to the fish tank
  • Keep an emergency kit with bottled water, flashlight and batteries, candles, holders and matches, battery-powered radio and alarm clock
  • Do not open the refrigerator or freezer door while the power is off. Most foods will stay frozen for at least 12 hours, refrigerated for 16.
  • If you will be away from home for more than three days during an extended winter power outage, turn your water supply off at the main shut-off valve to prevent pipes from freezing.

If you use a candle, here are some safety tips:

  • Use well ventilated holders that are sturdy and will not tip over
  • Keep burning candles away from materials that can catch fire (like curtains, decorations and clothing)
  • Keep burning candles out of reach of children and pets
  • Do not leave candles burning unattended
  • Extinguish all candles before you go to sleep
  • Battery operated candles are very popular, try and keep one on hand

When power is restored:

  • Check that the freezer and refrigerator are working and if any food needs immediate attention
  • Dairy products should be discarded after four to six hours.
  • Reset clocks, automatic timers and alarms
  • Plug in only the most essential appliances. If you wait 10 to 15 minutes before reconnecting, the system has time to stabilize
  • Return all emergency items to their usual place
