Blackout and power cuts

Stay safe, keep food and medicines safe, and avoid carbon monoxide when the power is off for hours or days.

Draft: written from the official sources below, awaiting human review.

Before

  • Keep a torch for every person, spare batteries and a charged power bank.
  • Store non-perishable food and water.
  • Fit carbon monoxide (CO) alarms with battery backup on every floor.
  • If someone relies on an electric medical device or refrigerated medicine, make a plan with their doctor now: how long can the medicine stay unrefrigerated, and what is the backup power?
  • Find out where local warm or cool spaces are during long outages.

During

  • Keep the fridge and freezer closed. A closed fridge keeps food cold for about 4 hours; a full freezer for about 48 hours.
  • Unplug appliances and electronics to protect them from a power surge when electricity returns.
  • Never heat your home with a gas cooker or oven. It can cause carbon monoxide poisoning, fire and burns.
  • If it is very hot or very cold, go to a place that still has power.

Generators: carbon monoxide kills

  • Use generators only outdoors, at least 6 metres (20 feet) from windows, doors and garages. Never indoors or in a garage.
  • CO has no colour and no smell. Working CO alarms save lives.
  • Keep the generator dry, use heavy-duty extension cables, and let it cool before refuelling.

After

  • When in doubt, throw it out. Bin food that was at 4 °C (40 °F) or warmer for 2 hours or more, or that smells, looks or feels wrong.
  • If the power was out for more than a day, throw away refrigerated medicines unless the label says otherwise, and ask your doctor or pharmacist for a new supply.
