Collect supplies and air out your home

Dispose of household items

Air out your home

Things should be dry within 48 hours or 2 days so mould doesn’t grow.
Food and Water Safety
- If your water comes from a well, or your drinking water is unsafe to drink, boil well water for at least one minute before using or use bottled water for drinking, infant formula, making ice, washing fruits and vegetables, brushing teeth, etc.
- Once flooding has receded you may begin to disinfect your well. Refer to our fact sheet “Well Disinfection Procedure.”
- Throw away any open food containers that came into contact with floodwater.
- Sealed and canned goods may be kept if the outside containers are washed and disinfected.
- If your fridge has been without power for over 4-6 hours, throw everything away.
- If your chest freezer is full, food will remain frozen for up to 48 hours after losing power, just keep the door closed.
- Remember: if in doubt, throw it out!
- Do not use flooded appliances and devices
- Before working on any electrical device, disconnect all power at the services panel by turning the main switch to the “off” position.
- If floodwater rose above outlets, power cords, or is near the service panel, contact your electrical company to turn off your power.
- If your power is turned off call a licensed electrician to determine what needs to be replaced.
- Do not plug in any electrical appliances that got wet until they have been checked by an electrician.
