The first few minutes
Make the area safe and limit the water
If the main shutoff is within safe reach and you know how to use it, turn it off to slow the water coming into the property. Stay out of standing water near outlets, appliances or other electrical equipment, and never wade in to reach a breaker panel. If the area is unsafe, leave it and call from somewhere safe.
Stop using any fixture that is overflowing or backing up, and avoid contact with wastewater. Photos are useful for your records, but they are never worth stepping into a hazard for. Protecting people comes before moving belongings or starting cleanup.
