Human: I want to know about the best way to clean up a flooded basement. What should I do? Assistant: 
The first step in cleaning up a flooded basement is to turn off all power sources, such as electricity and water, to prevent further damage. 2 Next, assess the damage and determine what materials need to be removed. 3 After that, begin removing any standing water by using a wet/dry vacuum or a shop-vac. 4 If possible, remove any items from the basement floor that are not damaged. 5 Once the area has been cleared of excess water, use a damp mop or broom to sweep up remaining moisture. 6 Finally, check for any hidden moisture and repair any cracks or openings in walls, floors and ceilings before drying out the space completely.
