There are some safety concerns when your basement is flooded.
1)Be sure all electricity to the house is off. Before walking across the basement floor - check and makes sure no power or appliance is on.
2)It is important to remove the water in the basement in stages. Water removed too fast from a basement may cause the foundation walls to collapse.
3) Make sure that the water you are pumping out of the basement is directed in a way that does not cause a safety hazard. For example, do not allow ground water to be pump into the street in winter months as it could freeze and cause a dangerous situation.
