Do no walk through flowing water. Drowning is the number one cause of flood deaths, mostly during flash floods. Currently can be deceptive; six inches of moving water can knock you off your feet. If you walk in standing water, use a pole or stick to ensure the ground is still there.
Do not drive through a flooded area. More people drown in their cars than anywhere else. Don't drive around road barriers; the road or bridge may be washed out.
Stay away from power lines and electrical wires. The number two killer after drowning is electrocution. Electrical current can travel through water. Report downed power lines to your electric utility provider. Have you electricity turned off by the appropriate electric utility provider. Some appliances, such as television sets, keep electrical charges even after they have been unplugged. Don't use appliances or motors that have gotten wet unless they have been taken apart, cleaned, and dried.
Be alert for gas leaks. Use a flashlight to inspect for damage. Don't smoke or use candles, lanterns, or open flames unless you know the gas has been turned off and the area has been ventilated.
