Be aware that hazards exist above (low-hanging electrical lines) and below (mailboxes, fences, gas and parking meters, etc.) the boat.
Ensure that utilities are secured in the area of engagement prior to in-water rescue activities.
Use a pole or staff to probe ahead when wading in non-moving floodwaters to make sure there are no open manholes or other traps.
Never underestimate the power of moving water.
Only 18 to 24 inches will lift and move a vehicle.
Underwater currents can be very deceiving, especially if debris is in the water or visibility is poor.
Do not drive or allow anyone else to drive across a flooded roadway. During floods, the #1 reason for fatalities is driving across a flooded roadway.
Prepare for night operations. Floods do not care about what time of day it is.
Use reflective tape on helmets.
Issue light sticks and portable lights with extra batteries to all personnel.
Maintain radio contact with all personnel. Maintain par levels so that you always are able to meet all demands.
Handle victims properly.
Always place rescued victims in a proper PFD (life jacket) prior to moving them.
Consider sheltering them in place and then establishing safe havens only after consulting the forecast and your rescue capabilities.
Mark buildings and vehicles that have been searched for victims. Using a marking system that indicates they were already searched eliminates the potential for a second team wasting valuable time during a disaster response.
