Place one electrode pad on the victim's upper right chest and one on the lower left side under the victim's left breast. Yes, it is safe to use AEDs in all weather conditions. However, if at all possible, move to shelter and keep the victim protected from inclement weather. In wet weather, be sure to wipe the victim's chest dry before placing the electrode pads. You or someone else could get shocked.
Alcohol is flammable.
Movement may affect the analysis. Move victims away from puddles of water or swimming pools or out of the rain before defibrillating. Conductive surfaces, such as sheet metal or metal bleachers, may transfer the shock to others. AEDs do not have the capability to adjust to the low-energy settings needed for infants and children. Local protocols may differ on this and should be followed.
