If you can hear thunder, you are close enough to the storm to be struck by lightning. Find shelter on the lowest floor of a sturdy building, away from open windows and doors, when a storm approaches. If you cannot get inside to shelter, squat low near the ground in an open area. Lying flat on the ground is not recommended, because it puts more of your body into contact with the ground, an excellent conductor of electricity from lightning. Turn off air conditioning.
Power surges from lightning can overload the compressor, resulting in a costly repair job.
Draw blinds and shades over windows. If windows break due to objects blown by the wind, the shades may prevent glass from shattering into your home. If you are in a mobile home or car during severe weather and conditions are right for a tornado, get out of the mobile home or car and find sturdy shelter elsewhere. People struck by lightning carry no electrical charge and can be handled safely. The injured person has received an electrical shock and may be burned.
