When summer heat and humidity kick in, so do the thunderstorms, and this is when electrical hazards during a storm can come into play. The National Weather Service estimates around 100,000 storms occur annually in the U.S. About 10% are severe and produce hail at least ¾-inch in diameter, winds of 58 mph or higher, or tornadoes. Thunderstorms can be damaging and deadly. Make sure to take precautions the next time you’re caught in a super summer storm.
The Dangers of Thunderstorms
Lightning is responsible for an average of 93 deaths and 300 injuries every year. Thunderstorms also cause several hundred million dollars in damage to property and forests. Flooding is the number one thunderstorm killer. Most flash floods happen at night and when people become trapped in automobiles. Straight-line winds, including downbursts and tornadoes, are responsible for most of the wind damage.
Preparing for a Storm
Properly prepare for a thunderstorm if one is imminent. Put together an emergency kit that includes water, flashlights, and radios. Pay attention to local weather reports and safety recommendations. Seek shelter if you hear thunder. If the power goes out, switch off lights, large electronics and appliances to prevent overloading circuits when it returns. Consider installing ground fault circuit interrupters in kitchens, bathrooms, and other areas that are near water. GFCIs sense electrical danger and will cut off power.
Safety During a Storm
If you get caught outside during a lightning storm, move to a low point and stay away from trees. Don’t hold onto metal items like golf clubs, bats or tools. Steer clear of metal fences, poles and sheds. Stay away from water and wet areas. If you are driving, pull off the road and stay in your vehicle. Don’t turn on the radio. Cell phones are safe if they’re not plugged in.
If you are indoors, stay away from windows and doors. Avoid contact with water and plumbing. If possible, unplug electronic equipment before the storm arrives. Make sure to bring your pets indoors.
What to Do After the Storm
Stay away from downed power lines and debris which may be hiding an electrical hazard. Move at least 10 feet away from a downed wire or anything touching it. If you are driving and come upon one, stay in your vehicle and call for help. Intersections where the traffic lights are out should be treated as a four-way stop.
Make sure all electric and gas services are turned off before entering a storm damaged room or building. Never turn off power at the breaker box if you must stand in water. Call your utility company. Don’t go into a flooded basement if water is covering electrical outlets or cords. Never use water-damaged electrical items until they are inspected by a qualified electrician.
The Scoop on Portable Generators
If you have a portable generator, here are some key safety tips you need to follow.
Follow all manufacturers’ recommendations. Never run it inside your house, garage or shed. Place the generator at least 20 feet from the house. Keep it dry and don’t run it in the rain. Only use extension cords meant for outdoor use that match the circuit breaker of the generator outlet. Never plug a generator directly into a home electrical outlet without an appropriate transfer switch. Call a licensed, qualified electrician for help.
