Know How To Stay Safe After Storms
Severe thunderstorms, tornadoes, hurricanes, and flooding can leave more than damage in their wake — they can leave hidden dangers as well. In some cases, more lives are lost after the storm than from the storm itself.
“When you’re dealing with storm cleanup or flood-damaged property, the prospect of an electrical accident is probably not top of mind,” says Safe Electricity’s Molly Hall. “But it’s the first thing you should think of before you go outside, step foot into a flooded area, or enter a storm-damaged building.”
When outside, stay away from downed power lines and be alert to the possibility that tree limbs or debris may hide an electrical hazard. Treat all downed or hanging power lines as if they are energized. Lines do not have to be arcing or sparking to be live. Warn others to stay away, and contact your cooperative.
Do not touch downed power lines, and do not touch objects or puddles of water in contact with those lines. There is no way to know if they are energized. Encountering these objects can be as hazardous as coming into contact with a downed power line itself.
As part of its “Teach Learn Care TLC” campaign, Safe Electricity urges parents and other caregivers to make sure children are aware of these hazards as well.
Safe Electricity offers other precautions following storms:
- If you are driving and come upon a downed power line, stay in your vehicle, warn others to stay away, and contact emergency personnel or your cooperative. Never drive over a downed line, as it could pull down poles and other items along its path.
- Be alert at intersections where traffic lights may be out. Stop at all railroad crossings, and treat road intersections with traffic signals as four-way stops before proceeding with caution.
- Before re-entering storm-damaged buildings or rooms, be sure all electric and gas services are turned off. Never attempt to turn off power at the breaker box if you must stand in water to do so. If you cannot reach your breaker box safely, call your cooperative to shut off power at the meter.
- Never step into a flooded basement or other area if water is covering electrical outlets, appliances, or cords. Be alert to any electrical equipment that could be energized and in contact with water. Never touch electrical appliances, cords, or wires while you are wet or standing in water.
- Keep electric tools and equipment at least 10 feet away from wet surfaces. Do not use electric yard tools if it is raining or the ground is wet.
- Electric motors in appliances that have been drenched or submerged should be thoroughly cleaned and reconditioned before they are put back into service. It may be necessary to replace them. Do not use any water-damaged appliance until a professional has checked it out.
- If, after a storm or disaster, the power to your home is out for a prolonged period, know important safety rules, such as never using a charcoal or gas grill to cook inside.
- If you use a portable generator, be sure a transfer safety switch has been installed, or connect appliances directly to the generator. This prevents electricity from traveling back through the home to power lines — what is known as “backfeed.” Backfeed creates danger for anyone near lines, particularly crews working to restore power.
Destructive Illinois tornado claims lives
Residents of Harrisburg and surrounding communities continue to piece their lives back together after a devastating tornado tore through the area in the early morning hours of Feb. 29.
Seven people died as a result of the storm, many others were injured and multiples homes destroyed along with businesses and landmark buildings.
The tornado’s Enhanced Fujita Scale rating of EF-4 affected areas of Southeastern Illinois Electric Cooperative’s territory outside the Harrisburg area. Around 4,200 SIEC members lost power, but it was restored within 24 hours according to personnel at SIEC.
An employee at SIEC and his wife were displaced from their home as a result of the tornado. As Greg and Lisa Thomas were seeking shelter in the lower level of the home, the roof was torn from the structure. Neither was injured.
Saint Joseph’s Catholic Church in the town of Ridgway was also dismantled by the storm. A number of SIEC employees attend the large church and are involved in cleanup.
Electrical safety during and after storms
Frequently Asked Questions
Severe storms and natural disasters can cause a variety of electrical safety hazards in and around our homes. Lightning, downed power lines, and floods are just a few of the serious safety concerns associated with storms. Unfortunately, many of these electrical safety hazards remain long after the storm itself has passed.
To help protect you from storm-related electrical hazards, the Electrical Safety Foundation International (ESFI) and your cooperative are providing answers to common storm safety questions about:
- Power Lines
- Flooded Areas
- Wet Electrical Equipment
- Portable Generators
- Post-Evacuation Procedures
What should I do if I am caught outside during a lightning storm?
- Move to a low point. Lightning hits the tallest available object, so get down low in a crouched position if you are in an exposed area.
- Stay away from trees.
- Avoid metal. Don’t hold onto metal items like bats, golf clubs, fishing rods, tennis rackets, or tools. Stay away from metal sheds, clotheslines, poles, and fences.
- Stay away from water, including pools, lakes, puddles, and anything damp—like grass.
- Don’t stand close to other people. Spread out.
Is there any sort of warning before lightning strikes?
Not necessarily, but sometimes. If you feel a tingling sensation or your hair stands on end, lightning may be about to strike. Do not lie down. Instead, crouch down, tuck your head, and cover your ears.
What should I do if I encounter a lightning storm while driving in my car?
Slow down and use extra caution. If possible, pull off the road into a safe area.
Am I safer in or out of my car?
Do not leave your vehicle during a thunderstorm. A vehicle is considered safe during a thunderstorm if it is fully enclosed with a metal top such as a hard-topped car, minivan, bus, truck, etc. While inside a safe vehicle do not use electronic devices, such as radio communications.
The storm is still raging outside. Are we safe from lightning if we stay inside the house?
- Follow these indoor lightning safety tips to help keep your family safe inside while it’s storming outside:
- To avoid lightning strikes, stay away from windows and doors.
- If possible, unplug electronic equipment before the storm arrives. Avoid contact with electrical equipment and cords during storms.
- Avoid contact with water and plumbing, including sinks, baths and faucets.
Can I talk on the telephone during an electrical storm?
Use corded telephones only for emergencies. You can use cordless or cellular phones.
I have an outside dog. Is it okay to leave him out there during a lightning storm?
Doghouses are not lightning-safe, and chained animals can easily become victims of lightning strikes. You should bring your pets inside to protect them.
What should I do if I encounter a downed power line?
If you see a downed power line, move at least 10 feet away from the line and anything touching it. The human body is a ready conductor of electricity.
The proper way to move away from the line is to shuffle away with small steps, keeping your feet together and on the ground at all times. This will minimize the potential for a strong electric shock. Electricity wants to move from a high voltage zone to a low voltage zone—and it could do that through your body.
What can I do to help someone who has come in contact with a downed power line?
If you see someone who is in direct or indirect contact with the downed line, do not touch the person. You could become the next victim. Call 911 instead.
Can I use something that is not metal to try to move a downed power line myself?
Do not attempt to move a downed power line or anything in contact with the line by using another object such as a broom or stick. Even non-conductive materials like wood or cloth, if slightly wet, can conduct electricity and then electrocute you.
What should I do if I see a downed power line in the street while I am driving my car?
Do not drive over downed power lines.
What if a power line comes down onto my car or I didn’t see it until I’ve driven into it?
If you are in your car and it is in contact with the downed line, stay in your car. Tell others to stay away from your vehicle.
If you must leave your car because it’s on fire, jump out of the vehicle with both feet together and avoid contact with the live car and the ground at the same time. This way you avoid being the path of electricity from the car to the earth. Shuffle away from the car.
Is a downed power line still dangerous if it has come down in water, like a pool or pond?
Water is a good conductor of electricity. Any amount of water—even a puddle—could become energized. Be careful not to touch water—or anything in contact with the water—near where there is a downed power line.
My basement has flooded and there is standing water. Is it safe to go down there?
Use extreme care when stepping into flooded areas. Submerged outlets or electrical cords can energize water, posing a lethal trap.
My washer, dryer, and a few other appliances got really wet during the flood. Can I start using them again after they dry out?
Do not use electrical appliances that have been wet until they have been examined by a qualified service repair dealer. Electrical equipment exposed to water can be extremely dangerous if re-energized without proper reconditioning or replacement.
Does a flood affect my home’s electrical system, too, or just the appliances?
Electrical items, such as circuit breakers, fuses, ground fault circuit interrupters (GFCIs), receptacles, plugs, and switches, can malfunction when water and silt get inside. Discard them if they have been submerged. Have a licensed, qualified professional replace them.
Does it make a difference if the flood was caused by storm water or by a leaky water pipe?
Ocean water and salt spray can be particularly damaging to electrical equipment due to the corrosive and conductive nature of the salt water residue. Damage to electrical equipment can also result from exposure to flood waters contaminated with chemicals, sewage, oil, and other debris.
No matter what caused the flood, electrical appliances should be examined by a qualified service repair dealer before being re-energized, and electrical items that were submerged should be discarded and replaced by a licensed, qualified professional.
Can flooded outside areas be dangerous too?
Yes — downed power lines or submerged outlets from adjacent homes could energize the water. Use extreme caution when entering any flooded area.
Wet Electrical Equipment
My home wasn’t flooded, but some electrical appliances have gotten wet. Do the same safety rules listed above apply to my situation?
Yes — they still apply. Do not use electrical appliances that have been wet until they have been examined by a qualified service repair dealer. Water can damage the motors in electrical appliances, such as furnaces, freezers, refrigerators, washing machines, and dryers.
Where can I find out more about what should be done with water damaged electrical equipment?
The National Electrical Manufacturers Association (NEMA) has produced a brochure, Guidelines for Handling Water Damaged Electrical Equipment, for use by suppliers, installers, inspectors, and users of electrical products to provide advice on the safe handling of electrical equipment that has been exposed to water. The NEMA brochure may be downloaded free of charge at: www.nema.org/stds/water-damaged.cfm.
I bought a new generator so that I’d be prepared for the next power outage. Is there anything special I should know about installing it?
ESFI strongly recommends that a licensed electrician install home generators to ensure they meet all local electrical codes.
Also, make sure your generator is properly grounded in accordance with the manufacturer’s instructions.
Can’t I just plug my generator directly into one of my home’s outlets?
Do not connect generators directly to the household wiring unless an appropriate transfer switch has been installed by a licensed, qualified electrician.
What could happen if I don’t have a transfer switch installed?
Without the proper transfer switch, power provided by the generator can “backfeed” along the power lines, creating a significant electrocution hazard for anyone coming in contact with the lines, including lineworkers making necessary repairs.
I’ve heard that generators should be kept dry. Can I run it in my garage to protect it from the rain?
Never operate a generator inside your home or in any other enclosed—or even partially enclosed — area. Generators very quickly produce carbon monoxide, which can easily enter your home.
Place the generator on a dry surface under an open, canopy-like structure. Do not operate the generator in wet conditions or where there is standing water.
Can’t I just open the garage door to provide ventilation for the carbon monoxide?
Opening windows or doors or using fans does not provide adequate ventilation to prevent the build-up of carbon monoxide. Generators must be located outside a safe distance away from your home’s windows, doors, and vents, through which carbon monoxide can enter your home.
How far away from the house is a safe distance?
Preliminary research from the Centers for Disease Control and Prevention (CDC) and the National Institute of Standards and Technology (NIST) indicates that even 15 feet from the home is too close to operate a generator safely.
Remember your neighbors, too. Keep your generator a safe distance away from their homes as well.
What exactly is carbon monoxide?
Carbon monoxide (CO) is a poisonous gas that is created when common fuels such as natural gas, oil, wood, or coal burn incompletely. This odorless, colorless, tasteless gas is often called the “silent killer” because it is virtually undetectable without the use of detection technology like a CO alarm. Extremely high levels of carbon monoxide can be fatal within minutes.
How big a problem is carbon monoxide associated with the use of generators?
From 1999-2009, 542 carbon monoxide deaths associated with portable generators were reported to the Consumer Product Safety Commission (CPSC).
More than 80 percent of carbon monoxide deaths related to portable generators occurred in the home, often resulting from operation of a portable generator within the living space of the home, including the basement, closets, and doorways.
What are the symptoms of carbon monoxide poisoning?
Symptoms of carbon monoxide poisoning may include fatigue, shortness of breath, drowsiness, headache, and nausea. Get to fresh air right away if you feel dizzy or weak while running your generator.
Is there anything else I should do to protect my family from carbon monoxide produced by my generator?
Make sure that there is at least one battery-operated or battery-backup carbon monoxide alarm in your home. Test it before using your generator.
Is it safe for my children to play in the area around the generator?
No. Keep children away from portable generators at all times. Also be sure to store generator fuel out of reach of children.
How many appliances can I plug into my generator at one time? Can I use it for my window air conditioner and my refrigerator at the same time?
The capacity of generators varies. Follow the manufacturer’s instruction carefully. Do not overload the generator.
My generator is powering my sump pump, but it is going to need more fuel soon. Can I refuel it while it’s running so I don’t have to turn off the sump pump?
Unplug all appliances from the generator before shutting it down. Turn the generator off and let it cool down before refueling. Refueling the generator while it is running is a significant fire hazard.
The storm is finally over. Can I go home now?
First and foremost, do NOT return home until instructed by the appropriate local authorities. Once they give the go-ahead:
- Return home during daylight hours, especially if power has not been restored.
- If you smell gas, leave the premises and notify emergency authorities immediately. Do not turn on lights, light matches, or engage in any activity that could create a spark.
I’ve been told by my local authorities that I can return home now, but could there still be electrical dangers in and around my home?
Yes. Even if you have been authorized to return home, you should still take precautions to protect yourself from electrical hazards posed by downed power lines, flooded areas, and water-damaged appliances and electrical equipment.
