Avoid using a corded phone

While it is not necessary to turn off your electricity at the breaker during a thunderstorm, it is important to take precautions to protect yourself and your devices. One crucial precaution is to avoid using a corded phone during a thunderstorm.

Corded phones, also known as landline phones, are directly connected to the electrical wiring of a building through their phone lines. This means that lightning can travel through the phone lines and into your home, posing a serious risk of electric shock. Even if you have a surge protector installed, it may not be enough to protect against a lightning strike, which can carry hundreds of thousands, or even millions, of volts of electricity.

If you need to make a phone call during a thunderstorm, it is much safer to use a mobile phone as long as it is not connected to a charging cord. Mobile phones are generally safer to use during thunderstorms because they are not physically connected to the electrical wiring of a building. However, it is still recommended to keep your phone use to a minimum during a storm, as even mobile phones can be affected by power surges or electromagnetic interference caused by lightning.

If you must use a phone during a thunderstorm, consider using a cordless phone instead of a corded one. Cordless phones use radio or digital technology to transmit calls, so they are not physically connected to the phone lines and do not pose the same risk of electric shock. Just be sure to keep the cordless phone base unit unplugged during the storm to protect it from power surges.

In addition to avoiding corded phones, there are several other precautions you should take during a thunderstorm.

Stay away from concrete and metal

During a thunderstorm, it is important to take precautions to ensure your safety. While thunder itself cannot hurt you, lightning can be dangerous, and it is crucial to understand the risks and follow safety guidelines. One such precaution is to stay away from concrete and metal objects. Here's why:

Concrete, particularly concrete walls and flooring, can contain rebar and wiring, which can conduct electricity. If lightning strikes a building with concrete walls or flooring, it can travel through the concrete and pose a risk of electric shock. This means that it is not advisable to lean against exterior concrete walls during a thunderstorm.

Metal is a well-known conductor of electricity, and lightning can travel through metal wires and bars. Therefore, it is crucial to avoid metal objects during a thunderstorm. This includes outdoor metal objects such as motorcycles, bicycles, golf clubs, fishing rods, prams, metal fencing, and railings. Even indoors, metal objects can be hazardous during a thunderstorm. Lightning can travel through metal pipes and wiring, so it is best to avoid taking a shower or bath, and refrain from washing your hands in a sink during a storm.

It is worth noting that you don't need to be directly struck by lightning for it to cause harm. If lightning strikes near a power line, the surge of electricity can travel through the power lines and into your home, potentially damaging electronic devices and even causing electrical fires. This is why it is generally recommended to unplug electronic devices and appliances during a thunderstorm.

By staying away from concrete and metal objects, you reduce the risk of electric shock and other potential hazards during a thunderstorm. Remember, if you hear thunder, you are within striking distance of lightning, so it is important to seek shelter in an enclosed building or a car with a hard-topped metal roof and closed windows.

Don't stand near windows

While it is important to take measures to protect your electrical devices and appliances during a thunderstorm by unplugging them or using surge protectors, it is equally crucial to prioritize your personal safety. One vital precaution is to avoid standing near windows during a thunderstorm.

Thunderstorms can present various hazards, and standing near a window can expose you to potential dangers. Here are some reasons why you should avoid standing near windows during a thunderstorm:

  • Lightning Risk: Windows, particularly those with metal frames or those that are the tallest in the vicinity, can attract lightning strikes. If lightning strikes near your window, the electricity can travel through the window frame and cause serious injuries or even death. By staying away from windows, you reduce the risk of being affected by lightning strikes or electrical surges that could enter your home through the window.
  • Falling Debris: Thunderstorms are often accompanied by strong winds, heavy rain, and hail. Standing near a window puts you at risk of being injured by flying debris, broken glass, or falling trees and branches. Strong winds can cause objects to be blown around, and you don't want to be in the line of fire if something is propelled through your window.
  • Secondary Surge Injuries: While you may be diligently unplugging your devices and appliances to protect them from power surges, your neighbors might not be as cautious. If a power surge occurs due to lightning, it can affect the electrical wiring in nearby buildings. This surge could potentially travel through the wiring and affect devices in their homes. If you are standing near a window, you could be at risk of injury from any secondary surges that might occur in neighboring residences.
  • Flash Flooding: Heavy rainfall during thunderstorms can lead to flash floods, especially in low-lying areas. If you're standing near a window, you might not be aware of the rising water levels outside until it's too late. It's important to monitor the situation and be prepared to move to higher ground if necessary.
  • Electromagnetic Interference: Lightning strikes generate intense electromagnetic fields. While these fields are typically harmless, being in close proximity to a lightning strike (such as standing near a window) can result in electromagnetic interference affecting electronic devices nearby. This could potentially damage sensitive electronics or data stored on them.

In summary, staying away from windows during a thunderstorm is a crucial safety precaution. By heeding this advice, you reduce the risk of lightning-related injuries, protect yourself from flying debris, safeguard against secondary power surges, stay vigilant about potential flash floods, and minimize the chances of electromagnetic interference affecting your electronic devices. Always prioritize your safety and well-being during severe weather events.

Follow the 30-30 rule if you're near a pool

While being outdoors during a thunderstorm is dangerous, swimming in indoor pools is generally considered safe. However, it is recommended to follow the 30-30 rule and stay inside for at least 30 minutes after the last thunder clap.

The 30-30 rule is a simple and effective way to gauge the distance of a thunderstorm and determine when it's safe to go outside. Here's how it works:

If you see lightning, start counting. If you can count up to 30 seconds before hearing the thunder, the thunderstorm is at least 6 miles away, and you are relatively safe. However, if the duration between the lightning and thunder is less than 30 seconds, the thunderstorm is within 6 miles, and you should seek shelter immediately.

Once the thunderstorm has passed, wait at least 30 minutes after the last thunder clap before going outside or resuming outdoor activities, such as swimming. This is because lightning can still strike even if it's not raining, and you don't want to take any chances.

It's important to remember that swimming in outdoor pools during a thunderstorm is not advisable. Lightning can strike the water, and since water is a good conductor of electricity, it can electrify the entire pool, posing a significant risk to swimmers. Always follow the guidelines provided by the pool management and lifeguards and prioritize your safety during thunderstorms.
