Lightning And Windows: A Dangerous Combination?

While it is rare for lightning to strike through a window, it is possible. Lightning can enter a building in three main ways: a direct strike, through pipes or wires, or through the ground. While glass does not conduct electricity well, lightning can shatter or explode windows, and then enter the building. Therefore, it is recommended to stay away from windows during a thunderstorm, as they may shatter and cause injury.

Lightning can enter a building through windows, wires, or pipes

Lightning can enter a building in three main ways: a direct strike, through wires or pipes, or through the ground.

Lightning can directly strike a window, causing the glass to shatter or explode due to the heat and speed of the lightning bolt. While windows are unlikely to conduct electricity, the lightning bolt can still enter the building through the window frame or by shattering the glass. Therefore, it is essential to stay away from windows and close them during a thunderstorm to minimize the risk of injury from shattered glass or a potential lightning strike.

Another way lightning can enter a building is through wires or pipes. If lightning strikes utility infrastructure, it can travel through those pipes or wires and enter the building. This includes electrical wiring, phone lines, TV cables, and plumbing. As lightning seeks the ground, it is crucial to avoid using electronic devices connected to power outlets and stay away from water pipes during a thunderstorm.

Lastly, lightning can enter a building through the ground, especially if the structure has a concrete foundation. Lightning can travel through the metal wires or bars in concrete walls or flooring, posing a risk of electric shock to anyone in contact with the concrete surface.

To stay safe during a thunderstorm, it is recommended to stay away from windows, close and fasten windows, and avoid using corded phones, electronic devices connected to power sources, and water pipes. Creating a safety plan and practicing drills with your family can also help ensure everyone knows how to stay safe during a thunderstorm.

Glass windows are more likely to shatter or explode than allow lightning to pass through

While it is rare for lightning to strike through a window, it is not impossible. However, glass windows are more likely to shatter or explode than allow lightning to pass through. This is because glass is a poor conductor of electricity. When lightning strikes a window, the glass shatters or explodes due to the electrical current, which cannot be safely conducted through the window.

Glass is an excellent insulator, which is why it is commonly used in windows to protect against the elements. However, this insulating property also means that glass cannot safely conduct electricity. When lightning strikes, the electrical current has nowhere to go, and the window shatters as a result. This is a significant concern during storms, as broken windows can cause damage and injury.

It is essential to stay away from windows during a thunderstorm, as lightning can strike nearby objects and cause them to hit the window, leading to dangerous shards of glass. In addition, the thunder that accompanies lightning can be intense enough to shatter windows. Closing and fastening windows before a storm is crucial, as open windows increase the likelihood of lightning striking an object inside the house.

While the chances of being struck by lightning through a closed window are slim, it is still possible. Once lightning enters a structure, it can travel through electrical, phone, plumbing, and radio/television systems. Therefore, it is crucial to stay away from conductive materials, such as metal or water pipes, during a thunderstorm.

To stay safe during a thunderstorm, it is recommended to keep a safe distance from windows, close the blinds, and stay away from conductive materials. By following these precautions, you can reduce the risk of injury from lightning and shattered glass.

Lightning can enter a building through the ground

While windows can be struck by lightning, it is very unlikely that lightning will travel directly through them. This is because windows are typically made of glass, which is a poor conductor of electricity. As such, glass tends to explode or shatter when struck by lightning.

To stay safe during a lightning storm, it is important to stay away from windows, as well as concrete floors and walls. Keep windows and doors shut and avoid touching water or plumbing fixtures. Unplug appliances if possible and stay away from electrical appliances and cords.

Lightning can travel through electrical, phone, plumbing, and radio/television systems

Lightning can cause significant harm to electrical systems, and it can enter a building in three main ways: direct strikes, through pipes or wires, and through the ground. It can travel through electrical systems, radio and television reception systems, and any metal wires or bars in concrete walls or flooring. Therefore, it is advised to avoid using or touching any electrical equipment during a thunderstorm, including computers, laptops, game systems, washers, dryers, or stoves.

Lightning can also travel through phone systems, but it is important to distinguish between corded phones and mobile phones. Corded phones, also known as fixed-line or copper wire phones, should be avoided during thunderstorms as lightning can travel through their wires. However, mobile phones or fibre optic cables are considered safe to use during storms as they are low-power devices and do not have characteristics that would make them attractive to lightning strikes.

Plumbing systems, particularly those made of metal, are also susceptible to lightning strikes. Lightning can travel through metal plumbing systems and pipes, potentially electrocuting individuals who come into contact with faucets or showerheads. Plastic pipes, such as PVC, offer some protection against electrocution, but the risk of lightning travelling through plumbing is not completely eliminated. This is because lightning can also travel through water, so it is recommended to avoid any contact with plumbing and running water during a storm.

Additionally, lightning can enter a building through radio/television systems. It can induce currents in nearby metal objects or electrical circuits, potentially overloading and damaging them. Therefore, it is advised to stay away from electronic devices and appliances during a thunderstorm to minimise the risk of lightning-related harm.

Metal objects, concrete walls, and water are conductors of electricity

It is important to understand that lightning can indeed enter a building and harm those inside. This can happen in three main ways. Firstly, lightning can directly strike a building and enter through windows. Secondly, it can enter through pipes or wires if the utility infrastructure is struck. And thirdly, lightning can enter through the ground. Therefore, it is important to be vigilant and take precautions during a thunderstorm, even when indoors.

Concrete, although a less effective conductor than metal, can also transmit electricity. Its ability to conduct electricity depends on its composition and moisture content. Concrete contains aggregates, cement, and water, and the conductivity of each block of concrete can vary. Aggregates like black steel slag, for example, increase the conductivity of concrete. The wetness of concrete also plays a role; wet concrete is more conductive than dry concrete. Therefore, it is important to be cautious around wet concrete and to keep exposed electrical wires away from it.

Water is also a well-known conductor of electricity. Lightning can travel through water, which is why it is important to avoid plumbing and pipes during a thunderstorm. Lightning can enter a building through pipes and conduct electricity through the water inside. This is why activities such as washing dishes, taking a shower, or bathing during a thunderstorm are not recommended.
