Most individuals are familiar with the common severe weather saying: “When thunder roars, go indoors!” Currently, Canada is experiencing an unusually active thunderstorm season, and the Canada Safety Council (CSC) estimates that lightning flashes occur once every three seconds during the summer months. While it is rare for lightning to make direct contact with humans, it is important to take thunderstorms seriously and not take unnecessary risks.
Thunderstorms can be deceiving in terms of their distance. The CSC warns that lightning can strike several kilometers away from its source. In other words, the danger window for lightning storms is longer than most people anticipate. Just because lightning sounds far-off doesn’t mean you are out of harm’s way. If you can hear thunder, you are within striking distance of lightning.
Here are some surprising risks associated with thunderstorms and ways to stay safe when lightning is in the forecast:
1. Find shelter indoors: If a thunderstorm is imminent, it is advised to move indoors immediately. However, not all indoor activities are equally safe. The CDC estimates that approximately one-third of all lightning strike injuries occur to people inside. The CSC advises avoiding activities such as bathing, showering, doing laundry, or using water for chores or cooking during a storm. Lightning can strike plumbing systems and water can conduct electricity.
2. Stay away from windows: While being indoors is the safest option during a thunderstorm, it is important to put as many walls as possible between you and the outdoors. Avoid standing in front of windows, as flying debris can shatter glass. Thunder can produce shockwaves capable of breaking glass. Doors and fireplaces should also be avoided. The best option is to stay away from the exterior of the home in an interior room or basement.
3. Beware of exposed areas: If caught outside during a storm and unable to find shelter, it is crucial not to lie down on the ground. Spreading out your body increases the chances of a lightning strike, as electrical currents can travel along the top of the ground. If in an open field, crouch down as low as possible with your hands on your knees. Stay away from metal structures such as fences or flagpoles.
4. Biking and motorcycles are risky: While motorists can stay inside their cars with the windows and doors shut during a thunderstorm, the same does not apply to individuals on bikes, motorcycles, ATVs, or golf carts. Rubber tires on these vehicles will not provide protection, and the exposed metal frames pose a risk.
5. Avoid trees during thunderstorms: Seeking shelter under a tree is extremely dangerous during lightning storms. It is the second-leading cause of lightning deaths, following deaths around water. If in a forest, it is better to find a grouping of lower trees to ride out the storm.
6. Additional scenarios: If on a boat without a cabin during a thunderstorm, drop the anchor and make yourself as small as possible by crouching down with hands on your knees. If caught outside in a large group, it is best to spread out to reduce the number of injuries if lightning strikes the ground.
Remember to follow these safety precautions during thunderstorms to minimize the risk of lightning-related accidents and injuries.
