Once a thunderstorm is detected, turn off electrical appliances, close doors and windows and, if possible, stay indoors during the storm. You can read more about forecasting in our previous blog post How to prepare for thunderstorms.
Despite advance preparations, thunderstorm damage can still occur. In this blog post, we explain what to do during a power outage and what to do after a power outage and thunderstorm.
Oops, there was a thunderclap and the house went dark!
The thunder roars, lightning flashes and the lights go out at home while the appliances stop. The thunderstorm has caused a power cut. At this point at the latest, it's important to turn off your home's lights, electrical appliances and unplug electrical cords from the wall. In particular, it is advisable to unplug TVs, computers, appliances and extension cords from the wall. If lightning strikes the power grid, it can cause a surge that can damage sensitive electrical equipment. There is also a risk of fire.
It is also important to switch off the equipment because the fuse system can overload after the power comes back on. Simultaneous start-up of several appliances after a power failure can place an additional load on the fuse board, which can damage it. It is therefore advisable to be cautious about starting equipment at the same time and, if necessary, to stagger the starting of equipment, especially if the power outage has lasted for a long time.
Most of today's buildings are equipped with effective protection systems to help prevent the effects of overvoltages. While these protections are commonplace today, you can never be too careful in the face of the elements. Especially for older buildings, extra caution is recommended during thunderstorms.
Because of the above, it is advisable to unplug electrical appliances when you leave the house for a longer period of time. You never really know how close a thunderstorm will come and how much damage it may cause.
After the storm observation tour
After severe thunderstorms, it's a good idea to do a round of checks both indoors and outdoors. We've put together a little checklist to help you identify the most common types of damage. However, it's worth bearing in mind that thunderstorms are a force of nature that can cause unexpected damage. Always remember to keep safety a priority when you're outdoors after a storm.
- Keep an eye on your surroundings, especially if there are power lines or power lines near your home. If you spot downed power lines, take extra care. Power lines in the ground are extremely dangerous and you should stay at least 20 metres away from them. Never touch power lines or attempt to move or repair them yourself. Also, if you notice trees or tree branches falling on power lines, be careful. Do not try to remove them yourself, as this could pose a risk of electric shock. If the situation looks dangerous, call 112 or the electricity company. 24 Center will help with any necessary repairs.
- Inspect the condition of buildings. Carefully check roof structures, chimneys and windows for possible damage. Pay particular attention to any cracks, loose parts or other signs of storm damage. If you find serious damage, do not go inside the building, but call in a professional to thoroughly inspect the building and make the necessary repairs.
- Go through your rainwater systems and check their condition. If necessary, clean them thoroughly. Make sure gutters, downspouts and other parts are free of debris and leaves that can block the normal flow of water. Rainwater systems should be checked regularly to ensure they are not blocked in the event of a thunderstorm.
- Check electrical appliances, especially the fridge and freezer, and the condition of the sockets. It is important to check their condition after the storm, as a damaged appliance or power supply can cause a fire. If your appliance won't start, makes a strange noise or smells burnt, stop using it and contact a repairman. Damage to the electrical network and equipment is the responsibility of professionals, so do not attempt to repair it yourself. 24 Center has a network of electrical repair professionals.
- If you discover water damage, act quickly and efficiently. Immediately turn off the main water supply to stop the flow of water. Then block or contain the leak with temporary means such as towels or other suitable barriers to prevent further damage. The most important thing is to minimise the spread of water and prevent it from entering other spaces or structures. 24 Center's network of water damage assistance is available.
