At Heightsafe Systems a properly installed lightning protection system, will not only protect the structure of a property, it will protect your people and your assets, so don’t be caught by a ‘bolt from the blue’, contact one of our Specialist Lightning Protection Consultants to discuss design, installation and maintenance. The well-known saying that ‘lightning doesn’t strike twice’ is not a complete fallacy, and the fact that global warming is something we all need to be considering, and what we can do to avoid the devastating consequences, needs to be fully considered and acted upon.To put this to test lets look at the Empire State Building in New York. Strikes of 49 in a single day have been recorded, and the building is said to be hit about 100 times every year. The testimony to a fully functional, crucial and maintained lightning protection system is that any damage has been minimal, and iconic building remains the same as it has for years.
Lightning is caused as a result of high voltage currents, its unpredictable and can strike during any season of the year. We have all noticed the increase in storm clouds and extreme weather conditions, making lightning strikes a high risk to property, people and our valued assets.
We would assume that lightning will always strike the top of the tallest object in its path, but it is as possible for lightning to strike very close to the base, and can cause damage not only to that object but to anything nearby.
Did you know that approximately 350,000 lightning strikes hit the ground in the UK each year, with a minimum of 25% causing severe damage, and that the proximity to water increases the risk of taking a strike.
Lightning strikes may appears a continuous force, but are only really a series of shorts bursts, and typically are about 40m in length, but can span anywhere between 10 – 120 metres in length, followed by 4 – 5 or many more strokes, but each carries hundreds to thousands of amps.
In large and heavy thunderstorms the total energy generated is said to be enough to power the whole of the UK for 20 minutes.
