Lightning Protection Systems

Many children have a natural fear of thunder; let’s face it, it can be quite scary. As we get older we learn about the cause of thunder and how destructive lightning really can be. Lessons that the people at the lightning protection system team at Churchill Specialist Contracting Ltd know all about. The harm that lightning can cause to people is very well known, we have all heard the horror stories; organ failure, blindness, deafness, neural damage, it even causes death in one third of cases. Builds and other structures are not immune to similar damage, and as in the case of human beings it can be prevented.

As health and safety issues become increasingly common in the work place, it is only right that companies follow OHSAS guidelines to ensure not only the well being of their employees, but also take a vested interest in the well being of their property and assets. Lightning can not only cause massive damage to the exterior of a build, it can wreak havoc with internal electrical systems. Computers and data storage devices can be destroyed, losing weeks, months or even years of important records and information which in itself can cost millions to replace.

It is important to understand the magnitude of the energy unleashed by lightning, often exceeding 100 million volts and 40’000 amperes. This power can create huge amounts of heat in water saturated, porous materials used in the construction of buildings, causing them to explode as the water content is flash boiled. The solution: to provide a low-resistance path for the lightning circuit. Churchill Specialist Contracting Ltd is staffed by time served and experienced engineers who are highly skilled in lightning protection and earthing systems, from design and testing to installation. They also offer an alternative to the conventional Faraday cage type installation, the Helita “Pulsar” ESE system of lightning protection that conforms to the requirements of a European code, the French code of practice NFC17-102. 1995.

The Impact of Lightning Strikes on Businesses

Lightning is said to strike the ground around 8 million times a day and the impact that this can have on businesses can be very severe.

According to a survey carried out by a German insurance company, lightning accounts for 27.4% of damages to electronic equipment. Studies carried out by French insurance company AXA have also concluded that after a fire, one out of every two businesses ends up having to cease trading within five years. This is due to the damages it causes to real estate and IT Equipment etc., which prevent the company from continuing with their business.

Furthermore due to the impact of global warming and the change in climate, scientists have predicted that this is likely to increase the risk of extreme weather conditions, with as many as double or triple the amount of lightning strikes by 2050. Moreover the increased use of silicon-based, micro-controlled devices across our society are making businesses more and more at risk to the threats of lightning.

Insurance companies do not as yet encourage Lightning protection measures to be adopted as standard practice. To protect a business from the damage that could potentially be caused by lightning strikes, Lightning protection systems can be put in place. This system works by diverting the flow of electricity away from the structure and passing it through into the ground.

It is of vital importance that companies are properly protected against the risks of lightning destruction, as it has the potential to seriously affect a business. A disciplined and systematic approach to lightning protection should be adopted as this will reduce the risk, ultimately reducing the costs to a business.
