Did you know that lightning strikes are becoming more frequent? Climate change and increased use of electrical technology mean lightning strikes are becoming an increasing concern to tall buildings and exposed structures.
Electricity gradually builds up during a thunderstorm and once it has enough energy, a giant spark occurs (like static electricity) this can happen between clouds and air, and often it is routed through the ground in the form of a lightning strike.
What is Lightning Protection?
Lightning looks for the quickest route to the ground, and often this can mean it strikes buildings in its hunt for the path of least resistance. This can pose serious danger if the spark occurs near exposed gas or electricity infrastructure.
Many tall buildings; such as churches and skyscrapers, have lightning protection conductors installed, to avoid significant damage and danger should a lightning strike occur.
Lightning conductors are not usually installed on homes, as the likelihood of lightning striking houses is relatively low, but it can happen. If your home is exposed or in an area that frequently experiences thunder and lightning storms however, it could be worthwhile investing in lightning protection to avoid any damage.
How Does It Work?
Lightning conductors (also known as lightning arrestor’s, lightning diverters, lightning rods or cables.) are a type of Lightning Protection System. Lightning conductors and special earthing equipment ensure that electrical currents are routed to the ground via a path of least resistance, thereby preventing damage to the building.
Usually made out of conductive materials such as copper and aluminium, lightning protection systems are usually installed on the outside of a building or structure to help prevent power surges.
Lightning protection cables and equipment will need to be replaced every so often, depending on the amount of wear and tear placed on them over time.
Lightning Protection Law In The UK
Lightning causes millions of pounds worth of damage and hundreds of injuries across the world each year, both as a direct result of lightning strikes and from the resulting electrical surges.
Compliance with UK legislation requires that a risk assessment be carried out on the premises first of all (in accordance with BS6651 and BSEN:62305).
The risk assessment is a visual inspection and helps to determine the likelihood of lightning striking a building, and the potential dangers this poses. The building is then given a category depending on how high the risk of hazard is to life and the potential damage to physical structures.
Lightning Protection Systems have different categories depending on the type of building they are due to be installed on. The Lightning Protection System on a building must be the same grade as the Lightning Protection Level. For example, if the threat level is one, the lightning protection system must be 1 or higher to be within the legal requirements.
The potential thermal and explosive effects of a building are taken into consideration in both internal and external Lightning Protection Systems. An external system must have all three requirements: an air termination system, a down conductor system and an earth termination system in accordance with BS EN/IEC 62305 codes.
Penalties For Non-Compliance
Although it is not a legal requirement for all buildings and structures to have lightning protection, it is mandatory to have a risk assessment done annually to ensure that all LP systems meet statutory compliance. The Electricity at Work Regulations 1989 apply to businesses in the UK, and Lightning Protection Systems that do no meet the current standard pose a serious risk of injury and potential loss of life.
Structures Most Likely to Be Struck by Lightning
Parts of a structure most likely to be struck by lightning are those that protrude from the surrounding structure.
Some examples of common structures likely to be struck by lightning:
●Elevated Water Tanks;
●Radio, Television, Mobile Phone and Microwave masts.
How Does Lightning Testing Work?
Your lightning protection system should be tested no more than 12 months apart. However, it is highly recommended that your system is tested throughout the year to ensure it can withstand the elements of all seasons.
A properly maintained lightning system will last for many years and will ensure your building is protected from lightning strikes and the consequent power surges.
What Do Lightning Tests Or Recommendations Involve?
●Inspection of current lightning conductors including joints and parts of the system
●Continuity testing across the whole lightning protection system
●Earth resistance testing on individual electrodes and the complete system
●Reports on the condition of the system
●Recommendations of required repairs, with reliable estimates included
A lightning protection test is a great opportunity to understand if your building is at risk to lightning, or if your lightning protection system requires servicing and maintenance to be deemed safe and in good working condition.
Lightning Damage Insurance
Although lightning striking houses and phone lines is quite rare, it definitely happens. Insurance policies can vary depending on the company and level of cover you have.
Most insurance providers do include damage caused to property and possessions by lightning in their policy, but it is certainly worth looking into it to be absolutely sure.
Many lightning protection companies offer insurance and warranty on lightning protection systems, so it is worth checking whether this is included when deciding on a company to install lightning protection on your building.
How To Protect Your Home From Lightning Damage
lightning strikes your house or nearby power lines, it can follow the wiring or phone lines and cause a power surge to the circuits in your home. This can ruin TV’s, stereos and anything else plugged into the mains. To avoid your gadgets being “fried” by lightning, unplug them during a thunderstorm and disconnect internet, antenna and satellite-dish connections, even if they are grounded.
Invest In Surge Protectors
These are electrical devices which you plug your appliances. These are very low cost, considering the possible impact of lightning damage is potentially hundreds of pounds. Surge protectors are most effective for indirect lightning strikes (such as to powerlines and the electrical grid) but in serious cases where lightning directly strikes a building which is far more drastic and dangerous, surge protection is not likely to be of much use.
Myths Around Lightning Protection
Do Lightning Protection Systems Attract Lightning?
Many people think lightning protection systems attract lightning. This is simply not the case. A lightning protection system doesn’t attract lightning or dilute the power of a storm, nor does it act as a building surge protector that means all electronics will be protected. It works to protect the building from fire or serious structural damage in the event it is struck by lightning.
Lightning Can’t Strike The Same Place Twice
This is another myth surrounding lightning that is untrue. Thunder and lightning storms usually travel through an area quickly, and once it has struck one place the likelihood of it striking again is lower, but it is certainly still a possibility. Exposed objects that are effective electrical conductors are usually prime targets for lightning to strike twice, as they provide the path of least resistance for lightning to reach the earth.
You Are Safer Outdoors
This is also incorrect. During a lightning storm, you are not safe anywhere outdoors. Ensure you get under a substantial building or hard-topped vehicle. Avoid touching anything electronic plugged into the mains and certainly avoid roofs!
If you need reliable lightning protection for commercial, domestic or any other type of building, get in touch with Rodell’s today. We have a wealth of industry experience offering lightning protection services; including design, testing and inspection. We have provided safe and reliable lightning protection to schools, churches, colleges, commercial, domestic buildings and many more, so no matter what building type, we can help plan a solution that works for you.
Here in the UK, we’re blessed with relatively calm weather. However, while we might not be subjected to hurricanes or tornadoes, we do get our fair share of electrical storms. On average, the UK and its surrounding waters are hit by around 300,000 lightning strikes every year, and while these powerful displays of nature are stunning to watch, they also pose significant risk to both people and structures.
While the dangers of being struck by lightning are exceedingly low, buildings can be put at risk, which can also endanger those inside. With this in mind, you may be wondering what your responsibilities are when it comes to protecting your premises against the threat of a lightning strike. As lightning protection experts, we at Rodell’s decided to demystify the process and give you the lowdown on what you need to do.
Complying with the law
As a country with a much lower risk of lightning strikes in comparison to other countries around the world, the UK doesn’t actually have laws specifying lightning protection all for buildings and structures. However, what it does have is a set of rules under the Electricity at Work Regulations 1989 that applies to businesses.
Specifically focusing on BS EN/IEC 62305, businesses are required to ensure that electrical installations and the business premises itself are protected from lightning strikes.
What is required?
Under the regulations, there are four ‘lightning protection levels’ known as LPLs. These LPLs focus on the protection of four different aspects of a business, ranging from S1 to S4. S1 focuses on protecting strikes to the structure itself, S2 for strikes near the structure, and S3 and S4 are focused more around services connected to the main structure, such as warehouses and parking spaces.
In order to remain compliant with BS EN/IEC 62305, a company must have an inspection carried out by a licenced professional and invest in lightning mitigation installations such as surge protection to keep your electronic equipment safe and lightning rods to ground your building.
What are the penalties?
As lightning protection falls under the Electricity at Work Regulations 1989, it is essential to ensure that you remain on the right side of the law. If you are found to be ignoring these regulations or if someone is injured due to your business not having adequate protection, you could find yourself in extremely hot legal hot water. With this in mind, it’s essential to make sure you’re compliant.
Protect your business from lightning strikes with Rodell’s
Lightning strikes are powerful yet dangerous displays of nature, which is why you should ensure your business is properly protected. As suppliers of quality lightning protection solutions, from lightning rods to comprehensive inspections, our team will ensure you’re compliant to regulations.

This Hertfordshire city is only 20 minutes from the bustling hub of London, but it has a wealth of history and charm all of its own. There are plenty of stunning buildings to visit, from the city’s ancient cathedral to the famous clock tower. If you'd like to know more about just four of the beautiful buildings to be found in St Albans, see our brief guide below.
St Albans Cathedral
This cathedral is a shrine to Britain's first Saint, and it's the oldest site of Christian worship in Britain, too. Often referred to locally as ‘the Abbey’, the cathedral began to be built all the way back in 1077. Nowadays, the cathedral still plays host to a wide variety of events, including talks, concerts and educational courses.
The clock tower is actually a Grade I listed belfry, constructed all the way back in 1403. It's thought to be the only remaining medieval town belfry left in England and it was originally constructed as a protest against the power of the abbey. The clock tower bell was rung to announce the first Battle of St Albans during the Wars of the Roses in 1455.
Built in 1140, this ancient building is also referred to as the Sopwell Nunnery. The ruins visible today are actually from a mansion belonging to an advisor of Henry VIII, but the area is still referred to as Sopwell Priory. It's a popular spot for a picnic during the warmer months and is close to several picturesque walking trails.
Redbournbury Watermill and Bakery
This Grade II listed eighteenth-century building is still a working Watermill museum and bakery today. The mill produces organic stoneground flour and handmade loaves are produced in the bakery for visitors to purchase. The mill is also a World Heritage Site and is one of St Albans’ most popular attractions.
Here at Rodells Ltd, we believe in the importance of keeping the buildings of St Albans in tiptop condition. With over 100 years experience in the business, we’re proud to offer scaffolding services, lightning protection and specialist works and have provided many of these services to St Albans buildings.

Earth rods are essentially used as their fittings provide the interface to ground in all soil conditions in order to achieve a quality earthing systems in the overhead and underground electricity distribution and transmission networks, this provides high fault current capacity on low, medium and high voltage substations, towers and power distribution applications.
Convenient to install where the subsoil condition is free from rock and boulders the earth rod or group of copper rods can be surrounded or backfilled using a low resistance material such as Bentonite. With this in mind, here in this blog we will outline to you a brief guide to earth rods detailing what you need to know.
Why are earth rods so useful?
Dependant on the corrosive condition and electrical conductivity of the ground condition the earth rod can be specified to allow you safe, consistent and long term earthing protection, the mechanical strength of the rod has to withstand the abrasion and stress endured while installing with an electric or pneumatic driving rod hammer; the head of the earth rod should not ‘mushroom’ or spread outwards when driven. Earth rods are extendable in their design and used with copper couplers to connect several rods to achieve the necessary driving depth - the rod couplers provide permanent electrical conductivity and the longer copper earth rods access lower resistivity soils at lower depths.
Vertically driven earth rods tend to be the most effective electrode for usage in typically smaller areas of substations or when low soil resistivity ground conditions, into which the rod can where the rod can penetrate, lies underneath a layer of high soil resistivity.
Earth Rods Diameter v Length
A frequently made misconception is that there is a direct and clear correlation between the diameter of the earth rod used and the effect on lowering earth resistance readings, this however is false.
The resistance value is only decreased by 9.5% by doubling the diameter of the rod, which means increasing the weight and the cost of the rod by approximately 400%. Thus the logic is: use the most economical earth rod that soil conditions will permit the installer to drive.
The general rule of thumb seems to be doubling the radius of the earth rod will reduce resistance by approximately 10% and is not a cost-effective option. Doubling the rod length, however, will theoretically reduces resistance by 40%.
Additional driven earth rods are placed together and connected, they should be separated from each other and from any adjacent cables by a distance not less than the depth to which they are driven. On top of this, earth rods should be connected using copper tape or bare copper cable of the same cross-sectional area as the earth electrode conductor. The additional electrodes should be placed so that any necessary separation of the LV and HV earth electrode systems is maintained.
Copper bonded steel core earth rods are the highest specified due to electrical and mechanical strength, resistance to corrosion as comparatively lower cost compared to solid copper or stainless steel types – the lowest cost galvanised rods for usually installed non-critical, short-term or temporary earthing needs.
Installation of earth rods
Earth rod electrodes are installed during the civil engineering works associated with substation construction – soil resistivity readings are taken and if “greater than 200m, basically, vertical earth rods are installed to reduce resistance. Note consult local UK DNO or utility recommendations which vary according to engineering standards and preferences.
Safe working practices recommend when driving earth rods all necessary steps should be taken to ensure that rods are not driven into any buried services below cable trench level such as gas, telephone, water or electricity cables. Contractors should consult the appropriate utilities’ records and the use of approved instruments for the detection of buried services may also be necessary - this is especially important when rods are installed after the completion of cable pulling and laying.
Change of earth rod diameter has marginal impact on the overall value of resistance with the size determined by the mechanical and structural strength of the rod to withstand being mechanically driven when deep earth rods are required e.g. to depths of 20 metres or more.
Driving copper earth rods is often conducted in more built-up urban locations and the method should be used with care, caution and implemented measures to prevent accidental damage to buried utility services, such as 11kV/33kV high voltage cables. The rods are driven vertically into the ground and earth resistance is measured as each section is installed.
Installing a ground rod will redirect current from any electrical circuit you may have into the ground where it is located. It is crucial for any home to prevent a small short circuit from turning into an electrical fire. In the event your electrical systems malfunction, the grounding rod will vanish all the released current away from your property and down into the ground.
Why do earthing and bonding need to be checked?
If you are having an alteration of addition made to your electrical installation, your electrician must check (as well as other things) that the earthing and bonding arrangements you have are up to the required standard.
This is because the safety of any new work you have done (however small) will depend on the earthing and bonding arrangements.
What is earthing?
If there happens to be a fault in your electrical installation you could very easily get an electric shock if you touch a live metal section of it. This is because the electricity may use your body as a path from the live part to the earth part.
Earthing is used to protect you from any kind of electric shock. It does this by providing a path, essentially a protective conductor for a fault current to flow to earth. It also causes the protective device either a circuit-breaker or fuse to switch off the electric current to the circuit that has the fault.
An example of this being, if a cooker has a fault, the fault current flows to earth through the protective (earthing) conductors. A protective device (fuse or circuit-breaker) in the consumer unit switches off the electrical supply to the cooker. The cooker is now safe from causing an electric shock to anyone who touches it.
What is bonding?
Bonding is used to reduce the risk of electric shocks to anyone who may touch two separate metal parts when there is a fault somewhere in the supply of electrical installation. By connecting bonding conductors between particular parts, it decreases the voltage there might have been.

Lightning is unusual at the very best of times and has been the subject of much investigation by scientists over the centuries. It’s also been the basis for a number of religious myth and cultural tradition. However, no matter how awe-inspiring lightning can be, it seems to always throw up more surprises; here are just a few.
Lightning Partially Cured Blindness
Absolutely astonishingly, lightning is credited with partially curing a man of his blindness! This bizarre story is centred around a man named Edwin Robinson; a 62-year-old living in Maine in 1980 who had lost his eyesight in a car accident nearly a decade before and found that he had regained some of his eyesight after being struck. He may have been unlucky to be struck at all, but he was particularly lucky to have this outcome.
‘Bolts From The Blue’
You may have heard of the phrase a ‘bolt from the blue’ and been wondering where it comes from. A bolt from the blue is a lightning bolt which comes from a storm many miles away so that it seems as though it has come from nowhere. These are very rare but, nonetheless, there have been reports of people and buildings being struck on what seemed like a perfectly clear day.
The Man Who Survived Seven Strikes
Roy Sullivan was a park ranger in the Shenandoah National Park, Virginia, USA and was struck by lightning a staggering seven times. Even more astounding, however, is that he survived them all and died in totally unrelated circumstances sometime later. Between 1942 and 1977, Roy was struck seven times making him statistically one of the world’s most unlucky people.

Lightning is awe-inspiring, but it can also be very dangerous. Here we describe some of the most devastating accidents caused by lightning.
Brescia, ItalyBack in the year 1769, the town of Brescia in Italy suffered from a terrible accident caused by lightning. In the vaults of the Church of the Nazaire in the town, nearly 94 tons of gunpowder was being stored when lightning struck. Travelling through the building to the vault, the ensuing explosion killed 3,000 people and destroyed around a sixth of the city. The destruction of the accident meant that much more effort was made to ensure gunpowder was stored safely and securely in the future.
Pan American Flight To PhiladelphiaOne of the world’s worst lightning-related death-toll happened in 1963 when a Boeing 707 was struck by lightning as it travelled from Puerto Rico to Philadelphia. Tragically killing all 81 people on board, the aeroplane exploded in mid-air during the flight as the lightning hit a reserve fuel tank. The intense heat melted the rivets in the structure and fused materials together. This tragedy created a need for all airliners to be fitted with lightning discharge wicks.
Yellowstone FiresIn 1988, one of the very largest fires in the history of Yellowstone spread across the park and affected more than a third of it. This caused mass-evacuations and - to this day - hikers are still advised to watch out for the potential of falling trees which were damaged in the fire. The fire was started via a mixture of very dry weather, high winds and a number of lightning strikes.

From retail to restaurants, it is vital that the exterior of your business looks inviting and well-kept as this will attract a multiplicity of customers to walk through your door. Although renovations may initially seem costly and time-consuming, they can certainly pay off; giving your business perhaps a much-needed facelift. With the increasingly competitive field of the high street, having a business exterior that stands out amongst other competitors is vital for longevity.
However, who should you call if you want to have your business exterior revamped? From building contractors to roofers and exterior decorators, none of these could do their job without commercial scaffolding erection. Commercial scaffolding hire is catered specifically to businesses, offering a specialist service that accommodates to the business owners needs. For example, unlike domestic scaffolding, commercial scaffolding may intrude onto public thoroughfares like busy streets, so it will need to be constructed differently.
Choosing a trusted commercial scaffolding hire company is key to having your needs, high safety standards and other considerations met. Below, we take a closer look at how a commercial scaffolding hire company is an asset with business renovations.
Commercial scaffolding can help businesses of all shapes and sizes
In comparison to domestic scaffolding, commercial scaffolding can accommodate to businesses of all shapes, sizes and building types. This is because commercial properties can come in a large range of architectural variation than the average domestic property, meaning that commercial scaffolding needs to be adaptable.
Infact, many businesses like banks, art galleries, public schools, bars, restaurants and retail are in grade listed and historic buildings, meaning that maintenance renovations need to be carried out with precision and to a high standard. With this in mind, scaffolding can be erected which isn’t bolted onto the building, meaning that the building’s exterior is not damaged.
On commission of a project, commercial scaffolding companies will design a bespoke scaffolding structure that will fit the dimensions and requirements of the business. From this, they can help build a quote of how much scaffolding will cost and they will determine what kind of scaffolding you need.
There are a range of options of scaffolding available from temporary scaffolds to permanent structures. For example, if you are just repainting a shop sign, you may only need a temporary and portable scaffold structure. However, if you are repainting the whole building, adding new windows or building an extension, a long term structure will be needed.
Can help increase the layout and space of business
Having commercial scaffolding made for your business renovation extends the amount and type of renovations you can have performed rather than hindering them. For instance, if the scaffolding is erected primarily for window installation, why not get the business exterior painted too? Or, if you are having your roof fixed, why not see if you can have your business extended and made bigger?
Commercial scaffolding allows you to safety and flexibly make the adjustments and renovations to your business as you desire. For instance, it can help support the business’ structure as you either build another floor or another room.
Increasing the space and, consequently, the layout of your business will have a range of benefits. Not only does it signify that your business is successful and expanding, but also it will allow you to hire more employees, creating a more comfortable working environment, add recreational spaces, and add more meeting rooms.
Improving the exterior of a businesses’ building has a range of benefits
Commercial scaffolding hire allows you to improve your business’ exterior. A worthy investment, improving your business’ exterior, whether just an office space or hotel, offers a range of benefits.
Improving your business exterior is one of the best ways to attract customers, clients, potential employees and build a brand. In this day and age, one of the best ways to attract customers is through the use of free marketing tools like Instagram. For example, ‘instagrammable’ interiors and exteriors will prompt customers, clients and employees to take a photo and share on social media, creating positive rapport and a buzz for your brand. Some of the most famous examples of these are the bakeries Peggy Porschen Cakes and the Biscuiteers in London.
As the saying goes, ‘first impressions count’ and with a stunningly chic and well-presented shop exterior or office, this is certainly where it applies. Having a well-presented exterior indicates to clients, customers, and potential employees that you work to a high standard, you have high-quality products to sell and you are successful. In retail, this could prompt for customers to shop there often as with the boom of e-commerce offering a valuable in-person shopping experience is important. For offices, a well-kept exterior could allow you to secure potential investors or new clients.
There are a range of ways you can improve the exterior of your offices, retail business, hotel or restaurant. If in an urban area, why not have a spray-painted mural, or have it painted in a crisp pastel hue? Alternatively, if you just want to spruce up the space rather than make the statement, you could have your windows cleaned and the stones pressure-washed.
What’s more, once the scaffolding is erected and you are having the exterior of your business improved, the contractors could also identify any structural issues that need repairing or just some TLC. Therefore, the safety of your exterior could potentially be improved too. A tired, dilapidated and business exterior that is falling apart is never going to be attractive.
Properties of reputable commercial scaffolding services
Once you have decided that commercial scaffolding hire can benefit your business in a range of ways, now it comes to finding the right scaffolding business. In fact, finding the right scaffolding services can actually improve the renovations that are taking place. Below, we indicate the importance of finding the right scaffolding company, and how to spot the best.
AccreditationsA hallmark for a business’ success, accreditations like the Scaffolding Association, the National Access and Scaffolding Confederation, and Contractors Health and Safety Assessment Scheme will prove to the customer that their business’ practises have been tested and approved to a high code of conduct. Choosing an accredited company will not only give you peace of mind that the work carried out will be of a high standard, but it also is a third-party organisation that you can take up any complaints with.
TestimonialsSimilarly to accreditations, positive testimonials and recommendations are more valuable than ever in finding a reputable business. If you are hiring a company for a service, you want to be assured that you can trust them to perform it well. Testimonials are a first-hand written experience from another customer, you can find them on their website, on google or by contacting the company.
ExperienceThere is nothing that can teach you more in life than first-hand experience, and if you are a business whose financial future will depend upon your renovations, then you should certainly choose a scaffolding company with years of experience under their belt. Especially a scaffolding company that has experience dealing with your kind of business, listed buildings the particular renovations you want to be performed.
SafetyCommercial scaffolding hire can pose a few health and safety risks if not assembled correctly. For instance, as it would be installed on a public building, the contractors and the general public would both potentially be at risk if the scaffolding was loose. With this in mind, you can pose certain threat to the public, however, a commercial scaffolding company with the qualities listed above would ensure that a safe installation would occur.
Minimum disruptionIf you are planning on minimal renovations, it is likely that your business will need to continue its day to day operations whilst the scaffolding is being installed and the renovations are taking place. With this in mind, you certainly don’t want the clanking and banging of installation to interrupt or hinder your staff’s productivity. An experienced commercial scaffolding company will understand this and will make sure that they cause minimum disruption to your day.
Sticks to deadlinesIf you are having major exterior renovations like for a hotel, restaurant or retail, then it is likely that you may have to temporarily close. However, especially if the renovations are designed to boost your business, you will know how important it is for deadlines to be strictly kept to and met. After all, time really is money! With this in mind, an experienced commercial scaffolding company will understand this, and will endeavour to make sure all deadlines are met in good time, so you can re-open without a hitch.

We all see scaffolding almost everyday, especially if you live in a city. But have you ever wondered where the idea of using scaffolding came from? Well, we’re going to take a quick look at where scaffolding all began and how it has developed over time.
The Start of Scaffolding
The truth about where scaffolding started is that we don’t entirely know, but what we do know, is that it was a long time ago. The earliest signs of scaffolding that we’ve found so far are over seventeen thousand years old.
We don’t exactly know what the scaffolding structures would have looked like, but there is evidence to suggest these did exist. Paleolithic cave paintings that were discovered in 1940 in Southern France show the earliest signs of scaffolding. Both the height of the cave paintings and sockets found in the wall suggest that some kind of early scaffolding system was used to achieve these ancient artworks.
Scaffolding structures were also used in more recognisable historic creations, notably the ancient Egyptians and Greeks famously using scaffolding for some of their grand structures that even stand still stand today. Testament to those who built them.
When we fast forward to the Victorian era, there was still no industry standard when it came to scaffolding sizes or even the materials that were used to create the scaffolding structures. Many used wood or even bamboo scaffolding structures, which are still commonly used across many countries around the world today.
Though, a scaffolding revolution was about to happen. In 1913, Daniel Palmer Jones invented a coupling system for scaffolding which led him down a path of invention. His creations led to a standardisation across the scaffolding industry. This helped to make working with scaffolding safer for all involved.
Scaffolding As We Know It
Nowadays, scaffolding is a regulated industry with standardised practices used to keep those using the scaffolding safe, as well as members of the general public. As it stands, all scaffolding in the United Kingdom must meet European Standards, something that we at Rodells, of course, adhere to.
Here at Roddells, we are a specialist works and access company that has operated since all the way back in 1898. We’re based in Hertfordshire providing scaffolding services and lightning protection, with a focus on high-quality and affordability. If you require our services, get in contact with our friendly and experienced team, who will help to find the perfect solution for you.
Have you ever sat through an epic thunderstorm and watched stunning bolts of lightning streak across the sky only to think “how does that work?” With over 100 bolts of lightning striking the earth every second on average, it’s likely you’ve seen this beautiful, yet deadly, natural display countless times before.
However, whilst this breathtaking natural phenomenon is constantly happening across the globe, you may be surprised to know that scientists still aren’t quite sure how it works - luckily, we’re slowly filling in the gaps.
The water cycleWhen it comes to understanding thunderstorms, it’s best to start with the water cycle. As water is evaporated by the sun, the subsequent vapour forms clouds thanks to condensation. Once enough water condenses, the water forms into droplets we know as rain and snow; the rainwater will then make its way back to the ocean.
It is within these rising and falling clouds of water vapour that lightning is both created and dispersed, meaning that areas with high precipitation and humidity levels are most affected by lightning strikes.
CollisionsWhilst scientists are not completely sure how huge charges of electricity are created in the atmosphere, there is a plausible explanation that many researchers ascribe to. As we now know, clouds are simply condensed water and ice evaporated from the world’s oceans. These clouds contain millions of water particles that are constantly rising and falling as evaporation and condensation continues.
Scientists believe that these droplets collide with each other, with the heavier condensed water knocking electrons from rising vapour as it falls. These knocked off electrons gather at the bottom of a cloud, creating a positive charge, while positively charged moisture builds at the top, creating a charge separation.
FreezingFreezing also plays an important role within scientists’ theory of lightning. As moisture reaches the upper regions of the cloud, it begins to freeze, giving it a positive charge while the unfrozen portions have a negative charge. By combining collisions and freezing within a cloud, enough charge is theoretically created to produce the vast amount of energy required for a lightning strike.
StrikesOnce an electric field has been produced thanks to the positive and negative charges within a cloud, the negative charge in the lower regions of the cloud begin to attract the positive charge built up in the ground below. Once the positive charge meets the negative, a lightning strike occurs.
