Debunking the Myth: Is there Really a Safe Level of Asbestos Exposure?

Adam Fox • 4 May 2023

The truth behind this myth and what it means for our health and safety

Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing due to its heat-resistant properties. It was only in the 1970s that the dangers of asbestos exposure became widely known, with studies linking it to lung cancer, mesothelioma, and other respiratory diseases. Despite this, the idea of a "safe" level of asbestos exposure still persists. In this article, we will explore the truth behind this myth and what it means for our health and safety.


Introduction to asbestos and its dangers


Asbestos is a group of six naturally occurring minerals that are composed of thin, needle-like fibres. These fibres are extremely durable and resistant to heat, making them ideal for use in insulation, roofing, and other construction materials. Unfortunately, when asbestos fibres are released into the air and inhaled, they can become lodged in the lining of the lungs, leading to serious health problems.


The dangers of asbestos exposure were first recognized in the early 1900s, with reports of lung disease in asbestos workers. Despite this, the use of asbestos continued to grow throughout the 20th century, with estimates suggesting that over 1.3 million people in the UK alone have been exposed to asbestos at some point in their lives.


What is the current safe level of asbestos exposure in the UK?


In the UK, the Control of Asbestos Regulations 2012 sets out strict guidelines for the management and removal of asbestos in the workplace. The regulations state that any work involving asbestos must be carried out by a licensed contractor and that exposure to asbestos fibres must be kept as low as reasonably practicable.


However, the regulations do not specify a "safe" level of asbestos exposure. Instead, they set a 'Control Limit' which currently sits at 0.1 f/ml.

Thats 0.1 fibres per cubic centimeter of air, or 100,000 fibres per cubic metre of air..... That's a lot of fibre!


The primary focus of the regulations is on minimizing exposure as much as possible through the use of effective control measures when working on asbestos containing materials, suitable protective equipment, safe work practices, and the removal of asbestos only where necessary.


The history of the control of asbestos regulations and current safety standards


The Control of Asbestos Regulations 2012 replaced earlier regulations from 2006 and 2002, which in turn built on the Asbestos (Prohibitions) Regulations 1992. These regulations were introduced in response to growing awareness of the dangers of asbestos exposure and the need to protect workers and the public from its harmful effects.


Today, the UK's safety standards for asbestos are among the strictest in the world. However, this has not always been the case. In the past, asbestos was used in a wide range of products, including building materials, insulation, and textiles, with little regard for the health and safety of workers or the public. This legacy of asbestos use continues to pose a significant risk today, with many older buildings and products still containing asbestos.


The limitations of current safety standards


Despite the strict safety standards in place today, there are still limitations to what can be done to protect against asbestos exposure. One of the main challenges is the fact that asbestos is often found in older buildings and products that are still in use today. This means that even with careful management and removal, there is always a risk of exposure.


Another limitation is the fact that asbestos-related diseases can take many years to develop, meaning that workers and members of the public may not show symptoms until decades after their exposure. This can make it difficult to track the true extent of the problem and to take action to prevent further exposure.


Understanding the risks of low-level asbestos exposure


One of the common myths surrounding asbestos exposure is that there is a "safe" level below which exposure is not harmful. However, this is not the case. Studies have shown that even low levels of asbestos exposure can increase the risk of lung cancer, mesothelioma, and other respiratory diseases.


This is because asbestos fibres are extremely durable and can remain in the lungs for many years, causing damage over time. In addition, the risk of developing an asbestos-related disease is thought to be cumulative, meaning that each exposure increases the risk further.


The long-term health effects of asbestos exposure


The long-term health effects of asbestos exposure can be devastating. Asbestos-related diseases can take many years to develop, and once they do, they are often fatal. Mesothelioma, a type of cancer that affects the lining of the lungs, is strongly linked to asbestos exposure, with around 2,700 people in the UK dying from the disease each year.


Lung cancer and asbestosis, a chronic lung disease, are also linked to asbestos exposure. These diseases can cause a range of symptoms, including shortness of breath, chest pain, and coughing, and can significantly reduce a person's quality of life.


What to do if you suspect asbestos exposure


If you suspect that you have been exposed to asbestos, it is important to seek medical advice as soon as possible. Your doctor can carry out tests to determine whether you have been affected and can provide advice on the best course of action.


If you work in a job that involves exposure to asbestos, it is important to follow all safety procedures and to wear protective equipment at all times. You should also be aware of the risks of exposure and take steps to minimize your exposure as much as possible.


Alternatives to asbestos in construction and manufacturing


Asbestos was once widely used in construction and manufacturing due to its heat-resistant properties. However, there are now many alternatives available that are safer and more environmentally friendly.


For example, cellulose fibre, rock wool, and fiberglass are all commonly used as insulation materials, while ceramic fibre and silica aerogel can be used in high-temperature applications. These materials are non-toxic, non-flammable, and do not pose the same health risks as asbestos.


Conclusion: Reconsidering the idea of a "safe" level of asbestos exposure


The idea of a "safe" level of asbestos exposure is a myth. Even low levels of exposure can increase the risk of serious respiratory diseases, and the long-term health effects of asbestos exposure can be devastating.


While current safety standards in the UK are among the strictest in the world, there are still limitations to what can be done to protect against asbestos exposure. The best course of action is to minimize exposure as much as possible through the use of protective equipment, safe work practices, and the removal of asbestos where necessary.


Ultimately, the only way to eliminate the risk of asbestos-related diseases is to stop using asbestos altogether. By investing in safer alternatives and taking action to remove asbestos from our buildings and products, we can protect the health and safety of future generations.


If you suspect that you have been exposed to asbestos, it is important to seek medical advice as soon as possible. If you work in a job that involves exposure to asbestos, make sure you follow all safety procedures and wear protective equipment at all times. And if you are concerned about the presence of asbestos in your home or workplace, contact a professional asbestos consultancy such as Consulo Compliance to carry out an inspection and advise you about removal if necessary. Let's work together to protect ourselves and our communities from the dangers of asbestos.

Asbestos and the Circular Economy: Why It's Time to Stop Burying the Problem Twenty-five years after asbestos was banned in the UK, we’re still digging a hole—literally and metaphorically. Every day, across the country, asbestos waste is double-bagged, labelled, loaded into skips, and driven to landfill, where it will sit indefinitely, taking up valuable space, creating ongoing liability, and adding to our already bloated environmental burden. And yet, 2025 presents a different path. A smarter one. One that replaces disposal with repurposing, and turns a dangerous waste product into a useful, circular resource. The technology exists. So the question we should be asking isn’t “Can we recycle asbestos?” It’s “Why the hell aren’t we doing it already?” Landfill is Failing Us—But We’re Still Relying On It Let’s start with the basics. There are still over 1.5 million buildings in the UK that contain asbestos, most of them now approaching the end of their useful life. As these structures age or undergo refurbishment, the volume of asbestos waste is only going to increase. Right now, we handle that waste the same way we did decades ago: • Identify it • Remove it (usually under fully controlled conditions) • Seal it in heavy-duty plastic • Drive it to landfill • Bury it • Forget about it Except we don’t forget, do we? Because landfill space is running out. Disposal costs are going up. And the environmental cost? We’re only just starting to count it. There’s a Better Way—and It Already Works Here’s what most duty holders don’t realise: We no longer have to bury asbestos. Thanks to recent advances in thermal treatment technology, we now have a method that can safely denature asbestos, breaking down its fibrous structure and rendering it harmless. Companies like Thermal Recycling in the UK are already proving this is not science fiction. They’re using high temperatures to transform asbestos cement products—like corrugated roofing sheets—into an inert ceramic material that’s completely safe. But here's the best bit: That material isn’t just neutral. It’s useful. It can be crushed and graded into aggregate, which can be used in road construction, paving, and concrete mixes. Instead of creating a waste burden for the next generation, we’re creating a valuable, low-carbon building material. Why Aggregate Matters in the Carbon Equation The production of virgin aggregates—through mining and quarrying—is energy-intensive and environmentally damaging. It contributes significantly to CO₂ emissions and destroys natural landscapes. So by replacing some of that demand with recycled aggregate from denatured asbestos, we: • Cut carbon emissions • Reduce dependence on extraction • Shrink the environmental footprint of infrastructure projects • Extend the life of quarries and reduce waste tonnage That’s not just a win for waste management. That’s a win for the entire construction supply chain. And yet most people in the industry don’t even know it’s possible. Why Are We Still Burying What Could Be Reused? As someone who’s worked in asbestos compliance for over 20 years—and now helps business leaders manage risk more intelligently—I’ve seen the same patterns play out time and time again: • “We’ll just do what we’ve always done.” • “This project’s tight on budget—landfill’s cheaper, right?” • “We’re just following the usual route—it’s less risky.” Let’s be honest. That mindset is outdated, short-sighted, and lazy. Cost may always be a factor, but the belief that landfill is “cheaper” needs to be challenged. Once you factor in: • Long-term environmental costs • Reputational risk • Rising disposal fees • And the public pressure for sustainable practices Thermal recycling is already starting to make sense. Especially when the output is something usable, not something buried. Licensed Contractors: You Don’t Get a Free Pass Either This isn’t just about clients or duty holders. Licensed Asbestos Removal Contractors (LARC’s) have a moral obligation here too. And I say that not from a place of opinion—but from first-hand experience, day in and day out for over two decades. Too often, LARCs put profits over progress. They default to landfill because it’s faster, easier to price up, and keeps their margins clean. They know the alternatives exist—but they don’t explore them, let alone offer them to their clients. When you hold a licence from the HSE, you’re not just a business—you’re a guardian of public health. That comes with responsibility. Choosing the most sustainable, forward-thinking disposal route should be part of that. Especially when the technology is available, proven, and legal. It’s time for the industry to stop hiding behind what’s convenient and start leading from the front. A Moral Obligation for Everyone Involved Whether you’re a: • Local authority managing public buildings • Developer under pressure to go green • Commercial landlord looking to reduce liability • Or a licensed contractor with influence over disposal routes —you have a responsibility to look beyond the cheapest or fastest option. If there’s a proven, safe, and more sustainable way to manage asbestos, you have a duty to understand it before choosing to ignore it. Because let’s be honest: “We didn’t know” isn’t going to wash when the public starts asking why we’re still filling landfill sites with a problem we already have the technology to eliminate. So What Can You Do Differently? No one’s asking you to overhaul your entire waste strategy overnight. But you can—and should—start asking better questions: • “Is landfill our only option here?” • “Could this waste stream be recycled instead of buried?” • “What suppliers, contractors, or experts do we know who can help us explore this?” You don’t have to be a global pioneer. But if you’re in a position of responsibility, you should at least be aware that the old way isn’t the only way anymore. Final Thought: The Future Is Circular—Whether You Join In or Not Asbestos will be with us for decades to come. That’s a fact. But how we handle it—and whether we choose to keep repeating the past or do something smarter—is up to us. Thermal recycling and other denaturing technologies offer a rare opportunity to do something that actually moves the industry forward. Not just ticking the compliance box. Not just burying the problem. But solving it—and turning it into something useful in the process. If you’re involved in asbestos management in even the slightest way, ask yourself this: Are you part of the problem, or part of the solution?
