Asbestos has been a part of the UK’s construction industry for well over a century. While it’s no longer used in buildings, it can still often be found in thousands of homes, schools, commercial units, and industrial sites built before 2000. Understanding the dangers of asbestos is particularly essential for anyone involved in property maintenance, refurbishment, or development.
In this blog, we explore the main risks of asbestos, when it becomes hazardous, and how to deal with it safely and responsibly so you have a clear and practical overview of this material.
Why was asbestos used and why is it now a concern?
Asbestos was commonly used throughout the 20th century due to its useful properties. It’s resistant to fire, heat, electricity, and corrosion, and it’s easy to blend into materials like cement, insulation, and flooring. Because of this, asbestos found its way into a huge range of products – from roofing sheets and ceiling tiles, to pipe lagging and textured coatings.
However, over time, the hazards of asbestos became more widely understood. The concern isn’t with the material itself when left intact and undisturbed, but more with what happens when asbestos fibres become airborne.
When asbestos-containing materials (ACMs) are damaged, degraded, or disturbed, tiny fibres can be released into the air. These fibres are too small to see with the naked eye and, once inhaled, can remain in the body for many years. This is the foundation of most of the dangers of asbestos; not from touching it or seeing it, but from unknowingly breathing in its fibres.
Understanding the risks of asbestos exposure
It’s important to be clear – asbestos is not automatically dangerous in all settings. In many situations, low-level asbestos exposure presents minimal risk, particularly when ACMs remain intact and undisturbed.
In older buildings, asbestos is often found within products such as vinyl floor tiles, textured coatings, or bonded materials where the fibres are encapsulated within a solid matrix. When left in good condition, these materials significantly reduce the likelihood of fibres being released into the air under normal day-to-day use.
Routine activities, such as walking over intact asbestos flooring or carrying out general cleaning, also don’t typically result in hazardous exposure levels. The risk remains low as long as these materials aren’t drilled into, sanded, broken, or aggressively removed. This is why asbestos present in good condition doesn’t always require immediate action.
However, there are certain conditions where the risks of asbestos increase significantly, such as:
- Disturbance during building work – as mentioned, renovation works, drilling, demolition, or sanding can all cause asbestos fibres to be released if ACMs are present.
- Deterioration over time – as asbestos materials age, they may begin to break down. Weathering, vibration, or even poor storage conditions can all cause wear and tear.
- Accidental damage – even a minor incident, like knocking through a wall or removing old tiles, can expose asbestos layers beneath.
- Lack of awareness – in some properties, the presence of asbestos isn’t known at all, increasing the chance that it’s unknowingly disturbed.
In all of these situations, it’s not the presence of asbestos alone that’s the issue, it’s the potential for fibres to become airborne and for people to be exposed without proper protection or controls in place.
Why are the dangers of asbestos taken so seriously?
One of the most important things to understand about asbestos is that its effects often take years – or even decades – to become apparent. This long delay between exposure and potential health issues is one of the main reasons it’s so strictly regulated in the UK today.
The dangers of asbestos are recognised in many industries and government guidelines, like the Health and Safety Executive (HSE). The Control of Asbestos Regulations 2012 sets out strict rules on how asbestos must be identified, managed, and, if necessary, removed. These rules apply to anyone responsible for a non-domestic premises, as well as, contractors working in domestic environments.
It’s also why you’ll hear asbestos referred to as a “hidden danger”, because without professional testing, most people can’t tell whether a material contains asbestos just by looking at it.
Examples of asbestos-containing materials
We touched on this briefly previously, but the hazards of asbestos often arise from common materials found in older properties. Some of the most common examples include:
- Insulating board used for fireproofing or partition walls
- Artex and other textured coatings applied to ceilings or walls
- Roofing sheets, especially corrugated garage or outbuilding roofs
- Floor tiles and adhesives beneath carpet or vinyl
- Pipe insulation, particularly around old boilers or heating systems
- Cement panels or guttering in older industrial or agricultural buildings
These materials don’t always appear dangerous, but if they’re disturbed or damaged, they can present a significant risk if asbestos is present.
How to approach asbestos safely
The good news is that the risks of asbestos can be managed effectively, so long as the correct procedures are followed. Approaching asbestos safely requires a few key steps to avoid unnecessary exposure and ensure that any action taken is both safe and legally compliant.
The dangers of asbestos comes from not knowing it’s there, disturbing it by accident, or trying to handle it without the right training. However with professional guidance, like the advice our experts can provide here at Midlands Asbestos Solutions (MAS), most asbestos-related situations can be managed calmly, safely, and effectively.
Whether you’re a homeowner planning renovations or a facilities manager responsible for multiple sites, the best approach is always to be informed, proactive, and compliant with UK regulations. If you’re unsure on how to manage asbestos, you can contact us for specialist advice on what to do.

FAQs around the dangers of asbestos
Is any asbestos safe?
No type of asbestos is considered entirely safe. While ACMs may not pose an immediate risk when in good condition and left undisturbed, the dangers of asbestos arise when those materials are damaged or disturbed. This can release microscopic fibres into the air, which may be harmful if inhaled. Because of this, all forms of asbestos are treated with caution under UK regulations.
What is dangerous about asbestos?
The primary risk of asbestos lies in its fibres. When ACMs are cut, broken, or allowed to deteriorate, they can release fibres into the air. These fibres are not visible to the naked eye and can remain suspended in the air for long periods. If breathed in, they may remain in the body for many years. This is why the hazards of asbestos are taken seriously and why strict controls are in place to prevent unnecessary exposure.
What is the most dangerous type of asbestos?
There are several types of asbestos, and all are considered hazardous. The three most commonly found in the UK are crocidolite (blue asbestos), amosite (brown asbestos), and chrysotile (white asbestos). Blue and brown are generally regarded as more hazardous due to the nature of their fibres. However, no type of asbestos is considered safe.
