Mastering Asbestos Awareness: Safeguarding against the invisible threat

Asbestos is a naturally occurring mineral that crystallises into lots of small fibres. Generally speaking, if asbestos is not damaged and remains intact, it is not dangerous. However, should the asbestos be damaged or disturbed, fibres can become airborne, and prolonged exposure to asbestos fibres can have severe health consequences, making asbestos awareness essential.

This blog aims to shed light on the importance of understanding asbestos, its pervasive presence, associated health risks, and the imperative need for effective management. Whether you’re a professional in construction, renovation, or concerned about the safety of your environment, grasping the fundamentals of asbestos awareness comes first.

What is asbestos?

Asbestos has been extensively used in construction materials, including insulation, roofing, flooring, and cement, as well as in automotive parts, textiles, and other products. Asbestos is fire-resistant, resistant to water, and has great insulating properties, which made it attractive for many applications.

Due to the recognised health hazards, many countries have implemented strict regulations and restrictions on the use of asbestos.

In some regions, it is completely banned, while in others, its use is heavily regulated to minimise the risk to workers and the general population.

Asbestos removal and remediation procedures require specialised training to ensure safe handling and disposal of the material.

In 1999, the UK government implemented a ban on the import, supply, and use of asbestos-containing materials. Strict regulations and guidelines are now in place for the management, removal, and disposal of asbestos-containing materials to protect workers and the general public.

The six types of asbestos

There are six common types of asbestos minerals, which are classified based on their chemical composition and physical characteristics. All types of asbestos are hazardous to human health when their fibres are released and inhaled, and strict safety precautions should be followed when handling any asbestos containing materials.

The six types are as follows:

Chrysotile (white asbestos): Chrysotile is the most commonly used type of asbestos. It has curly and flexible fibres that are resistant to heat and chemicals. Chrysotile asbestos was widely used in various construction materials, including insulation, roofing, and friction products.

Amosite (brown asbestos): Amosite has straight, brittle fibres that are known for their excellent heat resistance. It was commonly used in insulation boards, cement sheets, and pipe insulation.

Crocidolite (blue asbestos): Crocidolite has blue-coloured, thin, and sharp fibres. It is considered the most dangerous type of asbestos due to its high toxicity, and was used in applications where resistance to high temperatures and chemicals were required, such as in spray-on coatings and insulation.

Tremolite: Tremolite asbestos can occur in various colours, including white, grey, green, or transparent. It is often found as a contaminant in other minerals, such as talc, vermiculite, and chrysotile asbestos.

Anthophyllite: Anthophyllite asbestos typically appears as brown or grey fibres. It was used infrequently in certain products such as insulation materials and cement.

Actinolite: Actinolite asbestos is a less common type and can occur in various colours, including green, grey, or white. It can be found as a contaminant in some vermiculite products.

Health risks of asbestos exposure

Inhaling asbestos fibres can lead to various health problems. However, these health problems are not noticeable immediately and develop over time. Asbestos fibres are highly durable and can resist breakdown in the body, leading to longterm health risks even after exposure has ceased.

The development of asbestos-related diseases is influenced by factors such as the duration and intensity of exposure, the type of asbestos fibres encountered, individual susceptibility, and other factors like smoking. It is important to avoid inhalation of asbestos fibres and follow appropriate safety measures when handling asbestos-containing materials to minimise the risk of adverse health effects.

Respiratory health hazards: Inhalation of asbestos fibres is the primary route of exposure. These microscopic fibres, when airborne, can be easily inhaled and embedded in the lungs, leading to various respiratory issues.

Mesothelioma: This aggressive and incurable cancer affects the lining of the lungs, abdomen, or heart. It is primarily caused by asbestos exposure, often taking decades to manifest after initial contact.

Asbestosis: Prolonged exposure to asbestos can cause scarring of lung tissue, leading to a chronic and potentially debilitating respiratory condition known as asbestosis. Symptoms include shortness of breath, persistent coughing, and chest tightness.

Lung cancer: Asbestos exposure significantly increases the risk of developing lung cancer, especially in individuals who smoke. The combination of smoking and asbestos exposure compounds the risk exponentially.

Other cancers: Apart from lung cancer and mesothelioma, asbestos exposure has been linked to cancers affecting the larynx, throat, esophagus, stomach, colon, and rectum.

Environmental impact: Improper disposal of asbestos containing materials can lead to contamination of soil and water sources, posing risks to ecosystems and wildlife.

Secondary exposure: Those who come into contact with individuals working in environments contaminated with asbestos may also face secondary exposure risks due to the fibres being carried home on clothing, skin, or hair.

Long latency period: Diseases related to asbestos exposure often have a long latency period, meaning symptoms may not appear until many years after initial exposure, making it challenging to associate health issues directly with past contact.

What are the steps to avoiding asbestos?

Managing asbestos in buildings

Asbestos management plans are required for all buildings and they form part of the responsibility of the person who is maintaining or repairing a site or building. An asbestos management plan combines the building’s asbestos register, the plans of work and the working schedules.

It should include all details about monitoring and inspection of the building, the action plan for dealing with any asbestos, including the responsible person, and it should detail how anyone working on the site needs to be warned about potential or known asbestos, which is likely to be with warning signs and / or stickers in areas of concern. The management plan will also detail how workers working on the site will be informed of the building asbestos register, what it contains, and how they’ll be informed of the plan.

Why asbestos awareness matters

The risks associated with asbestos exposure are not merely historical anecdotes but present-day concerns impacting lives, health, and environments. However, armed with awareness, education, and proactive measures, we possess the power to mitigate these risks significantly.

By recognising the types and potential locations of asbestos, conducting thorough risk assessments, and implementing safe handling practices, you can pave the way for safer workplaces, homes, and communities.
