Asbestos remediation work in the great green renovation

The research suggests that the data represents a "best-case scenario" as it was provided by inspectors engaged by clients that were “compliance-conscious and aware of the regulatory requirements”. In the UK, asbestos-related diseases take the lives of 20 tradespeople every week.¹ Left alone, the material is not harmful, but once disturbed or disintegrating, it can release asbestos fibres that infiltrate and progressively damage the lungs. The damage results in multiple health defects, such as the lung disease mesothelioma — a cancer that can take up to 20 years to develop, proving fatal within five years or less. 

As the latest report reveals how widespread asbestos still is, industry experts are growing increasingly concerned about the impact of energy renovations, since asbestos present in buildings could be released during renovation works planned to make homes more energy-efficient.

The European Green Deal strategy aims to double the rate of energy renovations by 2030 to tackle energy-related greenhouse gas emissions, but many buildings with a poor energy performance were constructed using asbestos. Accelerating the building renovation rate could significantly increase the number of people exposed to asbestos-related health risks, since asbestos present in buildings could be released during renovation works. As a result, the European Commission estimates that the number of workers at risk will increase by 4% every year for the next decade. 

Current data in the UK indicates that the risk of a fatal asbestos-related cancer is greatest among construction and engineering workers and the green renovation could make these trades even more vulnerable. However, asbestos does not only pose a threat to trade workers, but those they encounter, should invisible yet lethal asbestos particles stick to their personal protective equipment and tools. To help save lives while building a greener future, it’s vital that more people understand how to maximise asbestos monitoring accuracy to minimise risks.  

Industry expert, Tim Turney at occupational hygiene and workplace hazard monitoring expert Casella, shares best practice advice on asbestos monitoring, "Whenever asbestos is found and needs to be removed, it is a legal requirement to use licenced contractors and to ensure that strict regulations and guidance are followed to limit the potential release of dangerous, airborne fibres. The guidance typically includes personal air sampling and/or static air sampling, to ensure that there is no exposure during remediation work or during the cleaning and clearance processes at a removal site.  However, discrepancies in sampling and analysis procedures, limitations in personal protective clothing and insufficient cleaning before a clearance pass can hinder accuracy and increase risks.

"In the UK, a four-stage clearance process is used, involving a preliminary check of the site condition and job completeness, a thorough visual inspection inside the enclosure or work area, air monitoring and a final assessment of the post-enclosure or work area following dismantling. Licenced contractors may also take air samples before work is undertaken to establish a background level measurement. Conducting a test before disturbing any materials could save thousands of pounds on decontamination and environmental cleaning fees and help to avoid exposure. Additionally, trained professionals may take air samples during work on or near asbestos to confirm that there is no leakage from the enclosure.  Using remote methods to support sampling, such as Bluetooth and a mobile ‘phone app, will help to protect personal exposure safety while gathering the necessary measurements.
