Massive credit goes to the window fitters, who displayed a high level of caution and responsibility by immediately stopping work when they discovered suspicious material hidden behind modern UPVC soffits. Their quick decision to halt the job and not disturb the material further was crucial in preventing the potential release of harmful asbestos fibres. Asbestos is a hazardous material that, when disturbed, can release fine fibres into the air, posing serious health risks such as lung cancer, mesothelioma, and asbestosis. In this case, their vigilance helped to avoid a potentially dangerous situation.

Once the suspicious material was identified, a bulk sampling analysis was conducted to determine if it contained asbestos. The results came back positive for both Amosite (brown asbestos) and Chrysotile (white asbestos). These two types of asbestos were commonly used in construction materials due to their durability and heat-resistant properties. The material in question was confirmed to be Asbestos Insulation Board (AIB), a high-risk asbestos-containing material (ACM) that is known for its potential to release large quantities of asbestos fibres if disturbed.

Given the hazardous nature of the material, immediate action was required. We arranged for an independent analyst to carry out personal air monitoring during the emergency clean-up and encapsulation work. Personal air monitoring involved measuring the concentration of asbestos fibres in the air in real time, ensuring that workers are not being exposed to dangerous levels of asbestos. This was a critical safety measure, especially during asbestos removal or encapsulation, to ensure that workers were protected throughout the process.

In addition to the personal air monitoring, a reassurance air test was conducted once all the work was completed. This test checked the air quality in the area to confirm that asbestos fibres were no longer present, ensuring that the space was safe for re-entry and use. The combination of these tests provided a comprehensive safety check, guaranteeing that both workers and future occupants would not be at risk from asbestos exposure.

This careful process of detection, monitoring, and clean-up highlights the importance of professional asbestos management and the diligence of the window fitters in this scenario.
