Silica Dust Exposure Testing in Construction Sites
In construction sites where activities like cutting, grinding, drilling, and abrasive blasting are carried out, silica dust exposure can be a significant occupational health risk. This service focuses on the critical task of monitoring and assessing silica dust levels to ensure compliance with stringent safety regulations.
The primary goal is to protect workers from Silica (SiO₂) dust inhalation, which can lead to severe respiratory diseases such as silicosis, lung cancer, and chronic obstructive pulmonary disease. This service includes the collection of air samples, analysis using advanced analytical techniques, and providing actionable insights that help in implementing effective control measures.
The service is particularly relevant for sectors like construction, stone masonry, brickworks, and road building where the risk of silica exposure is highest. Compliance with international standards such as OSHA (OSHA 1926.55), ACGIH (TWA-Permissible Exposure Limit: 0.05 mg/m³) ensures that employers are meeting legal requirements while also safeguarding worker health.
The service involves the use of state-of-the-art sampling equipment and analytical methods to ensure accurate measurement of silica dust levels. The process begins with the collection of air samples using a cyclone sampler or a high-volume air sampler, which captures airborne particles down to 10 microns in diameter. These samples are then analyzed using X-ray fluorescence (XRF) spectrometry, which is capable of detecting even trace amounts of silica.
The analysis process involves several stages: sample collection, preparation, and digestion followed by instrumental analysis. The results provide detailed information about the levels of respirable crystalline silica in the air, helping employers to identify high-risk areas and take corrective actions promptly.
Our service ensures that every aspect of the testing process is conducted in compliance with relevant standards such as ISO 13568-2:2019. The results are presented in a comprehensive report that includes recommendations for reducing silica exposure, which could range from engineering controls to administrative measures.
Understanding the importance of this service, we offer tailored solutions to meet the specific needs of our clients. Our team of experts can help you identify potential risks and implement strategies to mitigate them effectively. By partnering with us, you not only ensure compliance but also contribute to a safer working environment for all your employees.
