This report details a comprehensive hazardous substances assessment conducted at a laboratory facility in Cambridge.
The project aimed to evaluate occupational exposure to various potentially harmful chemicals used in DNA sequencing and related processes. The assessment involved air monitoring in key areas of the facility, including the Sanger Laboratory, NGS Laboratory, and Instrument Room. Personal and static monitoring techniques were employed to measure airborne concentrations of substances like ethanol and formaldehyde.
Overall, the results were encouraging. Exposure levels for all assessed substances were found to be below the established Workplace Exposure Limits. However, the report emphasises the importance of maintaining these low levels and suggests several improvements to further reduce potential risks. Recommendations include enhancing engineering controls, particularly for chemical waste disposal, maintaining and upgrading local exhaust ventilation systems, and implementing a health surveillance program for employees.
While the current safety measures appear effective, the report stresses the need for ongoing vigilance. It highlights the importance of regular monitoring, proper training, and continuous improvement of safety protocols to ensure a healthy work environment in this specialised laboratory setting.
