Sysco Environmental Ltd conducted an indoor air quality survey at the Uxbridge Public Mortuary, located on Kingston Lane, Uxbridge, following staff complaints regarding odours. The primary objectives were to assess the atmospheric concentrations of formaldehyde and sulphuric acid mists within the working environment and to determine the daily personal exposure levels for employees. The survey included a comprehensive inspection of the premises, identification of high-risk areas, and collection of samples for laboratory analysis. The results indicated that exposure levels were well below the assigned workplace exposure limits. Recommendations included necessary repairs to the air management system to improve odour control and ensure ongoing compliance with health and safety regulations.
