Sysco Environmental Ltd conducted a property inspection and historic plaster sampling on the caretaker's property of an old school in Sheffield. The historic school building, unoccupied for over a decade, is being redeveloped into a new community space. The survey focused on a two-storey, partially dilapidated property, aiming to assess the extent of historic plaster containing animal hair. Comprehensive visual inspections and sampling of suspected plaster were performed, although some areas were difficult to access and presumed to contain historic animal hair plaster. Samples analysed by the UKAS accredited Rare and Imported Pathogens Laboratory revealed no presence of historic plaster with animal hair, and Bacillus Anthracis was not detected. Therefore, no further actions are required regarding historic plaster in this property. All health and safety protocols were strictly adhered to, ensuring minimal risk to future occupants and visitors.
