Man-made mineral fibre boards in buildings--health risks caused by quality deficiencies.

The Institute of Hygiene was requested to determine causes and scope of health complaints made by the employees of Haldensleben district administration after sound absorbing mineral fibre boards had been installed as suspended ceilings. The boards were coated with a lean water-carried paint; however, the edges, which were partially frayed, were not coated. The air inside the rooms was measured on all four storeys of the building, followed by scanning electron microscopy in compliance with VDI Code 3492.
