||Report of a study of 11 car-wash installations to determine: the level of exposure of workers to solvents (white spirit containing mainly aliphatic but also some aromatic hydrocarbons); and the effectiveness of the ventilation systems. Concentrations measured varied widely due to differences in both the efficiency of the ventilation systems and the type of vehicle being washed. The average concentration in the breathing zone was 160mg/m3 (range of 5-465mg/m3) when private cars were being washed; for lorries the corresponding figures were 270mg/m3 and 45-685 mg/m3. The average exposure was below the recommended limit of 770mg/m3. However, peak concentrations were as high as 4,500mg/m3. Average airflow during car washing was 1.3m3/s. Ventilation was most efficient when make-up air was blown down from the ceiling and exhausted near floor level.
