| Abstract |
The aim of this study was to measure dust exposure in tunnel construction work and to propose control measures. Personal exposures to total dust, respirable dust, and α-quartz were measured among 209 construction workers divided into eight groups according to the tasks performed. The mean values of exposure to total dust, respirable dust, and α-quartz for all tunnel workers were 3.5mg/m3, 1.2mg/m3 and 0.035mg/m3, respectively. 15% of the total dust measurements, 5% of the respirable dust and 21% of the α-quartz exceeded the Norwegian occupational exposure limits. Job groups with the highest exposure to total dust were shotcreting operators (6.8mg/m3), tunnel boring machine workers (6.2m3) and shaft drilling workers (6.1m3). The use of ventilated, closed cabs appeared to be the single most important control measure for lowering exposures. |
