Ansaldo Breda’s plant in Reggio Calabria had already been significantly remediated in 2001. In the framework of the workers' health protection programme, the danger due to exposure to any remaining asbestos fibres was taken into account. Analysis of a number of samples of deposited dust detected asbestos fibres in some of them. Air analyses, to detect airborne asbestos fibres, produced negative results. The most probable reason for the presence of asbestos in the powders is the replacement of the Eternit asbestos roof sheets, done 15 years ago.
The company decided to have TIA perform the special clean-up to remove the asbestos-contaminated dust, during the summer production downtime.
