[Measurement of airborne asbestos fibers on railroad rolling stock].

In February 1995 the Italian Railways Health Department set up a special study group in order to assess the effectiveness of the measures adopted against hazards due to the presence of asbestos in rolling stock currently in use on the rail network. The group set up specific procedures for sampling and analysis, on the basis of the criteria fixed for civil buildings in Ministerial Decree of 6/9/94, which was subsequently applied to rolling stock by Ministerial Decree of 26/10/95. In accordance with these procedures the study group carried out environmental studies via test runs programmed by the Railways Technical Departments, on trains made up of different types of vehicles. Insulated, completely or partially deinsulated and originally non-insulated vehicles were studied. Samples were analysed via scanning electron microscopy (SEM) with elementary dispersion X spectroscopy (EDXS) carried out by highly qualified public laboratories (ISPESL--National Institute for Prevention and Work Safety, ARPA--Regional Environmental Protection Agency, CRA--Veneto Region, University Departments). Altogether, from the start of the programme up to September 1998, 1464 samples in 170 test runs on 619 rolling stock vehicles were examined. These involved 83 locomotives, 83 electric rail-cars and 453 carriages. The results showed that in over 99% of the samples the fibre concentrations were below 2 fibres/litre, which is the value fixed by law for buildings and rail vehicles in order to qualify for effective decontamination status. Values exceeding 2 fibres/litre were found in only 4 vehicles, which were withdrawn or blocked for further checks. As a precaution, 18 vehicles where concentrations over 1 but less than 2 fibres/litre were found, were also blocked and their return to service has been postponed for further checks and analyses until the results show concentrations below 1 fibre/litre. Environmental analyses carried out up to the present indicate an overall situation comparable to that usually found in the general environmental without any asbestos dispersion sources. Surveillance and investigations are still under way in order to achieve the aims of the safety programme set up by the Italian Railways to ensure health and environmental protection.

[Real problems of conducting social-hygienic monitoring on railroads].

Sociohygienic monitoring on the railway transport, which is a branch part of the state sociohygienic monitoring system, includes observation, analysis, assessment, and prediction of the health status and habitat of railway workers and population to be served, as well as the establishment of associations of the health status with environmental factors. Standard legal, scientific-and-methodological, and organizational bases have been set up for branch monitoring. The basic parameters and the procedure for interaction of branch and territorial entities have been defined.
