Title Asbestos exposure in a steam-electric generating plant
Bibliographic information Dec. 1993, Vol.37, No.6, p.645-653. 22 ref.
Abstract A study on asbestos risk in an old multi-fuel-fired steam electric power station showed that in spite of the presence of large amounts of asbestos-containing materials, the mean airborne concentration of asbestos was as low as 1.55 fibres/L under normal operating conditions. Much higher concentrations may obviously occur during maintenance or renovation operations. Man-made mineral fibres (MMMFs) were detected only occasionally in samples. Three non-consecutive sputum samples were collected from all 521 workers included in the study: 3.1% of the samples contained asbestos bodies (ABs) (less than four ABs per g of sputum). Small opacities were present in 15 out of 470 radiogrammes of acceptable quality (3.2%). No ABs were found in these cases. Pleural changes were less common (10 cases). Two out of 5 bilateral cases had ABs in the sputum. Repeated AB counts in the sputum is considered as being more useful than the search of pleural abnormalities by traditional postero-anterior (PA) view in detecting signs of low asbestos exposure.
