RT Journal Article SR Electronic T1 Extreme airborne asbestos concentrations in a public building. JF British Journal of Industrial Medicine JO Br J Ind Med FD BMJ Publishing Group Ltd SP 486 OP 488 DO 10.1136/oem.49.7.486 VO 49 IS 7 A1 Ganor, E A1 Fischbein, A A1 Brenner, S A1 Froom, P YR 1992 UL http://oem.bmj.com/content/49/7/486.abstract AB Fibre concentrations of asbestos were measured in the air of a communal dining room in which the damaged ceiling had a sprayed on coating of insulation containing asbestos. The average concentration of crocidolite asbestos fibres was 4 f/cm3, 20 times the highest air concentration that appears to have been reported previously for a public building. It is concluded that although air concentrations of asbestos fibres in public buildings containing asbestos insulation materials are usually low, high concentrations can occur. This may have implications for the risk of exposed persons developing diseases associated with asbestos.
