The effect of differing concepts of the criteria that should be used for the diagnosis of asbestos disease.

The work of the Society for the Prevention of Asbestosis and Industrial Disease suggests that arbitrary rules, operated for the purpose of deciding which cases may benefit from employment insurance schemes, are adding to the recognized problems connected with the diagnosis of asbestos disease. As a result, statistics are unrealistic and do not include cases which show not only that workers in th asbestos manufacturing industry are at risk, but that asbestos, including chrysotile, affects the health of the community.
