The asbestos industry and statutory control of its hazards.

The difficulties of balancing the possible hazards of asbestos against its useful properties, the cost of control measures and the availability of adequate substitutes are described. The history of the asbestos industry, of recognition of the association between asbestos and respiratory disease and of the develpment of control regulations in the UK are outlined. The present provisions for inspection of work places, for medical services to workers and for environmental control within and outside the workplace have been reviewed and a Health and Safety Commission set up to implement them; their work is described. Although the regulations are being implemented, however, public anxiety has increased. Justification for such anxiety comes from reports of still-existing hazards and from the fact that the current standard was established on faulty grounds. Three studies are described which indicate that a dose-response relationship may exist in relation to the carcinogenicity of asbestos; however, there is still not enough evidence to set standards. Further studies have shown that the different types of asbestos incur different degrees of risk. The UK Asbestos Standards are thus undergoing revision, this time in consultation not only with physicians and hygienists, but also with members of industry, trades union members, academics and local authorities.
