Asbestos awl Health Questions I* MlKWIiPS ^ecen^ Public discussion of the health impli- U rtllUnUI II cations of asbestos dust has led to a number of erroneous and misleading impressions about hazards associated with the use of asbestos. These impressions are based on the unwarranted assump tion that data on occupational health risks associated with heavy, long term asbestos exposure can also be applied to the general public. The known medical facts, supported by nearly a half century of studies and research, are that: 1. Asbestos-related health risks are basically confined to the occupational and para-occupational setting. 2. Asbestos-related diseases may develop, generally, only after the inhala tion of substantial amounts of asbestos dust for a substantial period of time. 3. There is presently no evidence of hazard to the general public from ex posure to the piinute amounts of asbestos that may be present in com munity air. * Following are some Questions commonly asked about asbestos and health. Answers are based on known scientific evidence and industry experience. ls asbestos a fnajor air Qpollutant?

Q Should asbestos be banned until proven safe? Asbestos concentrations in both A the workplace and in commu nity air can be satisfactorily con trolled, and there is therefore no reason to ban the use of any as bestos-containing product. From a public health standpoint, such bans are completely unnecessary and would serve only as meaningless gestures. To what extent is asbestos an Qoccupational health hazard? Because of the long latent A period of asbestos-related dis ease, some cases are still devel oping among long-term employees whose exposure began at a time when little was known of the amount of asbestos a human being could tolerate, and when the dust control equipment in use was not . as efficient or as sophisticated as it is today. With present medical knowledge and today's improved dust control measures, however, there is every reason to believe that these cases will decrease in the future and asbestos-related disease will cease to be a major occupational problem. QCan asbestos be used safely in the workplace? Asbestos fiber can be handled A and used on the job with com plete safety so long as certain basic precautionary measures are fol lowed. These include careful han dling of fiber bags to prevent tear ing and spilling, the use of dust control exhaust hoods at all stages of in-plant handling where dust is unavoidably created, the wearing of respiratory protective equip ment where necessary, and good housekeeping with regard to dust clean-up and disposal procedures. Q Shouldn't substitutes for asbes tos be used whenever possible? More is known about the poten A tial health hazards of asbestos and the proper means for their control than about materials that might be used to replace asbestos. It would be unwise to substitute unproven materials whose health effects are unknown for asbestos, which has demonstrated its use fulness to society over the past century. For many essential, life saving uses, asbestos is the only material that can do the job. What is industry doing about Qthe problem? The asbestos industry, starting A in the late 1920's, sponsored some of the first studies of as bestos-related disease ever under taken in the United States. These studies provided information that became the basis for dust control programs in the industry, which have been improved and expanded over the years. Tens of millions of dollars in sophisticated and effi cient equipment and techniques have been devoted to preventing the inhalation of asbestos dust by workers in the mining and milling of asbestos and in the manufacture of asbestos-containing products. Through the Institute of Occupa tional and Environmental Health in Montreal, the Industrial Health Foundation in Pittsburgh, and se lected hospitals and universities, the industry is sponsoring or co operating in major epidemiological and other research projects de signed to identify and eliminate as bestos-related health risks within the industry, and also for fabrica tors and applicators of finished asbestos-containing products.
