B. Sobree I would agree that 1 a sufficient need has developed for facilities within the Du Pont Company for the collection and counting of dust samples containing asbestos fibers 2 the search for substitute materials should be a continuing one and 3 another Company conference would be worth- Some of our recent experiences are pertinent In response to inquiries from several plants we have sent out a trained industrial hygiene engineer to make a survey at the plant in company with the plant technical persons who expect to have the continuing responsibility for monitoring airborne asbestos concentrations Our industrial hygienist usually spends one or one and half days at the plant He examines ' 1 the processes in which containing materials are used 2 the facilities for handling it including those for dust control enclosure wetting exhaust ventilation dust collection 3 the medical surveillance of potentially exposed persons In company with the plant technical people he collects samples of airborne locating sources of dust leaks from equipment and also determines the concentration in workers breathing zones He studies and observes factors which influence or affect airborne dusi cunecutrations and the effectiveness of control procedures He offers recommendations for improved dust control or protective measures if such are seen to be necessary ' He works out with the plant technical people a systematic procedure and schedule for periodic air sampling , R.
