Abstract
Environmental survey for determination of employee exposure to fluorides, cyanides, hydrochloric-acid (7647010), and tin (7440315) from electroplating solutions at the electrolytic tinning line, with measurement also of exposure to excessive noise. The threshold limit value for toxic substances is exceeded in one case; and noise is excessive in two cases. Recommendations are made for more effective location of controlled exhaust ventilation and for the plating solution mixing process, use of Bureau of Mines approved respirators in preparation of chemical solutions, elimination of noise at source, provision of hearing protection and audiometric examinations until noise is reduced, and continuing effort at good housekeeping and plant maintenance.
