An industrial hygiene survey was conducted at the International Minerals and Chemical Corporation, Phosphate Chemical Complex, New Wales, Florida, on June 7-11, 1976 as part of the industry-wide study of the phosphate fertilizer industry (SIC-2874). Exposures which may occur routinely are sulfur-dioxide (7446095), sulfuric- acid (7664939) mist, phosphoric-acid (7664382) mist, ammonia (7664417) and radon (10043922) daughters. Additional exposures from maintenance operations or upset conditions include: vanadium- pentoxide (1314621), heavy metals, uranium (7440611), fluoride and silica (7631869). Recommendations are made to reduce exposure; these include the use of personal protective equipment and regular checks of the acid and ammonia lines.
