Cherniack, M; Lewis, F

There was concern that workers at the Ridgway Color Company were experiencing an unusually high rate of death from cancer. This concern was compounded by the identification of 3,3'-dichlorobenzidine (DCB) as a suspect carcinogen by OSHA, since DCB had previously been handled in the plant as a benign chemical intermediate. Urine samples were also collected to detect any presence of DCB. The environmental evaluation consisted of (1) area and personal air sampling for DCB, hydrochloric acid (HCL), and total dust, (2) analysis for trace contamination with potential carcinogens in bulk samples of pigment intermediate, (3) analysis of diarylide yellow presscake for DCB, and (4) a characterization of ventilation and work practices.
