Environmental samples of airborne dust were taken and workers were examined at the Licons, Lithium-carbonate and Pyrobor facilities at Kerr-McGee Chemical Corp. (SIC-2819) in Trona, California on June 21 and 22, 1977. An evaluation request came from the Chemical and Processing Workers Union Local 35, Trona, California on behalf of approximately 50 affected workers to determine whether lithium- carbonate (554132) (Li2CO3) and anhydrous-borax (1330434) were hazardous in the concentrations found at the facilities. Blood and urine tests and medical examination results were generally negative. The authors conclude that exposures to Li2CO3 and borax do not present a health hazard, but dust exposures to crystalline- tetraborate (12258536) are excessive. They recommend the use of personal protective equipment, good work habits, worker education and an engineering survey.
