[Objective] To evaluate fatigue levels among stone carving workers. [Methods] An occupational hazards survey was carried out in a stone carving plant, and the labor intensity and the fatigue degree of occupational workers(n=50) and control workers(n=40) were evaluated. [Results] The concentrations of dust were 23.33-125.33 mg/m3, and respirable dust accounted for 66.0%-78.9% of total dust. The 8-hour equivalent continuous A-weighted sound pressure levels were 90.0-104.0 dB(A). Stone curving work was identif...
