In this study, we selected the FRP process (Fiberglass Reinforced Plastics) conducted in the lower deck of a yacht for investigations. Seven tasks of this FRP process, including the lamination, lay-up dry fibers, vacuum, infusion, dismantle, strengthening, and machinery arrangement were chosen to measure the TVOC (Total Volatile Organic Compound) concentration using PID (Photoionization Detector's), and concentrations of each VOC (Volatile Organic Compound, VOC) were first collected by a stainless canister, and then analyzed using a GC/MS (Gas Chromatography-Mass Spectrophotometer). The results show that acetone and n-Dodecane were the highest and lowest concentration during the lamination, vacuum, infusion, dismantle, strengthening, and machinery arrangement processes. The concentration of TVOC in the infusion process was the highest (40.1x104 ppb), the vacuum process was the lowest (1.23×104 ppb). The total exposure found above the permissible exposure limit was in the lamination process which was the highest. To control the total exposure below the permissible exposure limit for each work task, the PID value should be control between 42.0 to 1,768 ppm. In conclusion, the developed methodology is applicable to conduct and manage exposure risk assessment for the yacht manufacturing factory workers. Perny-Jy Tsai 蔡朋枝 2012 學位論文 ; thesis 116 zh-TW |
