碩士 === 國立屏東科技大學 === 環境工程與科學系所 === 99 === With 1500 ℃flowing steel water and 1000 ℃stacked slabs within the plant, the crane operator at the top of the steelworks plant is exposed to high temperature operation environment. The main objective of this research was to protect the steelworks crane operator from thermal hazard. The major ways to do this were to enhance heat convection within the plant, to reduce thermal radiation, to reinforce the thermal insulation in the crane operator room, to enhance high temperature air conditioning system, etc. After the improvement measures were done, the indoor plate temperature was reduced from 66 ℃ to 56 ℃, the Wet Bulb Globe Temperature (WBGT) was reduced from 33.0 ℃to25.0 ℃, and the peripheral temperature of the crane operation room was kept the same at 70 ℃, under the 29 ℃,atomosphere temperature. The operating environment for the employee was significantly improved. In addition to the engineering measures, the setup of reasonable duty-shift system, appropriate high temperature protection tool provision , and appropriate water intake were highly recommended . Through all the above actions, the mental and body health of the operator can then be protected.
