| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 98 === According to the related statistics, the construction workers in Taiwan constantly suffer physical disorders or injuries due to heavy workload and excessive working hours. As a matter of fact, tolerable working hours are related to oxygen consumption required at work and individual’s ability in oxygen consumption. Factors such as working habits, environment or climate cause variations in oxygen consumption of construction workers required at work in different countries. Not many studies on the above aspect have been carried out for the construction industry in Taiwan so far. Therefore, this study attempts to survey oxygen consumption at work based on the work types commonly seen in the construction industry in Taiwan. In addition, the information of energy metabolism versus general work types executed by the workers in the construction industry is established as a reference for the management personnel in the industry in order to make proper arrangements of break time and operation time for workers, prevent workers from excessive fatigue which leads to accidents, and maintain good operation efficiency.
The measurements in this study were carried out at a construction site. 14 workers in the construction industry in Taiwan were invited to participate in the experiment. The work types surveyed were: formwork assembly, grouting, water and electricity distribution, tile pavement, sand shoveling, lay out and rough manual works. START 2000M portable gas analyzer was applied to measure oxygen consumption at work. Then, the software, Ergo 2000M, was used for further analysis. The analytical results showing the average oxygen consumption required at work are as follows: formwork assembly: 1.25±0.19 (L/min); grouting: 1.17±0.24(L/min); water and electricity distribution: 0.92±0.20(L/min); tile pavement: 0.52±0.12(L/min); sand shoveling: 1.49±0.46(L/min); lay out: 0.89±0.17(L/min); as well as rough manual works: 1.01±0.17(L/min).
