黃光環境暴露色彩辨識探討

The study of color discrimination in yellow lamp environment

本研究採用 Farnsworth-Munsell 100-Hue test 模擬半導體業黃光區之作業人員色彩辨識。研究的方法是在實驗室中各安裝 4 盞 40-watt 日光燈及黃色螢光燈，由 40 位大學生接受辨識力測試，並利用一因子重複測量設計評估受試者平均辨識力差異之顯著性。研究結果發現在不同光源下，受測者之顏色辨識能力會產生明顯差異(P<0.001)。受測者在黃光環境平均錯誤分數遠大於白光環境，其次，在黃光環境，對於黃綠、綠、藍綠、藍色、紫色及紅色等會有較差的辨識能力。本研究建議在黃光作業區域，緊急設施的設計上，應以其他符碼來取代色彩作為辨識的依據，以便於迅速的辨認與反應。

This study uses the Farnsworth-Munsell 100-Hue test to simulate the real world color discrimination in lithographic area of the semiconductor industry. The approach is to set up four 40-watt white and yellow incandescent lamps separately in a laboratory. Using one factor repeated measures design, 40 university students were subjected to the test and the data analyzed. The results showed that the color discrimination ability of the subjects is significantly different at α=0.05 by MANOVA test (P <0.001). The average mistake score at yellow lamp is higher than that in white light. The color discrimination ability decreases at yellow-green, green, blue-green, blue, purple and red under yellow lamp. From above results, it is recommended that the emergency facilities design should be substituted with other codes in lithographic area in order to have a rapid identification and response.
