第五章 討論
第二節 建議
第一項 法規容許濃度標準
許多先進國家目前均對結晶型游離二氧化矽進行管制，我國亦不
83
例外，但目前世界上只有我國、美國OSHA 與印度以計算公式進行 結晶型游離二氧化矽的管制，其餘國家均以一定值進行管控，且有越 來越嚴格的趨勢。若以定值進行暴露濃度的管控，業者與相關主管機 關對於結晶型游離二氧化矽法規容許濃度便可更加明確，因此可以建 議我國相關機關可以依循目前世界潮流，作法規容許濃度管控的修 正。
第二項 作業環境檢測
我國粉塵作業環境依勞委會之規定須以每六個月進行作業現場 之檢測，但目前檢測均以空氣中粉塵代表環境中結晶型游離二氧化 矽，故本研究建議未來須強制要求應以實際測量之結晶型游離二氧化 矽進行管控。
第三項 作業環境改善
(1) 因鑄造廠作業環境廣大，且許多作業項目之位置無法明確區 分，若要施以整體排氣裝置難以解決其當前問題且成本過 高，不符合效益原則。因此建議可以在磨毛邊區與拆模作業 區域進行局部排氣之設備，以降低勞工暴露結晶型游離二氧 化矽之濃度。
(2) 作業環境現場可以以加濕作業，減少作業環境中揚起的粉塵
84
量，以減低勞工暴露結晶型游離二氧化矽的含量。
第四項 勞工教育訓練
(1) 進行勞工安全衛生教育訓練，使勞工更瞭解結晶型游離二氧
化矽的危害如何安全操作、儲存結晶型游離二氧化矽。
(2) 宣導正確的工作操作技術、工程控制技術與個人防護具的正
確使用方式，使勞工可以瞭解保護自己的重要性。
(3) 個人衛生的教育訓練，進行作業環境中個人衛生的教育訓
練，避免員工在作業環境中抽菸與飲食，以降低結晶型游離 二氧化矽吸入或食入。
第五項 行政管理
(1) 依照我國作業環境測定實施辦法規定，應每半年或作業環境 條件改變時由勞委會指定之作業環境測定機構與認可實驗 室進行粉塵濃度的測定，並訂定作業環境測定時施計畫，以 發生源或暴露勞工數進行採樣策略的擬定。其結果依規定項 目紀錄並保存十年。
(2) 從事粉塵作業者依照我國勞工健康保護規則規定，每年須實 行特定項目特殊體格檢查，並將檢查紀錄保存十年。
