11、 Page: 4of 4 Date: 00-01-10 Appendix I Chinese translation of Section 6 6.1 廠房工程的技工應每六個月進行全廠的噪音評估一次。6.2 量度程序6.2.1量度噪音之前和之後,聲級計的聲響性能都需要用電聲式校準器(94dB)來檢查,準確度最少為0.5分貝。6.2.2 積分式聲級計應調校“快” (F)反應上。6.2.3傳聲器通常應放置於地面約1.5米處,以直臂把持以避免反射和堵塞從一些方向來的聲音。6.2.4 量度時間應為 30秒。6.2.5在戶外量度時,必須使用擋風波來減低風聲,塵埃和濕度的效應。6.2.6量度噪音的單位是 Leq,應在不少於 4個可代表位置及平均地分佈於測試的地區,聲級應加以平均,以取得地區的水平。所有量度記錄應填寫在噪音評估報告QKW-666-EMS0020 表格一內。6.2.7廠房工程的技工應將完成的噪音評估報交回EMS主任。6.3如發現噪音超過 85分貝( A),廠房工程的技工應填寫環境污染報告及將完成後環境污染報告交給 EMS主任。6.4EMS主任調查引致噪音的原因及根據程序 QKW-666-EMS0004 來跟進改善行動。6.5 EMS主任負責保存噪音評估報,環境污染報告及程序來跟進改善行動五年。
