本研究係利用資料庫系統與其他相關搜尋網站查詢篩選出全國可能有低溫作業環境之工廠，再透過郵寄問卷與電話訪問方式進行工廠現況調查，問卷內容包括：(一)事業單位概況；(二)製程、原物料與主要產品；(三)低溫作業情形；(四)作業勞工健康檢查實施情形；(五)勞工相關症狀等五大部分。經由回收問卷的數據分析發現，如依據低溫作業型態來分類，國內以冷凍水產類的工廠最多，其次為冷凍調理食品與冷凍肉類的加工廠且分佈多數集中於南部地區。在這些具有低溫作業環境的工廠中，同時有冷暴露與冷接觸者佔最多(38.5%)，其次為只有冷暴露者(34.6%)，接著是僅有冷接觸者(26.9%)。暴露環境之溫度分佈集中於未滿-18 ℃的冷凍庫房，以及介於10 ℃以上未滿18 ℃之溫度範圍的冷凍肉品加工廠。低溫作業環境從業員工主要發生的症狀以手腳冰冷(21.1%)、手腳麻木(14.1%)、呼吸道疾病(12.9%)與容易疲倦(10.6%)為主。

The workplaces with cold environment were screened from database to investigate (1) a profile, (2) manufacturing process, raw materials and products, (3) state of cold environment, (4) medical examination and (5) cold related symptoms by questionnaire and telephone interview. Extensive workplaces with cold environment were found in aquatic products industry, frozen food processing and meat processing factory, and most of them were located in southern Taiwan. It was found that 38.5 % of cold environment exist both cold air exposure and cold touch among the workplace investigated. In addition, 34.6 % workplace showed cold air exposure only, and 26.9 % were referred to cold touch only. Most of the cold workplaces were found in cold storage warehouse with temperature lower than -18 , and in frozen me℃at processing industry with temperature ranging between 10 and 18 . The major symptoms or diseases for the workers ℃℃in the cold environment are coldness of hand or leg (21.1 %), numbness of hand or leg (21.1 %),respiratory diseases (21.1 %) and feeling of tired (10.6 %).
