冷冻加工厂内主要有害因素是冷冻机内用于作制冷剂的氨,低温及噪音。通过52家冷冻厂调查:冷冻机房内空气中氨的浓度在2至10mg/m~3,平均为18.5mg/m~3,少数厂家空气中氨的浓度严重超标,甚至超过国家标准的2倍多,这严重影响操作工人的身体健康。从冷库内的温度测定结果是:库温在-8.5～-23℃,平均为-15.05℃,在这个温度下就难以使水产品长期保鲜,势必影响冷冻水产
The main harmful factor in the freezer is the ammonia, low temperature and noise used in the freezer as a refrigerant. Through the investigation of 52 refrigeration plants, the concentration of ammonia in the air in the freezer was between 2 and 10 mg / m 3, with an average of 18.5 mg / m 3. The concentration of ammonia in the air of a few manufacturers exceeded the standard even twice as high as the national standard More, which seriously affect the health of workers. From the cold storage temperature measurement results are: the library temperature at -8.5 ~ -23 ℃, an average of -15.05 ℃, at this temperature is difficult to make long-term preservation of aquatic products, will inevitably affect the frozen aquatic products
