酸洗作业工人不可避免地接触到某些酸类溶液,这些酸类溶液又不可避免地产生酸雾或溅到操作工人的身上、手上和脸上:在防护设备不健全的作业环境中工作,又不可避免地损害工人的呼吸道,引起气管和肺部的疾病,或是造成手、脸上的烧伤。这种直接操作的旧方式,每时每刻都在危害着操作工人的身体健康,必须加以改进。 Pickling workers inevitably come into contact with certain acid solutions that inevitably generate acid mist or splashes on the workers, hands and face of the operator: working in an unsafe working environment , Inevitably damage workers’ respiratory tract, cause trachea and lung disease, or cause hand, face burn. This old method of direct operation, every moment, jeopardizes the health of the operating workers and must be improved.
