有机溶剂三氯乙烯工业上常用于金属除油,其毒性较大,如果防护不好,可经呼吸道、消化道和皮肤吸收而引起急性或慢性中毒,主要作用于神经系统。严重急性中毒可以引起呼吸麻痹,心跳停止造成接触者突然死亡。西安机务段便用三氯乙烯为各种部件除油,工人屡有各种反应,而且邻近车间班组也有相同不良反应。为了摸清危害情况,77年5月、9月两次连续测定空气中三氯乙烯浓度扩散情况,并对直接接触和不直接接触的工人进行三氯乙烯吸入后尿中分解物的检验分析。结果证明其危害情况较大,现就调查资料讨论分析,以引起重视劳动条件改善。一、生产工艺及防护概况西安机务段每月平均架修机车16台。拆卸下的
Trichlorethylene, an organic solvent commonly used in industry, is highly toxic to metals and can cause acute or chronic poisoning through absorption through the respiratory tract, digestive tract, and skin if it is not well protected. It acts mainly on the nervous system. Severe acute poisoning can cause respiratory paralysis, cardiac arrest caused by the sudden death of the contact. Xi’an Locomotive Depot will use trichlorethylene for oil removal of various components, workers often have a variety of reactions, and the workshop team also have the same side effects. In order to find out the hazard situation, two consecutively measured concentrations of trichlorethylene in air were continuously measured in May and September of 77, and the urinary decomposition products were inspected and analyzed after inhalation of trichlorethylene by direct and indirect contact with workers. The results prove that the damage is greater. We are discussing and analyzing the survey data to draw attention to the improvement of working conditions. First, the production process and protection Overview Xi’an locomotive repair section on average 16 units per month. Disassembled
