此讲谈谈通风防护。有毒气体怎样引起人体中毒有毒气体或蒸气可存在于生产过程的各个环节,吸入人体后能产生不同程度的危害,引起慢性中毒或急性中毒。但并不是说人体一遇到有毒气体或蒸气一定会发生中毒现象,而是要看有毒气体的毒性、在生产环境空气中的浓度、接触的时间长短以及环境温度、湿度和各人身体健康情况而定。一般来说,有毒气体毒性越大.在空气中浓度越高,人体接触时间越长,以及环境中温度高,湿度大,则机体中毒
This talk about ventilation protection. How poisonous gases cause human poisoning Toxic gases or vapors can exist in all aspects of the production process and can cause varying degrees of harm after inhalation and cause chronic poisoning or acute poisoning. However, it does not mean that the poisoning of toxic gases or vapors must occur in the human body. It depends on the toxicity of toxic gases, the concentration of air in the production environment, the length of exposure, and the ambient temperature, humidity and physical health of each person And set. In general, the toxic toxic gas greater the greater the concentration in the air, the longer the contact time of the human body, as well as the environment temperature, humidity, the body poisoning
