各种场所中的有毒气体的确认一般是根据它们对于暴露在现场的工人的生理上的影响,也就是我们通常所说的毒性来分类的:毒性=气体浓度×暴露时间,由此可见,由于各种有毒有害气体的毒性是一个定值,浓度和时间就成为衡量有毒气体危害的重要参数。气体浓度越大,允许工人停留的时间也越短。 The identification of toxic gases in various locations is generally based on their physiological effects on exposed workers, that is, what we commonly refer to as toxicity: Toxicity = Gas Concentration × Exposure Time, from which it can be seen that due to Toxicity of various toxic and hazardous gases is a set value, concentration and time has become an important parameter to measure the harm of toxic gases. The greater the gas concentration, the shorter the time allowed for workers to stay.
