可燃气体达到爆炸极限如甲烷、一氧化碳等，在空气中，甲烷在空气中爆炸范围为5% ～15%,氢气的爆炸极限4%-70%左右，一氧化碳的爆炸极限为12.5%—74%。；窒息或有毒气体的浓度都有标准，如人体耐受二氧化碳浓度的极限为6.55%。 正常空气中二氧化碳浓度为0.03%～0.04%,国家规定公共场所二氧化碳浓度的卫生标准是0.1%；CO毒性很大，正常人接触1小时为35ppm，不会有明显中毒症状，但超过就会中毒，严重会死亡。一氧化炭不超过24PPM，含氧量不低于百分之二十
煤矿安全规程规定如下：
井下空气成分必须符合下列要求：
（一）采掘工作面的进风流中，氧气浓度不低于20%，二氧化碳浓度不超过0.5%。
（二）有害气体的浓度不超过表1规定。
表1 矿井有害气体最高允许浓度
名称 最高允许浓度(％)
一氧化碳CO 0.0024
氧化氮(换算成二氧化氮NO2) 0.00025
二氧化硫SO2 0.0005
硫化氢H2S 0.00066
氨NH3 0.004
瓦斯、二氧化碳和氢气的允许浓度按本规程的有关规定执行。
矿井中所有气体的浓度均按体积的百分比计算。
