什么是爆炸極限？

作用：時(shí)刻控制好可燃物的濃度，不要讓其達(dá)到“爆炸極限”。一旦發(fā)生爆炸千萬(wàn)不要圍觀。

2015年在我國(guó)臺(tái)灣地區(qū)新北市游樂(lè)園發(fā)生的粉塵爆炸事故造成多人死傷，讓人恐慌。游樂(lè)園之所以變成煉獄，是因?yàn)槿藗冊(cè)诨顒?dòng)中噴撒的玉米粉與空氣混合后形成了一定濃度比例，此時(shí)遇到了火花馬上發(fā)生爆炸。
“爆炸極限”表示的正是“可導(dǎo)致爆炸的濃度范圍”?？扇嘉镔|(zhì)與空氣必須在爆炸極限內(nèi)均勻混合，遇著火源才會(huì)發(fā)生爆炸；在低于爆炸下限時(shí)不爆炸也不著火；在高于爆炸上限時(shí)不會(huì)爆炸，但能燃燒。
不同物質(zhì)爆炸極限并不一樣。事發(fā)也非常突然，粉塵類的爆炸更容易讓人忽視，比如鋁粉、鋅粉等。各種塑料粉末、小麥粉、奶粉、煤塵、植物纖維等生產(chǎn)加工場(chǎng)所很容易發(fā)生粉塵爆炸，因此要時(shí)刻控制好這些場(chǎng)所的可燃物濃度，保障安全生產(chǎn)。爆炸撲救需要時(shí)刻注意可燃物的爆炸極限，因?yàn)槿f(wàn)一撲救時(shí)操作不當(dāng)，可能產(chǎn)生多次爆炸造成更大的傷亡。遇到此類爆炸，切記千萬(wàn)不要圍觀！
