防火防爆是气焊与气割安全工作的重点

[ 2011-7-26 15:32:00 | By: 杨远锋 ]

首先，气焊与气割所使用的介质如电石、乙炔等的燃爆危险性都很大，而且同时存在氧气，一旦遇到火源，很容易发生燃烧爆炸。其次，乙炔发生器是容易发生着火爆炸的设备。一旦发生回火，乙炔胶管和氧气胶管也可能发生着火爆炸。再次，在存有可燃爆炸性混合气体和其它易燃物的场所，气焊火焰及气焊时产生的火星、熔珠和熔渣都有可能成为火灾爆炸事故的点火源。乙炔--氧气火焰温度为3100～ 3300℃，较大的熔珠和熔渣能飞溅到距操作点 5米以外的地方，如遇到可燃爆炸性混合气体或可燃易燃物品，就可能发生火灾爆炸事故。所以说，火灾和爆炸是气焊的主要危险，防火与防爆是气焊与气割安全工作的重点。
