1.If ignition takes place AT the source of the leak, do not try to extinguish the flame unless the supply of flammable gas can be stopped.
如果泄漏的源头起火，除非能够切断易燃气体供应，否则不要试图灭火。
2.If the flammable gas supply cannot be shut off, the continued escape of unburned gas can create an explosive mixture in the air.
如果易燃气体供应无法切断，不断逸出的未燃气体会在空气中形成爆炸性混合物。
3.Extinguishing a fire without eliminating the flammable gas supply can result in an accumulation of the gas and a possible explosion.
没有切断易燃气体供应而灭火可能导致气体的积累和可能的爆炸。
4.If the flammable gas source cannot be stopped, action must be taken to cool and to protect nearby equipment and cylinders from the fire.
如果易燃气体源头不能切断的话，必须采取行动来冷却和保护负荆的设备和钢瓶，以防它们起火。
5.In the case of liquid hydrogen, the atmosphere should be monitored with a flammable gas detector.
对于液氢，应当用易燃气体监测器来监测空气。
6.The flammable gas produced is accumulated and can be burnt directly, can be used for generating electricity.
产生的可然气体即可直接燃烧，也可用于发电。
7.A substance which in contact with water is liable to become spontaneously combustible or to give off a flammable gas.
在与水接触后容易变成自燃物或释放出可燃气体的物质。
8.flammable gas or liquid to be spread in the weld area should be seized by the relevant trial license only after the welding operation.
必须在易燃易爆气体或液体扩散区施焊时，应经有关部门检试许可后，方可施焊。
9.The hydrogen storage location should be permanently placarded: "Hydrogen -Flammable Gas - No Smoking - No Open Flames, " or equivalent.
氢储存点要永久性地张贴：“氢——易燃气体——禁止吸烟——禁止明火”，或其它意义一样的内容。
10.Compared with semi-spherical flammable gas cloud model, cylindrical model could represent cloud explosion accidents more exactly.
与半球形可燃气云模型相比，圆柱形模型更接近于气云爆炸事故的实际情况。
