Carbon monoxide gas prevents the body from absor bing oxygen. Vict ims of carbon mo noxide poisoning get sleepier and sleepier until the y lose conscious ness, never to re gain it.
All over Pompeii, peo ple lay down on beds of pumice stones, ove rwhelmed by the gas, and death came quietl y to them.

The deadly shower of stones and ash went into its second day. But it no longer matt ered to Pompeii whet her the eruption conti nued another day or another year. For by midday on August 25 , Pompeii was a city of the dead.
How to escape from the volcanic eruption
1.Deal with lava hazards. In volcanic hazards, the lava flows may be lifethreatening minimal, because people can run out route lava flow 应对熔岩危害。在火山的各种危害中，熔岩 流可能对生命的威胁最小，因为人们能跑 出熔岩流的路线。
2.Respond ejecta hazards. If the eruption of the volcano near escape from, the kind of hard helmets used by construction workers, motorcycle riders were riding helmet or helmet will give you some protection. 应对喷射物危害。如果从靠近火山喷发处逃 离时，建筑工人使用的那种坚硬的头盔、 摩托车手头盔或骑马者头盔将给予你一定 的保护。
3.Respond gas bulb hazards. If there is no solid underground buildings nearby, the only chance of survival is probably jumped into the water; hold your breath for half a minute or so, balls will roll over. 应对气体球状物危害。如果附近没有坚实的 地下建筑物，惟一的存活机会可能就是跳 入水中；屏住呼吸半分钟左右，球状物就 会滚过去。
Remember: Before the eruption of the volcano increased activity often accompanied by rumbling and overflow vapors and gases, sulfur from local rivers can smell. Do not take the canyon route, it may become lahars through road. 切记：火山在喷发之前常常活动增加， 伴有隆隆声和蒸气与气体的溢出，硫 磺味从当地河流中就可闻到。不要走 峡谷路线，它可能会变成火山泥流经 过的道路。
