某施工单位承建一高层办公楼工程。在进行地下室聚氨酯防水涂料施工中,缺乏防火知识的工人甲在休息期间吸烟,由于涂料挥发形成的易燃气体浓度很大,地下室突然起火,造成4人重伤,2人医治无效死亡。 [问题]1.简要分析造成这起事故的原因。2.建筑工程施工现场常见的职工伤亡事故类型有哪些3.简述伤亡事故的处理程序。4.分部分项工程安全技术交底的要求和内容是什么
When the steam engine was invented in the t8th century, it began one of the greatest revolutions in our world. The invention of the petrol engine at the end of the 19th century led to another enormous change in our lives. And the computer is almost certainly going to be no less important an invention than these engines were. Just as there was a Stone Age, an Iron Age and so on, we have been living for centuries in a Paper Age, when almost all information was kept and sent on paper. However, to provide us with this paper, numerous trees have to be cut down every year. But now, with the computer, enormous amounts of information can be stored and sent without any paper, using small discs or the Internet. Computers allow one to send information to others anywhere in the world, through the Internet, and to receive information from them. One can send a long message more quickly from England to Australia, for example, than from one’s house to someone in the garden. Computers are not only used for writing; they can produce diagrams and pictures, and can even be used for playing games. They are a common sight at airports and railway stations, in hotels and restaurants; in fact, almost everywhere. We may infer that the fastest way to send messages is by using ______.
A. computer
B. air mail
C. discs
D. paper
