某公司总承包某厂煤粉制备车间新增煤粉生产线的机电设备安装工程,新生产线与原生产线相距不到10m,要求扩建工程施工期间原生产线照常运行,工程内容包括一套球磨机及其配套的输送、喂料等辅机设备安装;电气及自动化仪表安装;一座煤粉仓及车间的非标管道制作及安装;煤粉仓及煤粉输送管道保温;无负荷调整试运转。

项目部组建后立即着手下列工作:

(1)根据工程内容安排各专业的施工顺序。

(2)根据本工程的特点分析紧急状态并制订应急预案。

(3)制订球磨机吊装方案。球磨机简体单重50t,安装高度1.2m,拟采用90t汽车吊吊装,在现场许可的合适工况条件下90t汽车吊吊装能力为52t。

(4)制订安装质量保证措施和质量标准,其中对关键设备球磨机的安装提出了详尽的要求:在垫铁安装方面,每组垫铁数量不得超过6块,平垫铁从下至上按厚薄顺序摆放,最厚的放在最下层,最薄的放在最顶层,安装找正完毕后,最顶层垫铁与设备底座点焊牢固以免移位。

(5)制订煤粉仓施工方案。考虑到煤粉仓整体体积大,安装位置标高20m,故组对成两段吊装,就位后进行上下段连接焊缝的内外焊接。内部焊接时考虑到仓内空间狭窄,无通风孔,故暂打开仓顶防爆孔作为透气孔,并采用36V安全行灯作为内部照明。

问题

煤粉仓仓内焊接工作存在哪些安全隐患为什么应采取哪些解决措施?

Jonathan James looks like just another kid about to graduate from high school. But this 19-year-old Swede is anything but ordinary, from the computer in his parents’ home he helps the US Federal Bureau of Investigation(FBI) find out the world’s most wanted cyber criminals.

Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found out the maker of the "Melissa" virus in March 1999. He came to the aid of the FBI again on May 7, finding out the suspected sender of the dangerous "I LOVE YOU" virus. The suspect was caught in Manila on May 8.

Jonathan’s special skills are in hot demand as officials around the world express alarm at the "virtual" crimewave. In between studying for final exams, hanging out with friends and refereeing his younger brother’s football matches, the quiet, gentle teenager also gives lessons on e-security to large companies. He reads a lot and exchanges information with other computer experts to know much about the latest tricks of the hacker trade.

Many companies have already tried to employ him, but he is not interested at the moment. Instead, he plans to begin law school in the autumn at Sweden’s Uppsala University and start up his own e-security company.

Although he works with the FBI now, his family insists he’s just "a regular kid". "Jonathan is a great kid, he has his friends and he does a lot more than just play with the computer, " his little sister Tessa said, adding that he helps the FBI because "he likes to help", not because he’s looking for fame and recognition.

When the world was hit by the "Love Bug" virus, Jonathan was too busy preparing a speech on e-security to look into the problem. "Finally on May 7, I had some free time, so I began looking. " Within a few hours, he had found the suspect and e-mailed his method and results to the FBI. He said his work on the "Melissa" virus, which took three weeks to solve, was a big help in finding the suspect so quickly. "This time I knew exactly where to start, I knew what to disregard and what to look at.

The passage mainly wants to tell us that().

A. Swedish kid helps FBI find out the most wanted cyber criminals

B. Jonathan is really a quiet, gentle and ordinary boy

C. many companies want the young computer expert to join in

D. any cyber criminals will surely be found out wherever they are
