WASHINGTON, March 14 (Xinhua) —U.S. President Barack Obama confirmed on Saturday at the White House that China can have confidence in the American economy.

“Not just the Chinese government, but every investor can have absolute confidence in the soundness of investments in the United States,” Obama said.

“There is a reason why even in the midst of this economic downfall you have seen actual increases in investment flows here in the U. S.,”he said.

Obama also noted the U. S. will push for stricter regulation of the financial industry “front and center” at the upcoming Group of 20 Summit (峰会) in London ,ending an argument between the Europe and the United States over whether more focus should be placed on financial regulatory reform.

Chinese Premier Wen Jiabao said earlier Friady he is “a little bit worried ”about the safety of Chinese assets (财产) in the United States ,urging the U. S. government to ensure the security of those assets.

China has invested its huge foreign exchangereserves (外汇储备) in low-risk but low-yield assets ,such as U. S.government bonds (政府债券) ,to play it safe . According to the U.S. Treasury, China held 681.9 billion U.S. dollars  worth of U.S. government bonds as of November.

“China is indeed the largest creditor of the United States, which is the world’ s biggest economy .We are extremely interested in developments in the U. S. economy.”said Wen, adding that he is expecting the effect of the measures taken by the U.S.government to counter the global financial crisis.

Asked to react to Wen’ s concern, Lawrence Summers, director of the U.S. National Economic Council, noted on Friday that the U.S. will be sound steward (管家)of the money it invests.

某公司承担一项机电改建工程，工程量主要为新建4台5000m³原油罐及部分管线，更换2台重356t、高45m的反应器，反应器施工方法为分段吊装组焊。
针对作业活动，项目部风险管理小组对风险进行了识别和评价，确定了火灾、触电、机械伤害、窒息或中毒、焊接、应急响应等为重大风险。
在储罐防腐施工中，因油漆工缺员，临时从敷设电缆的外雇工中抽出两人进行油漆调和作业，其中一人违反规定，自带火种，在调和油漆时，引发一桶稀释剂着火将其本人烧伤，项目部立即启动应急预案，对他进行救护，并送往医院住院治疗。
项目部和该工人订立的劳务合同规定，因本人违反操作规程或安全规定而发生事故的责任自负，因此，事发当日，项目部将该名工人除名，并让其自行支付所有医药费用。项目部认为该名工人不属于本企业正式员工，故对该事件不作为事故进行调查和处理。
罐区主体工程完成后，消防系统的工程除了消防泵未安装外，其余报警装置已调试完，消防管线试压合格，业主决定投入使用4台原油罐，为了保证安全，购买一批干粉消防器材放在罐区作为火灾应急使用。

问题

1.指出项目部的风险评价结果有哪些不妥之处。
