国内外许多事实表明,事故最容易发生的时间是凌晨4点和午后4点左右。苏联切尔诺利贝、美国三里岛核电站事故及印度博帕尔毒气溢漏事故均发生在夜间。我国某拖轮运输部门两年里共发生海上事故28起,其中50％发生在凌晨2—7点。 Many facts at home and abroad show that accidents are most likely to occur at 4 a.m. and 4 a.m. Chernobyl of the Soviet Union, the accident at Three Mile Island nuclear power plant in the United States and the Bhopal gas spill in India all occurred during the night. A tugboat transport department in our country has 28 maritime accidents in two years, of which 50% occurred at 2-7 am.
