Caution: Experiments conducted by students on weekends/at night

Every year, from January through March, students tend to work very hard to complete their Master's/Doctoral thesis, conducting research or experiments even on weekends and at night, which can cause accidents or health problems due to irregular working hours, accumulated fatigue, and lack of sleep. Below are some of the cases that happened at the University this year.

Case 1

On a Friday in January 2012 at around 10 p.m., a student shattered his ankle badly when he was rushing down the stairs to get home quickly. This resulted in a three-week-long sick leave.
(Accumulated fatigue caused by long hours of work on a doctoral thesis may have caused the accident.)

Case 2

On a Saturday in January 2012 at around 10 a.m., a student carelessly stabbed his thumb with an experiment knife during an experiment.
(Accumulated fatigue in preparing for a research demonstration may have caused the accident. Also, he should not have conducted a dangerous experiment alone.)

Case 3

On a Saturday in February 2012 at around 10 a.m., a student fainted while presenting a research demonstration and was taken to a hospital.
(Lack of sleep and accumulated fatigue caused by long hours of work for the demonstration may have caused the student to faint.)

Case 4

On a Thursday in January 2012 at around 1 p.m., a student operated a processing machine in the wrong way and was almost injured by a piece of the machine, which scattered into pieces in the laboratory.
(Lack of sleep and accumulated fatigue caused by long hours of work may have caused the accident.)

Things to remember

  • Conduct experiments in a systematic way so that you will not have to work on weekends and/or at night.
  • In case an experiment must be conducted on weekends and/or at night, your supervisor should know about it and advise you on the necessary procedures in advance. Refrain from working alone in the lab.
  • Do not conduct an experiment when feeling sleepy and/or exhausted.
  • Make sure to be informed of the emergency contact list of your lab.
