<Anchor> It was found that



we did not respond properly even though there was another opportunity to reduce the damage to people in the accident at that time.

In the event of a chemical spill, the work should have been stopped immediately and cleaned promptly, but there was a testimony that at the time workers who covered the toxic substances had to wipe the spilled material directly on the floor.



Following is the exclusive report by reporter Jo Yoon-ha.



<Reporter> According to



Occupational Safety and Health Standards, tetramethylammonium hydroxide and TMAH are classified as'acute toxic substances'.



Exposure to the human body can damage nerves and muscles and cause short-term breathing difficulties or even death.



Especially, if the concentration is over 25%, it is treated as toxic.



The concentration of TMAH spilled this time was as low as 2.4%, but the problem was the amount of spillage.



It was confirmed that 500L was spilled at the time of the accident.



[Deok-Hwan Lee/Professor Emeritus of Sogang University: Toxicity by chemicals is determined not by concentration, but by total amount.

If you inhale a lot, problems occur even at low concentrations.]



Testimony has

been reported

that coping after the accident was also very inappropriate.



According to an operator at the site, work has not stopped since the chemical leak.



Two workers, who are still unconscious, were instructed to do additional work while wearing poisonous substances.



"The LG Display supervisor instructed the two to wipe the chemicals off the floor with adsorption cloths," the worker said.



They wiped the chemicals off the floor and then fell one after another.



According to the site work guidelines, work must be stopped immediately in the event of a leak.



Regarding this, LG Display said that it was not instructed to clean the chemicals directly, and it was "confirming the exact facts."
