August 3rd, a post was uploaded on Facebook and national petition. The post said that when the Facebook user's sister was taken to the hospital, she was already in cardiac arrest, so she suffered serious brain damage. The post added that the doctor in charge said that her sister has to lie down in bed for all her life without consciousness. The blood condition is not good either. She doesn't know when her sister will become conscious. What has happened to her sister?

The Facebook user's sister, 19 years old, has lost her consciousness at the public restroom of Milak-dong, Suyeong-gu, Busan. She was discovered by his boyfriend because she did not come out for about 20 minutes, her boyfriend was worried about her and found his girlfriend lying. He tried CPR, but he also passed out after a few minutes while doing CPR. They were discovered by a passerby and were saved. However, the girlfriend has still not regained consciousness.

So, what was the reason made the two youths to pass out? The reason was hydrogen sulfide. At the restroom where the girlfriend knocked out, the police and the Korea Occupational Safety and Health Agency said that 1,000 ppm of hydrogen sulfide, which is 60 times higher than the permissible concentration level of 15 ppm under the Industrial Safety and Health Act, was found in the toilet. Hydrogen sulfide occurs when substances decay in oxygen-free environments. The sewage treatment facility at the center was cleaned automatically between 3 a.m. and 4 a.m. every day, but police and others are investigating exactly how hydrogen sulfide was exposed through drainage holes in the bottom of the sink in the public toilet due to problems with the exhaust system during the work process.
