Incident 1: Accident 1: In August 1985, a digging pile well under construction at a high-rise construction site with a diameter of 1.4m and a depth of 10.7m was stopped due to rain and returned to work when a worker returned to work two days later.

The air sample was taken at a depth of 5 meters before pumping water and the content of CO_2 was 13.5%, but neither H_2S nor CO was detected. Air samples were taken at depth of 8 meters, CO 2 content was detected as 12.4%
