At 9:42 am on April 26, 2023, the Changzhou Fire Detachment received a call for help. Three workers were trapped in two sewage pools and were already unconscious. After the Zhixi Fire Fighting Team arrived at the scene, they divided into two groups to launch rescue operations. The sewage pool is 5 meters deep. The firefighters put on breathing apparatus, carried safety ropes and air bottles and went down to the sewage pool for rescue. After finding the unconscious worker, the rescuers provided oxygen to the unconscious worker while taking safety precautions and carefully pulling the workers to the ground. After about 30 minutes of intense rescue, the three trapped people trapped in two sewage pools were rescued. According to the fire department, two workers were painting the sewage tank at the time, and two co-workers were watching over it. The workers working in the pool did not wear protective masks. After inhaling harmful gases for a long time, they became dizzy and then passed out. A care worker went to the pool to check and was trapped in the pool. Fortunately, there was another worker up there who noticed something was wrong in the pool, and the worker immediately called the police for help. Two workers are still receiving treatment in the hospital's intensive care unit.
