Four members of a family died -- most likely from suffocation -- after falling into a waste container at a shrimp processing company in the Mekong Delta province of Hau Giang Saturday.
The accident happened at around 7 p.m. when Dao Hien Phuong, a 45-year-old worker at Vietnam Chitin Hau Giang Ltd. Co, checked the empty container to do some cleanup work.
Phuong allegedly found the container's valve broken, so he erected a ladder to climb in and check things out from the inside.
He passed out as soon as he entered the container.
Dao Vu Khanh, his 20-year-old son, climbed into the container to save Phuong, but he also passed out.
Phuong's two nephews, named Dao Hien Ngoan and Dao Hien Dang, both 30, also climbed into the container to pull Phuong and Khanh out.
The pair then suffered the same fate.
Other workers from the company then broke the container to pull the four out and rushed them to the hospital.
Phuong and Khanh, however, were dead upon arrival.
Ngoan and Dang died the following day.
The four deceased workers are all relatives of the company's owner.
The cause of the deaths is still being investigated.
