Police in the southern province of Ba Ria-Vung Tau are investigating the deaths of three workers at a seafood factory suspected of gas poisoning after they entered its wastewater tunnel Thursday.
The accident occurred at around 8:50 a.m. at Trong Duc Seafood Company's factory based in Tan Hai Commune.
Nguyen Van Chien, 27 and Nguyen Thanh Toan, 31, reportedly opened the tunnel and climbed down a ladder to collect fish scales when they fainted and fell into the water.
The tunnel is four meters deep and the water level was nearly 1 meter deep at the time.
Bui Van Hung, 31, saw the accident and climbed inside to rescue his colleagues, but also fainted.
Several other workers managed to pull them out and rushed them to Ba Ria Hospital for treatment.

Police are investigating the incident.
Last month, five workers and one manager of a company in the Mekong Delta Province of Dong Thap climbed into a fish oil tank and drowned to death.
One worker had fallen into the tank and his four colleagues and their boss climbed inside to rescue him.
