Investigation results said the toxic gas was produced under high temperature after the reservoir was closed for 32 days. 

The leak was discovered when a man, identified by his surnamed Huang, lost consciousness around 9 a.m. Monday while working in reservoir pit at his home in Tangna Village, Pingguo County.

Eight villagers who attempted to rescue him also fell unconscious. 

The nine were rushed to hospital, where they later died despite medical attention.
