A New Zealand engineer and a Thai man are reported to have been killed trying to rescue a couple that passed out due to a gas leak at a biomass power plant in southern Thailand.
Police said the two perished at the plant in Trang province, 680km south of Bangkok, as they tried to reach the couple inside a three-storey ventilation chimney.
Police are quoted by the Bangkok Post as saying the accident happened shortly after midnight on Sunday (local time), when the husband and wife passed out from toxic gas believed to be ammonia, DPA reports.
The unconscious couple were later pulled to safety by other employees of the biomass plant.
