Nguyen Manh Toan, deputy director of the provincial police department, said on Saturday the ban was issued by the department on the workers from specific workers from Binh Minh Wood Production and Trading Company.
The firm’s Chinese director, Feng Yong, has already been detained by local authorities.
The company has been engaged in the production and trade of wood products for over a decade, thanks to its foreign investment. It employs around 200 workers.
At around 8 a.m. on Wednesday, while 42 workers were on duty, a sudden explosion in the boiler resulted in the death of six people, including one Chinese. All were men aged 32-39. The accident also injured five other workers.
Initial investigations by authorities assessed that the explosion was caused by a technical error in the boiler. The day before the explosion, the boiler malfunctioned, and the company called a maintenance unit to repair it. The next day, as workers started the boiler, it exploded.
