The workers drowned in the basin in Changzhou Chienchin Grinding Material Co., Ltd. at about 1:20 p.m., according to rescuers.
They were all from the Hailan Environmental Protection Engineering Company in Jiangsu's capital city of Nanjing, which had been commissioned by the Changzhou company to dismantle the basin since Nov. 16.

Located in the Trina Photovoltaic Industry Zone in Changzhou's Xinbei district, the company is mainly engaged in the disposal of used slurry from silicon carbide (SIC) and polyethylene glycol (PEG).
An investigation into the cause of the accident is under way.
