BEIJING—Chinese authorities said they detained 13 people over the collapse of scaffolding at a power plant construction site that killed 74 workers in one of China’s most serious industrial accidents in years.
Most of the dead had been working on the interior concrete wall of a massive circular cooling tower 70 metres (230 feet) up when the scaffolding collapsed Thursday morning.
Although authorities did not disclose details about the 13 detentions, the focus of the investigation has turned to the power plant’s operator, Jiangxi Ganneng, and a major engineering firm, Hebei Yineng, which has taken on multiple high-profile power plant projects and has a history of workplace fatalities.
Yineng has won contracts to build plants in more than a dozen provinces and in Turkey and Malaysia, according to previous interviews given by executives. In 2012, seven Yineng builders in a cooling tower in Yunnan province tumbled to their deaths after scaffolding collapsed. Three years before that, two workers died after a vehicle accidentally backed into a scaffolding support beam at a Yineng-built cooling tower in Guangdong province.
Several of the company’s publicly listed telephone lines and a mobile phone number for the company’s legal representative rang unanswered on Friday. The company’s websites could not be opened.
State media reports said the accident occurred during a change of work shifts, possibly accounting for the high death toll. Workers had also been toiling around-the-clock in three shifts to make progress on the project ahead of the arrival of bitter winter weather, according to local media interviews with surviving employees.
The 1,000-megawatt coal-fired plant had been designated a priority project by the province, likely adding to the pressure on workers.
Chinese President Xi Jinping has urged local governments to hold those responsible accountable and an investigation was underway.
China has suffered several major work-safety accidents in recent years blamed on weak regulatory oversight, systemic corruption and pressure to boost production amid a slowing economy.
