At least 40 people have died after a platform under construction at a power plant’s cooling tower in eastern China’s Jiangxi province collapsed on Thursday, state news agency Xinhua said.

The accident happened in Fengcheng at around 7 am, and rescuers are on the scene, according to Xinhua, without giving further details.

The death toll was likely to rise because an unknown number of people were still trapped, it said. Five injured workers have been sent to hospital.

Deadly accidents are relatively common at industrial sites in China, and anger over lax standards is growing after three decades of swift economic growth marred by incidents from mining disasters to factory fires.

China has vowed to improve safety at such facilities. President Xi Jinping has said authorities would learn the lessons paid for with blood after chemical blasts in the port city of Tianjin last year killed more than 170 people.
