Three fatalities at wind farm construction site in China

What happened

A single trade report, published in November 2025, says three workers died in June 2025 at a wind farm construction site in China. One worker is reported to have entered a wind turbine foundation pit where carbon monoxide had accumulated and to have suffocated. Two colleagues are reported to have died during attempts to rescue that worker. The site, the companies involved and the full findings of the underlying report are not given in the source available to the register.

Contributing factors

The summary states that carbon monoxide had accumulated in the foundation pit. How the gas accumulated, and why entry and the rescue attempts went ahead, are not reported.

Lessons learned

1. Turbine foundation pits can hold carbon monoxide so test the air before entry.
2. Rescue attempts in a pit without breathing protection can cause further deaths.
3. Control access to open foundation pits during construction to stop unsafe entry.
