A strong wind was throwing workers into windows of the 46-story building, after which rescuers managed to stop the uncontrollable movement. But it was too late. They were up there for about twenty minutes. Both men were pronounced dead after being transported to the hospital. The window cleaners, who were 34 and 54 years old, were given a task by their superior, despite the bad weather. The project leader has been arrested, and further details of the incident are still being investigated by local authorities. On May 10, when the video was shot, the wind in some parts of Wuhan reached up to 97 kilometers per hour. His strength thus reached level ten on the Beaufort scale. Local regulations on work safety prohibit carrying out work at heights when the wind exceeds the fifth stage.
