TSMC suspended related construction work at Kaohsiung’s F22 P4 site after a fall killed three workers and injured one other.

The incident occurred at a new-construction site. The supplied report says four workers fell while welding steel beams at the F22 P4 construction project in Kaohsiung’s Nanzih park on October 20. Three died, while the fourth was receiving hospital treatment.

TSMC said related on-site work had been suspended. Its safety team was cooperating with authorities investigating the incident. The company was also assisting the subcontractor with follow-up matters.

The reported suspension is specific to related construction activities. The source does not establish a shutdown of operating semiconductor production or quantify an effect on wafer output. It also provides no revised project-completion schedule.
