On October 20, a major industrial accident occurred at the TSMC F22 P4 construction site in the Nanzi District of Kaohsiung. During steel structure hoisting operations, a bolt failure caused four subcontracted workers to fall from approximately three stories high.

The Southern Taiwan Science Park Bureau reported that two individuals were in cardiopulmonary arrest before reaching the hospital, one sustained serious injuries, and one sustained minor injuries. TSMC voluntarily suspended work at the site to cooperate with investigations.

The Southern Taiwan Science Park Bureau has ordered an immediate work stoppage and prohibited the movement of the accident scene to determine if the employer or business unit violated the Occupational Safety and Health Act.
