How Did Four Construction Workers Die in a Fall at TSMC's Kaohsiung Site?

Quick answer: Four construction workers were killed on Tuesday 20 October 2026 during steel-structure construction work at TSMC's new factory site in Kaohsiung, southern Taiwan. TSMC said it and its construction contractor immediately suspended related construction work at the site, and the chipmaker's on-site safety team is cooperating with the relevant authorities as investigations proceed.

Key facts

• What: Construction-site accident — workers fell from a steel structure
• Where: TSMC's new factory construction site (F22 plant, Nanzih campus), Kaohsiung, southern Taiwan
• When: Tuesday, 20 October 2026
• Toll: 4 construction workers killed
• Reported by: Reuters, 21 October 2026 (Wen-Yee Lee and Ben Blanchard)

What happened

Four construction workers were killed on Tuesday during steel-structure construction at the site for a new factory in Kaohsiung, southern Taiwan, chipmaker TSMC said on Wednesday. Reuters reported that the workers fell from height while engaged in steel-structure construction work at the site, part of TSMC's F22 plant in the Nanzih campus area of Kaohsiung. Early reports on the day of the accident initially put the toll at three dead with one worker injured; TSMC later confirmed four deaths.

Response and investigation

TSMC said it and its construction contractor "immediately suspended related construction work at the site", and comparable steel-structure construction work elsewhere in Taiwan was also paused as a precaution. TSMC's on-site safety team is cooperating with the relevant authorities while the investigation into the cause continues. Reuters noted that TSMC is the world's largest contract chip maker and a major supplier of the advanced chips powering artificial-intelligence hardware.

Why it matters

The accident is a rare fatal industrial accident at a flagship semiconductor facility project. TSMC's Kaohsiung expansion is among the most significant chip-manufacturing investments in Asia, and the suspension of steel-structure work underlines the scale of the safety response. The toll and the construction halt were reported by global news wires including Reuters and Bloomberg within hours.
