On May 15, 2024, 41-year-old Cesar Anguiano-Guitron died at TSMC's Arizona facility when a container of over-pressurized sulphuric acid exploded. Arizona OSHA cited TSMC for failing to keep the workplace free from hazards likely to cause death or serious harm, finding violations including over-pressurization, harmful material exposure, and falling debris risks. Workers reported lack of clear emergency guidance and cell phone signal issues that delayed emergency response. The fine was only $16,131.
