Truck driver killed at north Phoenix's TSMC facility, police say

A waste disposal truck driver was killed in an apparent accident at the construction site of Taiwan Semiconductor Manufacturing Company in north Phoenix on Wednesday.

According to Phoenix Police, officers responded to a construction site near Dove Valley and 43rd Avenue to reports of an incident involving possible waste material in a tractor trailer at around 2:30 p.m. on May 15.

Phoenix Fire was first at the scene, where crews decontaminated the area and treated the truck driver, identified as 41-year-old Cesar Anguiano-Guitron.

Anguiano-Guitron was taken to a hospital where he later died.

Investigators say Anguiano-Guitron was transporting waste material away from the construction site when the incident happened.

"[Anguiano-Guitron] was made aware of a possible issue involving the tank containing the material, which was stored under pressure," Sgt. Phil Krynsky said. "While inspecting the equipment, an uncontrolled pressure release occurred, which resulting in Anguiano-Guitron being struck by a blunt object and thrown over 20 feet from the trailer where he suffered life-threatening-injuries."

TSMC released a new statement on Thursday:

"We extend our deepest condolences to the family and loved ones of the man who passed away in yesterday’s tragic accident which occurred on our site. We care about the safety and wellbeing of each of our employees, our construction trade workforce and vendors, as well as every visitor to our site. We are grateful for the immediate emergency response and the first responders for their efforts.

The Phoenix Fire Department cleared the site as hazard free yesterday soon after the accident, and there has been no interruption to full operations and construction. As was corrected by the Phoenix Police Department in their media advisory last evening, this individual was inspecting the equipment on a disposal truck when an unintended pressure release occurred. We will continue to stay in communication with the authorities as they complete their investigation as to the cause of this incident, also in cooperation with the employer of the individual."
