TSMC plant in north Phoenix: Garbage truck driver dies

A garbage disposal vehicle driver died in an accident at the construction site of Taiwan Semiconductor Manufacturing Company on Wednesday afternoon, a company spokesman said.

Authorities previously reported that a man was taken to a hospital after an explosion was reported on the north Phoenix campus at 2:30 p.m. Phoenix police reported later Wednesday evening that the truck driver, identified as 41-year-old Cesar Anguiano-Guitron, had died, according to a news release.

“No TSMC employees or construction workers on site reported any related injuries. There was no damage to our facilities,” TSMC Arizona said in a statement.

“We work closely with the local authorities. This is an active investigation and no further details can be released at this time.”

TSMC released an additional statement Thursday to express its condolences to the “family and loved ones of the man who died in the tragic accident on our premises yesterday.”

“We care about the safety of our employees, our construction workforce and our suppliers. We are grateful for the immediate emergency response and first responders for their efforts,” the statement said.

According to the Phoenix Fire Department, firefighters from multiple departments responded to a reported hazardous materials call Wednesday afternoon.

According to the Phoenix Fire Department, units from the Phoenix, Glendale and Daisy Mountain fire departments were dispatched to TSMC near Dove Valley Road and 43rd Avenue around 2:30 p.m.

According to the Phoenix Fire Department, the emergency call was made due to an explosion at the facility.

The Phoenix Fire Department was first on scene and worked to decontaminate the area and provided aid to the tractor-trailer driver.

According to TSMC, the Phoenix Fire Department deemed the site safe on Wednesday shortly after the accident. There were no interruptions to operations or construction.

“As the Phoenix Police Department corrected in its media release last night, this individual was inspecting equipment on a disposal truck when an accidental depressurization occurred.

“We will continue to remain in contact with authorities as they complete their investigation into the cause of this incident, including in collaboration with the individual’s employer,” the TSMC statement said.

How did the explosion happen?

Police said the investigation revealed that Anguiano-Guitron was using his tractor-trailer to haul waste material away from the site. He was made aware of a possible problem in the tank with the pressurized material.

While inspecting the equipment, an “uncontrolled depressurization” or explosion occurred, resulting in Anguiano-Guitron being struck by a blunt object and ejected over 20 feet from the trailer, the release said. He suffered life-threatening injuries and was taken to hospital, where he later died.
