A 41-year-old man died Wednesday after being struck by a blunt object in an explosion that threw him 20 feet from the tractor trailer he had been driving at the TSMC factory in north Phoenix, police said.

Cesar Anguiano-Guitron was transporting waste material from a construction site when he was made aware of a possible issue involving the tank containing the material, which was stored under pressure, Phoenix police detectives stated in a release.

“While inspecting the equipment, an uncontrolled pressure release occurred,” the release stated.

The Phoenix Fire Department was first on scene and worked to decontaminate the area and provide aid to Anguiano-Guitron. He was rushed to a hospital where he died, police said.

Taiwan Semiconductor Manufacturing Co. facility is near 51^st Avenue and Dove Valley Road.

An investigation is underway, police said.

"We extend our deepest condolences to the family and loved ones of the man who passed away in (Wednesday's) tragic accident which occurred on our site," a TSMC Arizona spokesperson said. "We care about the safety of our employees, our construction trade workforce and vendors. 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 (Wednesday) soon after the accident and there has been no interruption to full operations and construction," the TSMC spokesperson said. "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."
