A worker employed by San Francisco’s Human Services Agency as a condition to receive welfare was run over and killed by the driver of a Department of Public Works truck this morning, a city agency spokesperson has confirmed.

According to DPW spokesperson Rachel Gordon, a DPW crew was out on the usual route it follows to clean up illegal dumping when the driver of the truck ran over and killed a male member of the crew, Bay City News reports. He has since been identified as Alvin Andrews of San Francisco.

The Chron reports that the four-member crew was made up of two DPW staffers and two "part-time general assistance workers who work on public works crews as a condition of receiving welfare."

The driver of the truck was a DPW worker, according to the Chron. Andrews was one of the general assistance workers.

The crew was out picking up illegally-dumped trash at Jerrold Avenue and Quint Street in the Bayview at around 9 a.m. when, DPW Director Mohammed Nuru tells the Chron, Andrews slipped while in front of the truck on the opposite side of the driver, who then accidentally ran him over.

Andrews was pronounced dead at the scene.

The cause of the fatality remains under investigation by the SFPD, Cal/OSHA, and DPW, Gordon said. Meanwhile, the driver will be tested for drugs and alcohol, as is standard procedure.

Update: At 4:23 this afternoon, Mayor Lee today issued this following statement:

“On behalf of the City and County of San Francisco, I extend my deepest condolences to the family of Alvin Andrews who tragically died in an accident this morning while working for our Department of Public Works. The safety of our workforce is our highest priority, and this incident will be thoroughly investigated. Our thoughts and prayers remain with Alvin’s family and friends during this time of mourning.”
